I am trying to calculate glazing transmssivity for window glass with a measured transmittance of 0.44. I have tried to use the formula on the rayfront website http://www.schorsch.com/rayfront/manual/dielectricdef.html but keep on getting a strange answer 0f -320. Does anyone know if this formula is correct or how to calculate transmissivity?
Cheers
Ben Masters
Dear Ben,
the formular equals the formular in the tutorial and is correct. (We use
it since years and you can also check it with virtual tranmittance
measurements.)
The transmissivity value should be .479807.
