Description
The OP954 device consists of a PIN
silicon photodiode molded in a clear
epoxy package which allows spectral
response from visible to infrared light
wavelengths. The very wide receiving
angle provides relatively even reception
over a large area. The side-looking
package is designed for easy PC board
mounting. These devices are 100%
production tested using infrared light for
close correlation with Optek’ GaAs and
s
GaAlAs emitters.
