(assembling)
Next, the order of assembling the situation of iris apparatus 1 with described each component part is generally described.In addition, at this, as an example, before a pair of aperture blades 3,4, filter unit 24 and blade shroud 6 are installed on respectively aperture substrate 2, aperture drive division 7 and optical filter drive division 8 are installed on aperture substrate 2.
At first, aperture blades 3 is installed on aperture substrate 2.At this moment, with jut 11a, the 11c of aperture substrate 2,11d is embedded into respectively in guiding groove 16a, 16b, the 16c of aperture blades 3.In addition, a drive pin 34b with aperture drive division 7 is embedded in the connecting hole 17 of aperture blades 3.
Next, filter unit 24 is installed on aperture substrate 2.In this case, embed the bolster 35 of aperture substrate 2 in the circular hole 26 of arm 25, and, the not shown drive pin of embedding optical filter drive division 8 in the slotted hole 27 of arm 25.
Next, aperture blades 4 is installed on aperture substrate 2.At this moment, with in jut 11a, the 11b of aperture substrate 2, guiding groove 19a, 19b that 11c is embedded into respectively aperture blades 4,19c.In addition, another drive pin 34a with aperture drive division 7 is embedded in the connecting hole 20 of aperture blades 4.
Next, blade shroud 6 is installed on aperture substrate 2.At this moment, the bolster 35 of aperture substrate 2 is embedded in the slotted hole 33 of arm 32 of blade shroud 6.Such as carry out the fixing of aperture substrate 2 and blade shroud 6 by chimeric grade.
When like this blade shroud 6 being installed on aperture substrate 2, the interference of both positions is as described below to be avoided like this.At first, pass the connecting hole 17 of aperture blades 3 and the interference utilization of drive pin 34b of outstanding aperture drive division 7 and the position between blade shroud 6 is kept out of the way slot part 31b and avoided.Equally, pass the connecting hole 20 of aperture blades 4 and the interference utilization of another drive pin 34a of outstanding aperture drive division 7 and the position between blade shroud 6 is kept out of the way slot part 31a and avoided.In addition, jut 11a, the 11c of aperture substrate 2 and the interference of the position between blade shroud 6 utilize the pair of holes 36a of section, 36b to avoid, and jut 11b, the 11d of aperture substrate 2 and the interference of the position between blade shroud 6 utilize a pair of notch part 37a, 37b to avoid.
In the situation that assemble like this iris apparatus 1, a pair of aperture blades 3,4 utilizes 4 jut 11a, 11b, 11c, 11d to move (slip) on aperture substrate 2 and supports freely.In addition, filter unit 24 is supported to the direction with heart rotation in bolster 35 and moves freely.In addition, the peristome 10 of aperture substrate 2 is configured at the relative state of the thickness direction of aperture substrate 2 (state of coincidence) with the peristome 30 of blade shroud 6, and, in this relative part, the state that the hole section 15 of aperture blades 3 and the bend 18 of aperture blades 4 are configured to overlap.
The diameter of the semi-circular portions of the diameter of the circular shape of the hole section 15 of regulation aperture blades 3 and the bend 18 of regulation aperture blades 4 is roughly the same size.And under the state that 2 aperture blades 3,4 are overlapped each other, the part that overlaps at the bend 18 of the hole of aperture blades 3 one 15 and aperture blades 4 forms aperture openings.Thereby, zoomed in or out in the peristome 10 of aperture substrate 2 zone relative with the peristome 30 of blade shroud 6 by a pair of aperture blades 3,4 aperture openings that form.But, because also there is the fully closed situation of aperture openings in the difference of aperture blades 3,4 position.
(detailed description of filter sheet base plate)
At this, the structure of described filter sheet base plate 5 is illustrated in further detail.
Fig. 3 is the vertical view that the filter unit in embodiment is amplified.In addition, Fig. 4 is the cut-open view of filter sheet base plate.In addition, the dotted line of circle shown in Figure 3 represents to be formed on the opening of framing component.
