Photodiode
VISHAY
BPW21R is a planar Silicon PN photodiode in a hermetically
sealed short TO-5 case, especially designed for high
precision linear applications.
Due to its extremely high dark resistance, the short circuit
photocurrent is linear over seven decades of illumination
level.
On the other hand, there is a strictly logarithmic correlation
between open circuit voltage and illumination over the same
range.
The device is equipped with a flat glass window with built in
color correction filter, giving an approximation to the spectral
response of the human eye.
