Transmission in the ultraviolet range = nil.

Transmission in the visible range = 80%

Transmission in the IR range:

800 - 1400 nm wavelength = 70%
1800 - 2100 nm wavelength = 60%

1400 - 1800 nm = 20%
2100 + nm = nil

Watch out for that "dead zone" between 1400 & 1800 nm.

Cadillac plastices in Australia has an excellent web site. There's a
chart of transmittance vs wavelength at the bottom of this page:
