Knight Optical (UK) Ltd Datasheets for Optical Diffusers
Optical diffusers scatter incident light, thereby reducing the sensitivity of a detection system to slight positional or angle changes in an incoming beam.

|---|---|
| A dome is an optical window composed of two parallel curved surfaces. Domes are commonly used in defence applications and often in extreme environments such as submersible ROVs. For this... | |
| Calcium Fluoride (CaF₂) is commonly used for optics looking at the IR and UV spectrums and has a very low change in refractive index with wavelength. It shares similar optical... | |
| Flashed opal offers a more thorough diffusion with a distribution close to Lambertian, with the brightness of the diffuser being independent of the viewing angle. Such wide scattering angles will... | |
| Germanium (Ge) is a relatively hard, high-density, IR transmitting material that blocks UV and VIS wavelengths but allows IR from 2µm. Germanium has the highest refractive index of commonly available... | |
| Gorilla® Glass Windows are chemically strengthened to provide excellent scratch resistance. These windows offer good performance in the visible range and due to it's strength, these windows can be offered... | |
| Highly durable, chemically resiliant and scratch resistant plastic diffusers from Knight Optical. Optolite™ HSR plastic diffusers offer superior, more uniform diffusion than ground glass and have a number of uses... | |
| Knight Opticals' ground glass diffusers scatter light at angles up to 10°. They are used predominantly in two applications; firstly for focussing and secondly to enhance illumination uniformly in lighting... | |
| Plastic screen diffusers provide superior diffusion to ground glass equivilents, and are both lighter, more flexible and offer wider shaping capabilities. Our PVC plastic screen diffusers are a cost effective... | |
| Quartz (SiO2) is a birefringent material commonly used in the manufacture of polarizers (such as wave plates) and windows. The material’s birefringent properties mean it has two refractive... | |
| Sapphire (Al2O3) is one of the hardest minerals and optical materials available for use in the range from UV up to 5µm. Sapphire is birefringent and... | |
| When two flat optical surfaces are in close proximity interference effects associated with residual Fresnel reflection can be seen, these are a special case of Newton’s Rings. Anti-Newton glass sheets... |
