Light Transmission Versus Thickness
Light transmission decreases slightly with increased thickness
(see attached graph).
Optical Characteristics
Ultraviolet (UV) Radiation Blocking - PALSUN sheets completely
block out potentially harmful UV radiation and a significant
portion of Infrared (IR) radiation. Over the visible light range, a
typical 3 mm (0.125 inch) thick clear PALSUN sheet transmits
about 89% (average) of incident light, as seen in the attached
graph.
