Circular Optical Diffusers

The 10DIFF-VIS Flashed Opal Optical Disk Diffusers is significantly less expensive than integrating spheres and is easily mounted in a simple optic holder. Diffusers scatter incident light, thereby reducing the sensitivity of a detection system to slight positional or angle changes in an incoming... [See More]

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 are lightly etched to deform the surface enough to prevent this but with minimal effect on... [See More]

Calcium Fluoride (CaF ₂) 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 properties with Barium Fluoride although it has a transmission that is 2.5 µm less into the infra-red. Calcium... [See More]

Germanium (Ge) is a relatively hard, high-density, IR transmitting material that blocks UV and VIS wavelengths but allows IR from 2 µm. Germanium has the highest refractive index of commonly available IR-transmitters and has low optical dispersion. This makes it desirable in aspects of lens... [See More]

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 in very thin options whilst still maintaining it's protective function. Gorilla ®...

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 systems. We stock two types of ground glass diffuser; borosilicate diffusers that cover a... [See More]

Sapphire (Al2O3) is one of the hardest minerals and optical materials available for use in the range from UV up to 5 µm. Sapphire is birefringent and if its use is for critical optical application then the crystal might have to be cut along the zero degree plane, or C-Cut. Random cut is usually... [See More]
