Optical Diffusers

Thorlabs offers ground glass and engineered optical diffusers as well as diffuse reflectors and hexagonal light mixing rods. The ground glass diffusers are offered unmounted, mounted, and AR coated on N-BK7 substrates and unmounted on a UV fused silica substrate. Diffuse reflectors are available with either a UV enhanced aluminum or protected silver HR coating deposited on the surface. The engineered diffusers are offered unmounted and mounted on polymer and UV fused silica substrates. Our ground glass optical diffusers are ideal for general purpose applications, whereas our engineered diffusers have a much more controlled diffusion.