Filter sheet base plate 5 for example glass substrate 40 constitutes base.As an example, glass substrate 40 adopts ultraviolet ray (UV) cut-off glass.Be formed with infrared intercepting filter layer 41 and ND (Neutral Density) filter layer 42 on a first type surface of filter sheet base plate 5.Infrared intercepting filter layer 41 is filter layers that the light to region of ultra-red (comprising near infrared region interior) ends.For infrared intercepting filter layer 41, spread all over the whole of this first type surface in the mode of whole that covers this first type surface and form regionally on a first type surface of glass substrate 40.In addition, infrared intercepting filter layer 41 is formed on glass substrate 40 with identical thickness.By form like this infrared intercepting filter layer 41 on glass substrate 40, the zone that is formed with this infrared intercepting filter layer 41 becomes the zone that the light to infrared spectral range interdicts.In addition, glass substrate 40 is formed by ultraviolet cutoff glass, and therefore, its whole zone becomes the zone that the light to the ultraviolet range interdicts.Thereby the state that the zone that is formed with infrared intercepting filter layer 41 of glass substrate 40 becomes the light that has been equivalent to remove infrared spectral range and ultraviolet range makes zone that visible light passes through, is the zone that visible light passes through the zone.But visible light strictly says it can is not also the zone that visible light is passed through by the zone.Particularly, by visible light by the light in zone in except comprising visible light, also can comprise a part that belongs to the ultraviolet range light, belong to the light of the part of infrared spectral range.
With respect to this, ND filter layer 42 is the filter layers that make the optical attenuation that incides this ND filter layer 42.In addition, ND filter layer 42 is to compare the lower filter layer of wavelength dependency with the zone that is formed with infrared intercepting filter layer 41 (following also be denoted as " visible light is by the zone ").Thereby, the zone that is formed with ND filter layer 42 be equivalent to make by in the light of aperture openings, at least can be by visible light the zone by the optical attenuation in zone, be the zone in optical attenuation zone.For example, only be visible light if can pass through regional light by visible light, the zone that makes this visible light decay is the optical attenuation zone.In this case, the transmissivity of the visible light in ND filter layer 42 also depends on the characteristic that is assembled into the capturing element in video camera, but is preferably for example 6% left and right.But ND filter layer 42 has the wide transmissivity of the characteristic of decay equably that causes that can make ultraviolet range, visible region and infrared spectral range each zone.Therefore, the light that can decay with ND filter layer 42 is not limited to visible light.
In the first type surface of filter sheet base plate 5, as the relative Area Ratio of visible light by zone and optical attenuation zone, in the situation that the area of the visible light that effectively works when aperture openings is formed full-gear by the zone is made as 100%, preferably the area in optical attenuation zone accounted for this ratio of 100% and be set as 4～33%.The reason that like this Area Ratio in optical attenuation zone is defined as wider scope is, the aperture openings footpath of the Area Ratio of the visible light when being full-gear with respect to aperture openings by the area in zone suitable optical attenuation zone during by this standard-sized sheet changes.Particularly, the Area Ratio that the aperture openings footpath during along with standard-sized sheet becomes large, suitable optical attenuation zone diminishes, and in contrast, the aperture openings footpath during along with standard-sized sheet diminishes, and the Area Ratio in suitable optical attenuation zone becomes large.
Can clearly learn from accompanying drawing, ND filter layer 42 is to have the central part that is formed on filter sheet base plate 5 than the regional little zone that is formed with infrared intercepting filter layer 41.In addition, the zone that is formed with as described above infrared intercepting filter layer 41 is equivalent to visible light by the zone.Therefore, ND filter layer 42 is formed on visible light by in the zone.
Opening size when as shown in Figure 5, the physical dimension of ND filter layer 42 (situation of legend is diameter) and a pair of aperture blades 3,4 formed aperture openings 43 are for the state of little aperture is set accordingly.In this manual, the state of so-called little aperture refers to that the aperture area of actual aperture openings 43 is the state below 1/3 that makes the aperture area that aperture openings 43 standard-sized sheets make.Under the state of little aperture, utilization is in the barbed portion that is in the shape of the letter V of the part formation of the hole of aperture blades 3 one 15, with the barbed portion that is in the shape of the letter V that a part at the bend 18 of aperture blades 4 forms, the opening shape of aperture openings 43 becomes quadrilateral (rhombus).
