Description

Both the HEDS-1200 and HEDS-1300 sensor are fully integrated modules designed for applications requiring optical reflective sensing. The modules contain an LED emitter (at the appropriate wavelengths) and a matched I.C. photodetector.

A bifurcated aspheric lens is used to image the active areas of the emitter and the detector to a single spot that defines the resolution of the sensor. The output signal of HEDS-1200 is a current generated by the photodiode.
