[determination step of refractive index]
Measure an example of the determination step of the raw-material refractive index of lens for the apparatus for detecting refractive index 1 that uses this example, below will illustrate.
At first, the user in the upper end of the lens support 1013b of lensmeter 1000, measures the refracting power of the strong principal meridian direction of this tested lens L with tested lens L mounting.Obtaining of spherical degree S of strong principal meridian direction that the refracting power of tested lens L can be by calculating tested lens L and the measurement result of astigmatism degree C with S+C=D.This processing is carried out by the microprocessor of lensmeter 1000.The measured value D of the refracting power of tested lens L is stored in the storer of lensmeter 1000 for example.
Then, the user takes out a pair of mensuration member 100 from box (not shown).Measure on the binding face (the above-mentioned face that fits in tested lens L) of gelinite 110 of member 100 at each, stick in order to protect this binding face in order to avoid the release liners of generation dirt or damage it on.
The user operates operating portion 2A, 3A by finger, make the spacing of operating portion 2A, 3A become big, thereby make the spacing of measuring member maintaining part 2B, 3B become big, and, be installed on each that measure member maintaining part 2B, 3B measuring member 100 according to main points shown in Figure 3.Subsequently, tear release liners off from each gelinite 110 of measuring member 100.
, can after tear release liners off, will measure member 100 and be installed on mensuration member maintaining part 2B, the 3B, but when installation exercise, also have the possible of the binding face of making dirty herein, therefore after installation exercise finishes, can tear release liners off from gelinite 110.
And, when before mensuration member 100 is installed on mensuration member maintaining part 2B, the 3B, tearing release liners off, can not adhere to dirt in order to make on the surface plate 120, the user keeps linking frame 130 to tear release liners off by finger, but because it is little to measure the size of member 100, thereby it firmly can't be kept, cause measuring member 100 and may come off or be not easy to tear off release liners.On the other hand, if after mensuration member 100 is installed on mensuration member maintaining part 2B, 3B, tear release liners off, then can firmly keep operating portion 2A, 3A, thereby can reduce and measure the possibility that member 100 comes off, and the operation that tears release liners off is carried out easily by finger.
After tearing release liners off, between the mensuration member 100 that tested lens L is configured in measure member maintaining part 2B side and the mensuration member 100 of mensuration member maintaining part 3B side from gelinite 110.Then, operating portion 2A, 3A are operated, the spacing of measuring member maintaining part 2B, 3B is narrowed down, so that the binding face of the gelinite 110 of the mensuration member 100 of mensuration member maintaining part 2B side is close to the Surface L a of tested lens L, and the binding face of the gelinite 110 of the mensuration member 100 of feasible mensuration member maintaining part 3B side is close to the back side Lb of tested lens L.
At this moment, spring 5 is on the direction of the lens face of pushing tested lens L, to the binding face application of force effect of both sides gelinite 110.Can remove the binding face of gelinite 110 and the bubble between the lens face thus, gelinite 110 and lens face are suitably fitted.And when having bubble between gelinite 110 and the surface plate 120, this bubble also is removed.In addition, operating portion 2A, 3B are operated,,, also can strengthen removal effect thus bubble to gelinite 110 application of forces of both sides with on the direction of pushing tested lens L.
And the acting force of spring 5 also plays the fit-state of keeping the gelinite of suitably fitting for the time being 110 and lens face.Thus, even if for example the user no longer continues the application of force on the direction that the spacing that is made mensuration member maintaining part 2B, 3B by operating portion 2A, 3A narrows down, can prevent that also the gelinite 110 and the fit-state of lens face from worsening the state of affairs of (entering bubble etc.).Further, also can prevent to measure the offset of member 100, the state of affairs that perhaps tested lens L comes off with respect to tested lens L.