For form the concrete manufacturing gimmick of the situation of infrared intercepting filter layer 41, ND filter layer 42 on glass substrate 40, adopt known film build methods such as vacuum vapour deposition, sputtering method, coating process to get final product.In addition, in the situation that form ND filter layer 42 after forming infrared intercepting filter layer 41 on glass substrate 40, need the formation zone of restriction ND filter layer 42.In this case, forming ND filter layer 42 under the state that carries out mask process on the glass substrate 40 that is formed with infrared intercepting filter layer 41 in the mode of only part of wish formation ND filter layer 42 being carried out opening gets final product.
In addition, as described above in the situation that filter sheet base plate 5 is entered on the light path of incident light and forms use state, the center contraposition of the center of filter sheet base plate 5 and a pair of aperture blades 3,4 formed aperture openings.Therefore, under the use state of filter sheet base plate 5, the zone (optical attenuation zone) that is formed with ND filter layer 42 is concentric shape configuration with aperture openings.Thereby when making aperture openings form the state of little aperture, the ratio that the area of ND filter layer 42 accounts for the aperture area of aperture openings becomes very high.Particularly, take in (etc.) in the situation that bright environment, aperture openings diminishes with shrinking in the room under fine day outside, therefore, configures ND filter layer 42 in the mode in the whole zone of blocking aperture openings.
＜3. the action of iris apparatus＞
Then, the action of the iris apparatus 1 of embodiments of the present invention described.
[3-1. adjusts the action of aperture openings]
At first, the basic operating principle of iris apparatus 1 described.
In the situation that to being adjusted by a pair of aperture blades 3,4 aperture openings that form, drive aperture drive division 7.So, a pair of aperture blades 3,4 is subject to the driving force of aperture drive division 7 and is relatively moving on approaching direction separately.
As mentioned above, in the situation that a pair of aperture blades 3,4 is relatively moved, the size of aperture openings 43 changes according to a pair of aperture blades 3,4 moving direction and amount of movement.Particularly, when the direction (direction of arrow of the solid line of Fig. 5) that a pair of aperture blades 3,4 approaches towards each other is mobile, aperture openings 43 becomes greatly thereupon, and when a pair of aperture blades 3,4 directions of separating towards each other (direction of arrow of the dotted line of Fig. 5) movement, aperture openings 43 diminishes thereupon.In addition, make under a pair of aperture blades 3,4 immediate states, aperture openings 43 become maximum (becoming full-gear), make under a pair of aperture blades 3,4 states that separate most aperture openings 43 become minimum (becoming the state of complete closure or the state close with the state of complete closure).
Fig. 6 means the figure of the state that makes aperture openings open (standard-sized sheet).In the situation that take with the black and white screening-mode, filter sheet base plate 5 becomes the state of having kept out of the way from aperture openings 43.Fig. 7 means the figure that makes aperture openings 43 form the state of little aperture.In the situation that make aperture openings 43 form little aperture, also as shown in Figure 5 above, in the part that a pair of aperture blades 3,4 hole section 15 overlap with bend 18, aperture openings 43 forms almost diamond.And, configuration ND filter layer 42 under the state of this aperture openings 43 all being blocked (covering).But, the situation on the light path that configuration ND filter layer 42 on aperture openings 43 refers to only make filter sheet base plate 5 enter into incident light.
[3-2. switches the action of screening-mode]
As the form of the switching of screening-mode, exist from colored screening-mode switch to the black and white screening-mode situation, switch to the situation of colored screening-mode from the black and white screening-mode.But, when switching screening-mode, all drive optical filter drive division 8 in arbitrary situation.The below's minute situation describes.
At first, in the situation that screening-mode is switched to the black and white screening-mode from colored screening-mode, be subject to the driving force that produces along with the driving of optical filter drive division 8, filter unit 24 moves centered by bolster 35 rotatably.Thus, filter sheet base plate 5 is kept out of the way the position of leaving from the light path of the light of incident by aperture openings 43.Therefore, in the situation that take with the black and white screening-mode, the light of incident does not just arrive capturing element (not shown) via filter sheet base plate 5 by aperture openings 43.Thereby, much less by the reduction of infrared intercepting filter layer 41 caused light quantity, the reduction of the light quantity that caused by ND filter layer 42 can not occur yet.Therefore, become the pattern of the shooting at night of being suitable for the less light quantity of requirement and necessary exploring degree etc.
