DESCRIPTION
The
SD138-11-31-211
device features
two silicon PIN photodiodes vertically
integrated a hermetic TO-5 package. The top
photodiode absorbs a portion of the light and
the remaining light is transmitted to the
bottom photodiode. The current ratio of the
two photodiodes is used to remotely
determine and monitor the color temperature
of an object.
The
SD138-11-31-211
can find
application in dual wavelength power meters
and remote color temperature sensing.