The user will be at the tested lens L under the state that is kept by mensuration member maintaining part 2B, 3B, and mounting is in the upper end of the lens support 1013b of lensmeter 1000.Subsequently, measure tested lens L on the strong principal meridian direction of tested lens L, with the synthetic refracting power that is close to the mensuration member 100 on above-mentioned two lens faces.The measured value D ' of synthetic refracting power is stored in the storer of lensmeter 1000 for example.
The microprocessor of lensmeter 1000 is with the measurement result D ' of the synthetic refracting power of the refracting power measured value D of tested lens L, tested lens L and two mensuration members 100 and the refractive index n substitution following formula of gelinite 110, with the raw-material refractive index N of the lens that calculate tested lens L.
[several 1]
N = n × D - D ′ D - D ′
Microprocessor is kept at the result of calculation N of the raw-material refractive index of lens in the storer, and is shown on the display frame 1003a.By the above, use the mensuration of 1 pair of raw-material refractive index of lens of apparatus for detecting refractive index to finish.
After measuring the end of job, the user will be taken off from lensmeter 1000 by tested lens L that apparatus for detecting refractive index 1 kept etc., and operating portion 2A, 3A are operated, and make the pitch enlargement of measuring member maintaining part 2B, 3B, thereby take out tested lens L.Further, under the state that is being kept by each mensuration member maintaining part 2B, 3B, the user pastes release liners on the binding face of the gelinite 110 of measuring member 100.Subsequently, according to the main points opposite, will measure member 100 and from each mensuration member maintaining part 2B, 3B, take out and be received in the box with Fig. 3.
Herein, identical when tearing release liners off, also mensuration member 100 back stickup release liners can taken out, but release liners is sticked on the mensuration member 100 that is installed under the state of measuring member maintaining part 2B, 3B, can manage to prevent to measure coming off of member 100, and the sticking operation summary that makes release liners.
[effect, effect]
Below will its effect and effect be described to the apparatus for detecting refractive index 1 of this example with said structure.
Apparatus for detecting refractive index 1 uses for the raw-material refractive index of lens of utilizing mensuration member 100 to measure tested lens L, said determination member 100 comprises the gelinite 110 with known refractive index n, this gelinite 110 is close on each face of the Surface L a of tested lens L and back side Lb, and is transparent and soft.In addition, this apparatus for detecting refractive index 1 comprises: measure member maintaining part 2B, 3B, be used to keep two to measure members 100, make the binding face face-off of binding face and the gelinite 110 that is close to back side Lb of gelinite 110 of the Surface L a that is close to tested lens L; Arm 2,3 is used so that mensuration member maintaining part 2B, 3B relatively move, with the spacing between the binding face that changes two gelinites 110; And rotation axis 4.And, this apparatus for detecting refractive index 1 be provided with down used: by coming under the state of the tested lens L of clamping, carry out the mensuration of the refractive index of lensmeter 1000 by the gelinite 110 of measuring the mensuration member 100 that member maintaining part 2B, 3B kept.
According to apparatus for detecting refractive index 1 with said structure, also can will measure after member 100 is installed on the apparatus for detecting refractive index 1, directly do not keep this mensurations member 100, therefore can suppress dirt such as fingerprint attached on the mensuration member 100 by finger.And, can prevent because of adhering to the mensuration precision reduction that dirt causes.
In addition, owing to can be installed on the operation that tears release liners off under the state on the apparatus for detecting refractive index 1 or paste release liners measuring member 100, therefore can manage to make in the above-mentioned operation measuring the operation summary of member 100, and can suppress to carry out above-mentioned operation the time dirt such as fingerprint attached to measuring on the member 100.
Further, when the tested lens L mounting that mensuration member 100 will be installed is on lensmeter 1000, perhaps should tested lens L when lensmeter 1000 takes off, be not as discussed previouslyly to keep tested lens L itself with finger, but keep above-mentioned apparatus for detecting refractive index 1 (operating portion 2A, 3A) and carry out operation, therefore can manage to make above-mentioned operation simpleization.
