Transmission coefficients of sample materials [5].

MaterialTransmission coefficient

Single 4 mm glass or acrylic sheet0.850
Double 4 mm glass0.720
Teflon thin film0.950
Tedlar thin film0.900

Transmission coefficients of sample materials;all of thesecan be reduced by 1 or 2% due to dirt, up to 8% in dry dusty areas.
