De scrip tion
The OP905 device consists of a PIN
silicon photodiode molded in a clear
epoxy package which allows spectral
response from visible to infrared light
wavelengths. The narrow receiving angle
provides excellent on-axis coupling.
These devices are 100% production
tested using infrared light for close
correlation with Optek's GaAs and
GaAlAs emitters.
