Which material absorbs the least UV radiation?

Glass is known for its ability to absorb very little ultraviolet (UV) radiation compared to other materials commonly used in optics. While different types of glass can vary in their UV absorption properties, standard glass typically blocks a significant amount of UV light, especially UVB and UVC rays.

Polycarbonate and Trivex are both high-performance materials that are designed to provide impact resistance and optical clarity, but they generally allow more UV radiation to pass through than standard glass, although they are often treated with coatings that enhance UV protection. Plastics, similarly to polycarbonate and Trivex, can have variable UV absorption properties and may not provide as much inherent UV protection without additional treatments.

This combination of factors underscores why glass is often preferred in applications requiring minimal UV exposure, such as in certain lenses and protective barriers, making it the material that absorbs the least UV radiation among the given options.
