ABSTRACT:
The invention relates to a cell for an ophthalmic lens, for testing the latter with an optical inspection system, said cell comprising a hollow space (11, 31) which is filled with a liquid and has an axis (12, 32) coinciding, in the test position, with the optical axis of an inspection system and, in the test position of the cell, is delimited from above by a viewing glass (13, 33) for the optical test and has, underneath the viewing glass, a test trough (14, 34) for the ophthalmic lens. Between viewing glass (13, 33) and test trough (14, 34), at least one insertion channel (15, 35) opens into the hollow space (11, 31), the ophthalmic lens being able to be inserted into the hollow space (11, 31) through the outer insertion opening (16, 36) of said insertion channel (15, 35)
