Description
Technical field
The present invention relates to a kind of rod lens array, a plurality of therein rod lens elements are arranged between two side plates and fill and cured resin in the space between this rod lens element, form this rod lens element with integral body, and a kind of method of making this rod lens element.Particularly, the present invention relates to a kind of rod lens array, by using glass reinforced epoxy that is used as side plate and the phenylol hardening agent that is used as epoxy curing agent, also have by using the addition reaction-type organic siliconresin, this organic siliconresin comprises the monodisperse spherical organic filler and its viscosity is adjusted, as the resin that is used to fill this space, this rod lens array improves arrangement, optical property and the against weather of lens element.
Background technology
As known in the art, rod lens array has a kind of structure, a plurality of minutes gradient index (minute gradient index) rod lens arrangement of parts are between two side plates in this structure, and potting resin is to be integral with each other between the gap in this lenticular unit, and this lens arra is the example of the optical element of the big image of the single continuous upright grade of formation.Because this rod lens array has short light path and do not need the inverted image mirror, therefore may realize making this device littler.The characteristics that reduce because of size, rod lens is often used as optical element, not only be used to form the image read system of image, such as fax, image reading apparatus, duplicating machine etc., also be used on photoreceptor, forming the image writing system of sub-image (latent image) according to the picture signal that provides.Recently, high resolving power is accelerated, and has improved to higher accuracy in the sub-image with about the requirement than good quality of the degree of accuracy of the position that forms the image place.
Usually, make this type rod lens array by method described in JP61-55610A.For example, on substrate, provide, and arrange the optical fiber lens element of predetermined quantity, with by using this sept as with reference to the one or more lines that form along substrate surface as the sept of arranging reference.After with this lens element of array format, interim sept is set, not disturbing this arrangement, and with another substrate as lid to push this lens element.In this case, resin is packed into the gap of lens element, to keep shape and to make optical property satisfactory.After this, be cut into predetermined lens length, and grind two cutting edge edges by the integrally formed block of lense of cured resin.
Here, glass optical fiber reinforced plastics (FRP) is used as side plate, and particularly, the glass reinforced epoxy plate is widely used in below the grinding (with reference to JP-A-2001-318208).
(a) essential is that the thermal expansivity of side plate is identical with the thermal expansivity of lens material, so that during heating treatment prevent the undesired structure of lens element behind potting resin.
(b) essential is that the grindability of side plate is identical with the grindability of lens material, because side plate must grind equally with lens element.
(c) material because of lens is a glass, thus can consider to use face glass, but because face glass damages easily, face glass is difficult to processing.
In this case, since after resin is filled and is solidified rod lens array by one by one from the block of lense cutting, so side plate must oil has the made of good thermal resistance.Therefore, in the prior art, use the hardening agent that produces glass fiber-reinforced resin plate to be restricted to anhydrides or thermotolerance amine, so that the glass reinforced epoxy plate stands about 200 ℃ processing.Moreover, if above-mentioned hardening agent is used, then behind resin solidification, implement calcination processing, with the quality of stabilized glass fibre strengthening epoxy resin board.For example, with about 200 ℃ of lasting tens hours enforcement calcination processing, the while is imposed load therein.
Yet, use the glass reinforced epoxy plate to be therein: the foreign matter that forms the water droplet shape in against weather test (moistureproof test) afterwards on the surface at lens element as the problem that the rod lens array of side plate has, and play the effect of lens, therefore, obviously reduced optical property.
In addition, the problem of existence is: the glass cloth of glass reinforced epoxy plate breaks away from from this panel, thereby has increased its surperficial unevenness, causes this lens element to arrange degenerating of degree of accuracy.
In addition, the problem that exists is: make handle in when the amido hardening agent is used as oxygenant the surface of glass reinforced epoxy plate be coated with by the bonding agent (cyanoacrylate) that uses and dye, and then high temperature heating and cleaning removing this bonding agent for a long time, thereby cause lower throughput rate.
Turn to be arranged on interpleural filler, the resin of filling in order to support the optical fiber lens element mutually comprises epoxy resin or organic siliconresin.For this resin, add the inorganic filler of ideal quantity to the there, the cutting performance when cutting to improve.In addition, the viscosity of this resin is than higher, and for example, 2500 to 3000mPas, and by the negative pressure potting resin.
In recent years, in order to form high resolving power and less irregular image, need to reduce lens diameter (for example, 0.6mm or still less).Yet if use the lens that use in the prior art, the problem that exists is that in small diameter lenses, the position of these lens or direction may be irregular (just, arranging performance are lowered).Owing to according to the lenslet diameter and gap smaller is difficult to resin is packed into this gap, limited available time, thickness during filling, thereby increased the viscosity impedance, so top problem may occur.When using epoxy resin,,, optical property is offset thereby being lowered and forming the position of image because the contraction quantity in the curing that increases has been disturbed lens arrangement.
