Amber glass can offer optimal protection against harmful UV light because it can absorb nearly all light wavelengths below 450 nanometers. It can also block blue light. That is why it is the most ideal material for packaging light-sensitive products.
Does acrylic plexiglass block UV light? Although UV filtering plexiglass can not completely prevent colors from fading or darkening, it does filter out up to 98% of harmful UV light. The UV protection of this acrylic sheeting only blocks UV wavelengths shorter than 400 nanometers.
Look at side of thru plastic layer. change sides of panel. The UV side is the side where the plastics glows the most. The Non UV side will not glow much at all. Think a 365 nm would do better since the sheets reject UV beginning at 400 and the 395 nm flashlights have some output to at least 425 nm.
Commonly used impact resistant polycarbonate (PC) safety glasses were evaluated for suitability of use in a high power, ultra-violet (UV) laser lab in place of laser eyewear. Product bulletins for the glasses tested all specified 99.9% or greater UV absorbance for their PC materials. Safety glasses from various manufacturers were exposed to
