ABSTRACT:
A system and method for inspecting an optical component such as a hydrated contact lens in which the system includes an illuminator providing light to a receptacle supporting the optical component with a saline solution and an imaging sensing device such as an eye or a video camera detecting fluorescent light generated in the optical component or in some portion of the receptacle and blocked by the optical component. The system and method are particularly useful for inspecting optical components which have been produced to have ultraviolet-absorbing properties.
