MULTIPLEX LENS

摘要

PURPOSE:To position easily plural lenses with one operation and to improve the mechanical strength in the parts where the lenses are mounted by fitting the lenses into the plural fitting holes provided to a base body. CONSTITUTION:Lenses 13 are fitted into the stepped parts 12 of plural fitting holes 11 provided to a base body 10 consisting of a metallic plate, thereby constituting multiplex lenses 15. Hollow grooves 14 are formed at prescribed intervals on the surface of the plate 10 and the stress in the stage of mounting the lenses 13 is absorbed by the grooves 14. The deformation in the stage of mounting the plate 10 to a desired device is prevented as well. The plural lenses are thus easily positioned with one operation and the mechanical strength in the parts where the lenses are mounted is improved.
