The Zinc Selenide window has a transmission factor of 0.96 meaning it transmits 96% of
the radiation before it gets to the camera. For correct temperature readings, that
transmission factor needs to be considered via setting the global emissivity value as a
composite correction factor in the camera’s software. For example, if the target emissivity
is 0.93, but the camera must look through the Zinc Selenide window with the transmission
factor of 0.96, then the global emissivity setting should be set to 0.89 to compensate for
both (0.93 x 0.96 = 0.89).
