The present invention provides a surgical cassette (22) adapted to be received by a surgical system, the cassette comprising a housing (23) and a plurality of identification tabs (24) projecting from the housing. The tabs are variably opaque to translucent, such that by varying the transmissibility of light through the tabs in a predetermined manner, the number of distinctly identifiable cassettes (22) may be increased without increasing the number of identification tabs (24). The surgical system (10) uses an arrangement of light emitting diodes and photodetectors to identify a cassette inserted therein. <IMAGE> |
