Hello,
When specifying the Visible Light Transmittance of the glass, why does the input vary from the output (see image below)? Am I missing something?
Thanks,
Stefanos
Wlcome to the forum @stefpapathan ,
Be aware that the input is the Transmission of the material and the output is the Transmissivity.
According to Radiance reference, the equation to calculate the later is:
tn = (sqrt(.8402528435+.0072522239TnTn)-.9166530661)/.0036261119/Tn
-A.
