File:Polycarbonate IR transmission.png

Summary
Transmittance in the NIR region for polycarbonate lenses (UVEX ultraspec goggles (path length of polycarbonate is ~ 2.3 mm)) taken using an Ocean Optics near IR (NIR-512) temperature-regulated InGaAs detector spectrometer. The wiggly region between 860 and 1060 nm is likely due to interference effects of a thin film coating on the plastic surface. Spectrum taken by me.
