PLEXIGLAS® SHEET COLORLESS: INFRARED LIGHT TRANSMISSION


INFRARED TRANSMITTANCE

Colorless Plexiglas® sheet sheet transmits most of the invisible near-infrared energy in the 700 to 2,800 nanometer region, but it also absorbs certain bands as shown. The curves for 0.118 inch and 0.944 inch thick colorless Plexiglas® sheet show that near-infrared transmittance depends on thickness, decreasing logarithmically as thickness increases.

At infrared wavelengths longer than 2,800 nanometers and as long as 25,000 nanometers, and in thicknesses greater than 0.118 inch, colorless Plexiglas® sheet is entirely opaque. At thicknesses less than 0.118 inch, Plexiglas® sheet transmits small amounts of infrared energy at certain wavelengths within this region. All standard formulations of colorless Plexiglas® sheet have the same general infrared transmittance characteristics.

Sensitive instruments confirm that weathering produces no change in the infrared transmittance characteristics of Plexiglas® sheet.
