T-1 PACKAGE
PIN PHOTODIODE
MID-30A12
Description
Package Dimensions
The MID-30A12 is a PIN photodiode mou-
nted in a lensed , special dark plastic package.The lens-
ing effect of the package allows an acceptance half view
angle of 10° that is measured from the optical axis to the
half power point .
