Abstract

The invention relates to a cuvette for an ophthalmic lens, for testing the latter using an optical inspection system, said cuvette comprising a hollow space to be filled with a liquid and has an axis coinciding, in the test position of the cuvette, with the optical axis of an inspection system and, between a first viewing glass at the top and a second viewing glass at the bottom, a removable lens support is arranged in the lower area of the hollow space, so as to allow a free floating inspection of the lens at a defined inspection position when the lens support is removed.
