De scrip tion
The OP993 photodiode consists of a PIN
silicon photodiode mounted in a dark
blue plastic injection molded shell
package. The wide receiving angle
provides excellent on-axis coupling. The
sensors are 100% production tested for
close correlation with Optek emitters.
Optek's packaging process provides
excellent optical and mechanical axis
alignment. The shell also provides
excellent optical lens surface, control of
chip placement, and consistency of
external package dimensions.
