The present invention provides an identification system for surgical cassettes (22), the system comprising: g) a surgical console (100) having a cassette receiving portion (110); h) a control system (10) having a plurality of light emitting diodes (18) and corresponding photodetectors (20) in the cassette receiving portion (110) of the surgical console; i) means for calibrating the control system comprising means for adjusting (12) the output of the light emitting diodes and means for measuring (14) a predetermined output received by the photodetectors; j) a cassette (22) insertable into the cassette receiving portion (110) of the surgical console, the cassette having a plurality of tabs (24), the tabs having variable opaqueness, such that when the cassette is inserted in the console, the tabs are adapted to at least partially block the light emitted by the light emitting diodes from reaching the photodetectors (20); k) means for increasing the output of the light emitting diodes (18) to a maximum; l) means (16) for measuring a relative opaqueness of the tabs (24) based on a relative variability of the amount of light reaching the photodetectors (20) through the tabs from the light emitting diodes when the light emitting diodes are at the maximum output, whereby in use the cassette (22) is identified based on the relative opaqueness of the tabs (24). <IMAGE> |
