Not only is clear Perspex® lightweight and shatter-resistant, it boasts exceptional optical clarity. Perspex® Acrylic also offers 92-percent light transmission, which makes it more transparent than glass. Perspex® is also stronger than glass. Most cast acrylic offers 17-times more impact resistance than glass.
These additives can block this material transmission in certain ranges or modify its color. Transmission curves for specific materials can be found at the links below . Transmission was measured on 1-3 mm thick uncoated witness samples using a PerkinElmer Model 950 UV/VIS spectrophotometer.
With impeccable clarity, excellent weatherability, and high light transmission, this plastic has no additives to block the transmission of UV light. While UV filtering acrylic blocks up to 98% of UV rays, UV transmitting acrylic allows up to 92% UV ray transmission. Applications of UV Transmitting Acrylic
Anti Static Acrylic or ESD acrylic sheet offers surface resistance from 10^6 to 10^8 Ohms, standard size is 4x8ft, 1220x2440mm, thickness is from 1mm to 30mm.
Green laser protective, CE Certified, acrylic was tested. It blocked 100% on my IR meter (950 nm) with 30% VIS transparency (550nm). I then tested 16 colored standard acrylic sheets sold on Amazon (Red, blue, green, light green, yellow, etc.). The typical IR blocking was 4-5% with 95% of the IR energy of straight line radiation passing through. Contact lenses with various levels of UV protection are now available from brands such as Acuvue, Bausch & Lomb and CooperVision. Class 1 UV-blocking contact lenses claim to block 97% of UV-B and 81% of UV-A rays. But those claims convey a false sense of protection, eye experts say. “Contact lenses with UV-blocking technology may protect the 36,016. 4,719. physicsforlife said: OK, so people say that wearing white is better than wearing black in the sun because white reflects light whereas black absorbs light. But at the same time it is said that black is better for sun protection (for example, darker skinned people are much less likely to get skin cancer than lighter skinned people). M4JnjT.
