Description
The OP950 device consists of a PIN
silicon photodiode molded in a clear
epoxy package which allows spectral
response from visible to infrared light
wavelengths. The wide receiving angle
provides relatively even reception over a
large area. The side-looking package is
designed for easy PC board mounting.
This photodiode is mechanically and
spectrally matched to Optek’ GaAs and
s
GaAlAs series of infrared emitting
diodes.
