The PSS WS-7.56-TO5
Wavelength Sensor has two
p-n junctions constructed
vertically on a common
silicon substrate. The upper
diode has enhanced blue
and the lower enhanced red
response. Absorbed
radiation between 450 and
900 nm thus generates two
photocurrents proportional to
the wavelength of the
incident light. The quotient of
the signals is independent of
the light level up to the
saturation point. The
wavelength of impinging
monochromatic light or the
spectral density peak of
polychromatic light can
therefore be determined.
During photovoltaic operation (U
independence for Q (quotient of both the photo
currents) is expected for a radiation up to 150 µW. This
range can be increased up to 3 mW by operating
with bias voltage (U
