面１ａよりも上方に位置する。The light-blocking member 2 is attached to the main body 1 by inserting the cylindrical mounting portion 10 of the light-blocking member 2 into the first through hole 5 of the main body 2 from below. The upper end surface 10 a of the mounting portion 10 is located above the upper surface 1 a of the main body 1.

実用上不便である。The light blocking member 2 shown in FIGS. 1 to 3 has a disk-shaped base 2a having a diameter about 1 mm or more (preferably 1 to 5 mm) larger than the entire length L of the intraocular lens 31 in FIG. doing. If the total length L of the intraocular lens 31
If it is not larger than 1 mm (less than 1 mm), it will overlap with the shape of the intraocular lens, and the inspection cannot be performed. On the other hand, if it is larger than 5 mm,
Inspection of the intraocular lens is possible, but the whole inspection jig becomes large, and accordingly, the whole inspection device becomes large,
It is practically inconvenient.

(H is 1 to 6 mm, preferably about 3 mm). The mounting portion 10 is supported by the support portion 33 (see FIG. 6) at the time of inspection by the automatic projector inspection device 41 shown in FIG.
It is necessary to remove the shadow of

周像がより正確にえられ、好ましい。As shown in FIG. 4, if a tapered portion 10b that narrows upward is provided inside the cylindrical mounting portion 10, the intraocular lens can be mounted on the mounting portion. It is preferable that the outer peripheral image of the intraocular lens be obtained more accurately when it is placed on the upper end surface 10a of the lens 10.

If it is less than 1 mm, the image of the outer peripheral shape of the intraocular lens is blurred by the light reflected from the upper surface 1a of the main body 1, and accurate measurement cannot be performed. On the other hand, if it is larger than 6 mm, the stability of the intraocular lens is poor, and the size of the inspection jig is large, so that the entire inspection apparatus becomes large, which is practically inconvenient.

ましい。The pin 3 connects the intraocular lens to the upper surface 1a of the main body 1.
, At least about two (four in this embodiment) are provided on the upper surface 1a of the main body 1. By setting the four pins 3 concentrically, the intraocular lens can be aligned with the first through hole 9 of the main body 1 and the optical axis center of the optical section 32 of the intraocular lens 31. It is preferable that the outer diameter of the pin 3 is 0.5 to 2.0 mm because the processing is easy. Further, it is preferable that the height of the pin 3 is 1.0 to 4.0 mm higher than the height H of the mounting portion 10 because the lens 3 can be prevented from dropping due to vibration or the like during transport.