The apparatus for detecting refractive index 1 of this example possesses two arms 2,3, and these two arms interconnect by rotation axis 4, and have operating portion 2A, 3A respectively, measures the front end that member maintaining part 2B, 3B are separately positioned on above-mentioned arm 2,3.And the user is by to the operation of operating portion 2A, 3A, and making two arms 2,3 is center and relatively rotating with rotation axis 4, can change thus respectively by the spacing between the binding face of measuring the mensuration member 100 that member maintaining part 2B, 3B kept.As mentioned above, because apparatus for detecting refractive index 1 has the form as scissors, so operability is good.
And, on this apparatus for detecting refractive index 1, be provided with spring 5, this spring on the direction that the spacing of measuring member maintaining part 2B, 3B is narrowed down to two arms, 2,3 application of forces, therefore can prevent the state of affairs that surface plate 120 and gelinite 110 or detected lens L and gelinite 110 peel off, thereby can manage successfully to measure.In addition, can manage to remove between gelinite 110 and the surface plate 120, reach the bubble between gelinite 110 and the tested lens L, and can prevent to form new bubble.
And, article two, arm 2,3 has following shape respectively: from be provided with measure member maintaining part 2B, 3B front end towards rotation axis 4, to with direction bending that other one arm deviates from mutually after, again to the direction bending that is close with other one arm, and two arms 2,3 can avoid the edge contact of tested lens L to arm 2,3.Thus, can sandwich tested lens L reliably by being installed in the mensuration member 100 of measuring member maintaining part 2B, 3B and measure.In addition, can manage to remove between gelinite 110 and the surface plate 120, reach the bubble between gelinite 110 and the tested lens L, and can prevent to form new bubble.
And measure member maintaining part 2B, 3B and comprise: the 1st keeps frame 21,31, is that the center is supported on each arm 2,3 freely to rotate with axle A1 (rotation axis 2a); And the 2nd maintaining part 22,32, be that the center is supported on the 1st maintenance frame 21,31 freely to rotate with an axle A2 (rotation axis 23,33) with axle A1 quadrature.Measuring member 100 is kept by the 2nd maintaining part 22,32.Thus, measuring member maintaining part 2B, 3B can move freely with respect to arm 2,3 respectively, and can freely change this mensuration member 100 gelinite 110 binding face towards.Therefore, can measure members 100 by 2 and sandwich this tested lens L reliably, and irrelevant with the shape of the lens face of tested lens L.In addition, can manage to remove between gelinite 110 and the surface plate 120, reach the bubble between gelinite 110 and the tested lens L, and can prevent to form new bubble.
Because the mensuration member 100 of this example possesses the structure that gelinite 110 is combined by linking frame 130 with surface plate 120, therefore can prevent that gelinite 110 from separating with surface plate 120, thereby can successfully measure operation.And, by this linking frame 130 gelinite 110 and surface plate 120 are close to, therefore can manage to remove the bubble between gelinite 110 and the surface plate 120, and can prevent to form new bubble.
In addition, by using gelinite 110 and surface plate 120, can carry out the clean-out operation of gelinite 110 and surface plate 120 simply and effectively with the linking frame 130 that mode removably combines.Moreover, as above-mentioned linking frame 130, for example can use by the linking frames that starting material constituted 130 such as elastic component such as rubber that can stretch.And, also can use linking frame 130 with the structure that can be separated into a plurality of (for example 2) part.
[variation]
Aforesaid structure only is in order to implement a concrete example of apparatus for detecting refractive index of the present invention preferably.Therefore, can in purport scope of the present invention, suitably be out of shape arbitrarily.Other enforcement aspects of apparatus for detecting refractive index of the present invention below will be described.
(variation of arm)
Fig. 9, Figure 10 represent an example of the form of arm in the apparatus for detecting refractive index of the present invention.In addition, in above-mentioned figure, omitted mensuration member maintaining part.
Apparatus for detecting refractive index 40 shown in Figure 9 comprises two arms 41 and 42, rotation axis 43 and spring 44.On arm 41, be provided with operating portion 41A, on arm 42, be provided with operating portion 42A.
