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 is a cur-
rent generated by the photodiode.
