3. Method of Operation The module houses a custom assembly, including multicolor sensors and a microprocessor. Separate optical cables that are comprised of a press fit plug connect to numbered ports on the module and a metal shrouded tip on the opposite end which is placed in front or on top of the LED to be tested. When a command for a specific numbered cable is sent to the module, the module will measure the color and/or intensity of the requested cable and send back the measurement via the chosen interface. Readings may be provided in either frequency (Hz) or in voltage (V) for the LED color...

Light- to- frequency converter sensors are comprised of an 8 x 8 array of photodiodes, 16 photodiodes each of blue, green and red filters and 16 photo-diodes of clear, with no filter. The micro controller, in combination with the precision MHz high frequency clock source, allows for extremely fast and accurate sampling of the light source under test. Fiber Optic cables The Mega FINNTM Module has two fiber optic options available – an 18” cable assembly and a 24” cable assembly. The smaller press fit plug end of the cable assembly fits into corresponding labeled socket in the top of the module...