With respect to this, in the situation that screening-mode is switched to colored screening-mode from the black and white screening-mode, so that direction of action drives optical filter drive division 8 towards the mode of the direction opposite with above-mentioned situation.So, be subject to the driving force of optical filter drive division 8 and filter unit 24 moves rotatably centered by bolster 35.Thus, filter sheet base plate 5 enters into the position on the light path of the light of incident by aperture openings 43.Therefore, in the situation that take with colored screening-mode, the light of incident arrives capturing element (not shown) via filter sheet base plate 5 by aperture openings 43.
At this, colored screening-mode is applicable to the bright environment such as daytime.In addition, in such shooting environmental, under the state of the little aperture that makes like that as described aperture openings 43 shrink littlely in the undersaturated mode of signal of the pixel of capturing element, carry out the light quantity adjustment by iris apparatus 1.Therefore, become the state that the whole of aperture openings 43 or more than half part are blocked by the optical filter functional layer of the bilayer that is made of infrared intercepting filter layer 41 and ND filter layer 42.Thereby, even adopt the structure that is separately installed with the ND optical filter on a pair of aperture blades unlike existing, the optical filter function of infrared intercepting filter layer 41 and ND filter layer 42 is concured.Therefore, become and be suitable in the pattern of shooting environmental for the shooting on bright daytime etc.
In addition, even the time of waiting by day band, is also considered under the environment of duskiness and is taken for the relation that place etc. is set of the situation of weather variation or video camera such as also.Under these circumstances, in order to ensure the light quantity of necessity, make aperture openings 43 openings must be larger than the state of little aperture under the state that keeps making after filter sheet base plate 5 enters.Thereby aperture openings 43 openings must be regional larger than the formation of ND filter layer 42.With respect to this, infrared intercepting filter layer 41 is formed on one-sided whole of filter sheet base plate 5, therefore, even aperture openings 43 is opened into full-gear, the mode of also blocking aperture openings 43 with infrared intercepting filter layer 41 all the time configures infrared intercepting filter layer 41.Therefore, in the situation that take with colored screening-mode, even increase aperture openings 43 in order to ensure light quantity etc., also needn't worry to produce the color fringe of the image that the incident because of infrared light causes.
＜4. the effect of embodiment＞
At the iris apparatus of embodiments of the present invention with in having the video camera of this iris apparatus, be suitable for like that as described outside the shooting at night etc. of the less light quantity of requirement and necessary exploring degree, can side by side cut down the parts number and improve the characteristic such as shading value.The below discusses its reason.
At first, as the structure of iris apparatus 1, be formed with infrared intercepting filter layer 41 and ND filter layer 42 on filter sheet base plate 5.Therefore, compare with the situation that makes the ND optical filter be installed on aperture blades as parts independently as existing, can cut down the parts number.
In addition, as the structure of iris apparatus 1, be following structure: when making filter sheet base plate 5 enter on the light path of the light by aperture openings 43 incidents, ND filter layer 42 is concentric shape with aperture openings 43 and configures.Therefore, take in the situation that make aperture openings 43 form little aperture, become the state that not only ND filter layer 42 works effectively but also aperture openings 43 integral body are blocked by ND filter layer 42.Thereby even the state of little aperture, integral image also becomes uniform shading value.Therefore, improve the characteristic of shading value etc.
And, even in the situation that make aperture openings 43 openings must be larger than the state of little aperture, also seek to improve the characteristics such as shading value.Namely, make aperture openings 43 openings must be than the state of little aperture large operating state be applicable to environment such as the duskiness on daytime etc.Therefore, with the bright environmental facies on daytime than the time, the quantitative change of inciding the light of video camera gets quite few.Thereby, even aperture openings 43 is open greater than the formation of ND filter layer 42 zone, if with the bright environmental facies ratio on daytime, the difference of the light and shade that causes because of the existence of ND filter layer 42 also diminishes extraordinarily.In addition, even the size of aperture openings 43 is due to a pair of aperture blades 3,4 relatively move and change, the position of ND filter layer 42 is also constant, and therefore, the center of shading value can be not inclined to one side.Therefore, consist of with the knot that respectively the ND optical filter is installed on a pair of aperture blades as existing iris apparatus and compare, improve the characteristics such as shading value.
And, in the situation that existing iris apparatus, when making aperture openings open gradually from the state of little aperture, the light by aperture openings is divided into light by the intersection of 2 ND optical filters, by the light of any ND optical filter, these 3 light of part light by the ND optical filter not.With respect to this, in the situation that the iris apparatus of present embodiment, be defined as the light of the part (middle body of aperture openings 43) by ND filter layer 42, these two light of light by the part (peripheral part of aperture openings 43) beyond the part of ND filter layer 42 by the light of aperture openings 43.Therefore, the light and shade different deviation that distributes is suppressed.Thereby the effect of the raising of the characteristics such as shading value becomes more remarkable.
In addition, the reduction along with above-mentioned parts number also can obtain following effect.Namely, in the situation that make iris apparatus 1, do not need the ND optical filter is installed on the operation of aperture blades.In addition, in the situation that with bonding agent, the ND optical filter is pasted on aperture blades, the gap that a pair of aperture blades of thickness phase Calais's setting of the thickness of ND optical filter (example as, Approximately 0.1mm) and bonding agent need to be relatively moved.With respect to this, in the situation that ND filter layer 42 is formed at filter sheet base plate 5, its thickness is just enough about a few μ m～tens μ m.Therefore, can seek the slimming of iris apparatus 1.And in the action of iris apparatus, it is mobile that aperture blades repeats continually, therefore, utilizing during bonding grade is pasted on the ND optical filter iris apparatus that aperture blades forms, and the ND optical filter might be because coming off along with the vibration of the movement generation of aperture blades etc.With respect to this, in ND filter layer 42 being formed at the iris apparatus that filter sheet base plate 5 forms, can not produce such unfavorable condition.Thereby, can realize the iris apparatus of the reliability excellence of long-term action.
In addition, as the structure of filter sheet base plate 5, the optical attenuation zone that is made of ND filter layer 42 forms circle.Therefore, even the opening shape when aperture openings 43 becomes little aperture is polygon, ellipse for example, as long as beyond be cut in this opening shape the following circle of diameter of a circle form the optical attenuation zone, although the difference of this opening shape also can improve the characteristics such as shading value.Therefore, become the iris apparatus of versatility excellence.
In addition, particularly, as preferred example, also can adopt the structure that forms the optical attenuation zone with the shape similar to the opening shape of aperture openings 43.For example, when a pair of aperture blades 3,4 is overlapped, the existence of the barbed portion of the shape of the aperture openings 43 that is formed by hole section 15 and bend 18 by utilizing V font separately becomes in the situation of quadrilateral (rhombus), also can be in advance the optical attenuation zone be formed the shape similar to it.
In the situation that adopt this structure, take for little aperture carries out colour in the situation that make aperture openings 43, keep the state of blocking aperture openings 43 with ND filter layer 42, until the physical dimension in the formation zone of the opening size of aperture openings 43 and ND filter layer 42 is consistent.The formation zone that therefore, can make ND filter layer 42 is flexible Application to greatest extent lavishly not.In addition, can make the formation zone of ND filter layer 42 be limited to Min. thereupon.Therefore, can be suppressed at the reduction of the light quantity that makes the open situation of aperture openings 43 under colored screening-mode as far as possible.
In addition, in the situation that make aperture openings 43 open greatlyr than the state of little aperture, the zone (below be designated as " the non-zone that forms ") that is not formed with ND filter layer 42 is present in the complete cycle of the outer edge part of aperture openings 43 equably.Therefore, in the open area of aperture openings 43, be arranged in the wherein formation zone of the ND filter layer 42 of centre section, image is relatively dimmed, and in the non-formation zone of ND filter layer 42, it is bright that image becomes relatively.With respect to this, normally central portion brightens lens for shooting, what are dimmed for circumference.Therefore, can make by cancelling out each other of they the shading value homogenising of image.
