Optical Diffusers

Thorlabs offers ground glass and engineered optical diffusers as well as diffuse reflectors. The engineered optical 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. Our ground glass optical diffusers are ideal for general purpose applications, whereas our engineered diffusers have a much more controlled diffusion.
