Hello there, I have been following the FLIR radiometry quick guide,
specifically the procedures for find the the window parameters in terms of
emissivity and temperature. Upon completion, I obtained values for my
Germanium window: tau=0.37 and WinTemp=207737.52. Has anyone else
followed the same tutorial with Germanium windows featuring AR/AR
coating? I would like to confirm if my calculations are in the vicinity
of realistic values

Just to update the case, my Tau calculations were wrong, the right transmission value is 0.94, very similar as the value given by the manufacturer. But I still have some dubs about the Window temperature.

What Lepton do you have? Is it definitely a radiometric one?
Just want to make sure what you’re doing is possible, before more people try to help out with solving the actual the problem!

Hi Andrew. I am using a Flip Lepton 3.5 with a Purethermal 2 board. I am attaching a text file with the values I am using for the calculation based on the Radiometry Quick Guide
