Transmission range graph

Useful transmission ranges for various plastics materials. Note that the wavelength scale is logarithmic. For acrylics, polycarbonate, and rigid vinyl in our standard thicknesses, the transmittance is greater than 80% in the indicated wavelength ranges. For POLY IR® materials in our standard thicknesses, average transmittance typically varies from 40% to 90% in the indicated wavelength ranges. For the POLY IR® materials, gaps in the ranges indicate the presence of strong infrared absorptions. Please see the information on the POLY IR® materials for more spectral details.