In addition, on the formation of filter sheet base plate 5, be formed with infrared intercepting filter layer 41 and ND filter layer 42 with stacked state on the same first type surface of glass substrate 40.Therefore, in the situation that make filter sheet base plate 5, do not make glass substrate 40 table back of the body upsets just can form (film forming) infrared intercepting filter layer 41 and ND filter layer 42 with the order of infrared intercepting filter layer 41 and ND filter layer 42.
＜5. variation＞
Protection scope of the present invention is not limited to above-mentioned embodiment, in the scope of the specific effect that constitutive requirements and the combination thereof of deriving by invention obtain, also comprises the form of having carried out various changes, improvement.
For example, for ND filter layer 42, also can not be formed in a first type surface of glass substrate 40, and be formed in the first type surface of a side opposite with the first type surface that is formed with infrared intercepting filter layer 41.In addition, for infrared intercepting filter layer 41 and ND filter layer 42, also can be respectively formed at two first type surfaces of glass substrate 40.And, shape as the plane in the optical attenuation zone that is consisted of by ND filter layer 42, be not limited to the shapes such as described circle, can be also for example to belong to polygonal triangle, quadrilateral, pentagon, hexagon, (following omission), can be also shape, for example star in addition, petal-shaped, cruciform, cloud shape, semilune.
In addition, the lamination order in the time of also infrared intercepting filter layer 41 and ND filter layer 42 can being layered in glass substrate 40 with the order opposite with above-mentioned embodiment form infrared intercepting filter layer 41,, infrared intercepting filter layer 41 is covered the state formation infrared intercepting filter layer 41 on ND filter layer 42.

In addition, also can be following structure: for the action of switching the filter sheet base plate 5 that screening-mode carries out be not as above-mentioned embodiment with the spinning movement at bolster 35 centers, for example the shift action of the slidingtype by straight line carries out.In the situation that adopt this structure, adopt following structure to get final product: for example, the first type surface zone of rectangular substrate is divided into two zones on the length direction of this substrate, only be formed with the infrared intercepting filter layer in a zone, and section is formed with the ND filter layer in the central.
In addition, structure as the filter sheet base plate 5 with infrared ray cut function, be not only limited to and as above state embodiment be formed with like that the structure of infrared intercepting filter layer 41 on glass substrate 40, can be also for example glass substrate 40 self have the ultrared function of blocking structure, that is to say, can be also the structure that adopts the glass substrate 40 that is consisted of by infrared ray cut glass.
In addition, structure as the filter sheet base plate 5 with ultraviolet cutoff function, being not limited to be made of ultraviolet cutoff glass the structure of glass substrate 40 as above-mentioned embodiment, can be also the ultraviolet cut filter layer to be formed at the structure of the first type surface of glass substrate.
In addition, also can adopt ND filter layer 42 is formed at thin film base material, this film base material is sticked on the structure that glass substrate 40 forms.
In addition, on the formation of iris apparatus of the present invention, for " visible light is by the zone ", this visible light is the zone that visible light is passed through by the zone, more specifically, make zone that visible light passes through, further specifically with the state of the light of having removed the presetted wavelength territory, the unwanted light of shooting of video camera can be removed in the zone that visible light passes through under the condition of visible light.The shooting of the video camera of this situation unwantedly only refer at least one light in " light that the wavelength ratio visible light is long " and " light that the wavelength ratio visible light is short ".More specifically, at least one light in infrared light (comprising near infrared light) and ultraviolet light (comprising black light) is equivalent to " the unwanted light of shooting of video camera ".
Thereby, also can there be the situation of the function that only has infrared intercepting filter in " visible light by zone " that filter sheet base plate 5 has or only has the situation of the function of ultraviolet cut filter except the situation with these two optical filter functions of infrared intercepting filter and ultraviolet cut filter.But, on the basis of the color fringe that prevents image, preferably have the zone of these two optical filter functions of infrared intercepting filter and ultraviolet cut filter.In addition, by the zone, may not make the whole zone on the first type surface of glass substrate 40 is that visible light passes through the zone for visible light, guarantees that in the mode that becomes the zone larger than the optical attenuation zone visible light gets final product by the zone.
