Optical diffuser
Knight Optical

Knight Opticals' ground glass diffusers will scatter light at angles up to about 10°. They find applications in two main areas, firstly for focussing and secondly to enhance illumination uniformly in lighting systems. We stock two types of ground glass diffuser; borosilicate diffusers, which cover a range of 310 - 2700nm and UV silica ground glass diffusers which work down to 170nm in the UV.
