Ophthalmic lens centering device

摘要

An opthalmic lens centering device comprises a frame on which is a translucent first support plate which receives an opthalmic lens to be centered. There is a frosted screen at the base of the first support plate. A projector system above the first support plate projects an image of the ophtlalmic lens onto the frosted screen. A first observation channel and an opening in the frame enable an operator to view the frosted screen. A second support plate receives a template with which the opthalmic lens is to be compared. A second observation channel in conjunction with the same opening in the frame enables the operator to view the second support plate. The first and second observation channels have a common emergent section of which the opening in the frame forms part. There is a recess in the frame, opening onto its front surface, by means of which the second support plate is disposed at the front of the frame.