Exist another problem to be, not with the resin complete filling in all parts, thereby cause optical property to descend.These problems may be caused that described poor flow properties is owing to high thixotropic and high viscosity, the gathering of inorganic filler or the obstruction of this resin of epoxy resin by the poor flow properties of resin.
In addition, because the high viscosity of resin, the gap with lens element of minor diameter becomes littler, expend this gap of long-time filling, and then workability is lowered.Since the adhering part of resin be unsuitable for lens element (glass) and substrate (FRP: fiberglass-reinforced plastic), so that the problem that exists is the bonding force of lens arra is not strong, so that the frequent bonding fault of appearance.

Embodiment
Fig. 1 is the skeleton view according to typical rod lens array 1 of the present invention.Assemble two side plates 10, face with each other, between this gap, insert two septs 12 to have a gap.A plurality of rod lens elements 14 are arranged on two lines of 10 of this side plates.Resin 16 is filled in the gap of lens element and is cured as whole assembling.The surface of this rod lens array 1 can be with conventional lenses identical.In the present invention, this side plate is made of glass reinforced epoxy, and the phenylol hardening agent is used as curing agent for epoxy resin.
When being used as curing agent for epoxy resin, the reason that lens performance obviously reduces is as follows at anhydride group hardening agent (for example, phthalic anhydride).Pass through the alkaline components reaction that airborne moisture extracts in the unreacted residue hardening agent that extracts by the moisture of air and the glass lens, thus with the formation compound and on lens surface generation water droplet shape foreign matter.In this, if be used as the hardening agent of glass reinforced epoxy as the disclosed phenylol hardening agent of the present invention, then because the difference of polarity, hardening agent not on the surface of lens the alkaline components in glass form compound.Therefore, the performance of lens does not have variation in against weather is tested for a long time.
In addition, according to bonding agent and glass reinforced epoxy panel bonding with and on the throughput rate that causes of stain (chemical reaction of amine and cyanoacrylate) reduce, this stain is produced by the amido hardening agent as curing agent for epoxy resin, this stain can be avoided by using the phenylol hardening agent, because top reaction does not have to take place because of polarity is different.
In addition, in the situation of using the phenylol hardening agent,, behind curing reaction, needn't implement calcination processing because stability is outstanding.If the evaporation and the transformation of resin then appear in the enforcement calcination processing, and then in the extreme case about this, occur becoming fragile, thereby peel off.Therefore, the volume of resin reduces, and then glass cloth breaks away from this surface, causes the tangible unevenness on this surface and the variation in thickness of increase.For this point, in the present invention owing to needn't implement calcination processing, thus unevenness that should the surface be unconspicuous and do not change, therefore improved the degree of accuracy of the arrangement of lens element.
In the present invention, the resin that is filled in this gap is the addition reaction-type organic siliconresin that comprises the monodispersed inorganic spherical filler of 0.1 to 20 quality %, and this inorganic filler has the average particulate diameter of 0.1 to 25 μ m.
Reaction during according to curing (polymerization), organic siliconresin is divided into condensation reaction type and addition reaction-type.The addition reaction-type of Shi Yonging is by the two keys of opening molecule and the polymeric type that adds another molecule therein in the present invention.Therefore, owing to can reduce the deviation of arrangement, the distortion of rod lens array 1 diminishes, and the deviation that can reduce the position that forms image.More specifically, cure shrinkage can be for 250ppm or still less.
Owing to prepare lens arra 1 by the cutting block of lense, so improved cutting performance by filler is added into resin.If the quantity of the filler of inserting is too little, then be difficult to improve cutting performance.Otherwise if the quantity of the filler of inserting is too big, the become membranaceous and substrate (FRP plate) of picture and the adhesive property of lens of this resin is lowered.As mentioned above, increase the filler of 0.1 to 20 quality % to the there.Inorganic filler has just been gathered and the obstruction of resin just occurs, by use organic filler prevent to stop up with non-filling fault be further possible.Particularly, by single dispersion, obstruction is prevented significantly.The example of single dispersion treatment is that silanization is handled.Possible is by silylating reagent being contacted with the organic granular surface as organo-silicon compound or the organoalkoxysilane (organoalkosysilane) that comprises three silicyls (triorganosilyl), suppressing agglomeration of particles.
Preferably, resinous principle and oily composition are added into organic siliconresin.By adding resinous principle, may improve the hardness and the intensity of resin, thereby the intensity of lens arra 1 becomes stronger.Resinous principle is trifunctional or four functional silicone compounds, and adds its 0.1 to 20 quality % (preferred 0.5 to 10 quality %).
