Knight Optical (UK) Ltd Datasheets for Optical Prisms

Optical prisms are blocks of optical material with flat, polished sides that are arranged at precisely controlled angles to one another. They are used in optical systems to deflect or redirect beams of light. They can invert or rotate images, disperse light into component wavelengths, and separate states of polarization.

Product Name Notes
A dove prism has the interesting characteristic that if it is placed between a lens and the image formed by that lens then rotating the prism will rotate the image...
Amici Roof prisms also known as “Dach Prisms” or “Dachkanten Prisms” have two sections that meet at 90°. Roof prisms rotate a beam by 90° and at the same time...
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...
Corner cube prisms reflect the light back, nominally at the same angle at which they entered. These high-precision retro-reflectors offer excellent parallelism between the incoming and exiting beams. Corner cube...
Fresnel prisms are simple prisms but manufactured using the stepped surface approach of a Fresnel lens. Fresnel prisms must not be confused with fresnel rhombs or biprisms. We can offer...
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...
Homogenising light pipe rods provide uniform, homogenised illumination of non-uniform light sources through the process of total internal reflection. Hexagonal light pipe homogenising rods achieve about 35-40% increase on output...
Knight Optical supply a range of quality Zinc Selenide prisms either from stock or custom made to your specification. Every component is individually tested by our highly skilled technicians in...
Knight Optical supply a range of Rhomboid prisms from stock that cover the UV visible and NIR range. Rhomboid prisms displace a light beam laterally and in effect represent a...
Knight Optical supply deviating penta prisms that cover the visual and NIR range. The deviation prism is an optical component that will redirect a light beam into another known angle...
Porro prisms are variants of the standard 90° prism but used as a pair to displace and invert a beam. Porro prisms are widely used in binoculars where they orientate...
Right angle prisms are simply triangular blocks of glass with two 45° and one 90° angles. The precision grade right angle prisms have high surface quality and tight tolerance angles.
Right angle prisms are simply triangular blocks of glass with two 45° and one 90° angles. These precision UV grade fused silica right angle prisms have high surface quality and...
The Pellin-Broca prism has the very interesting property that the light at the required wavelength is deviated by 90° with the wavelength being selected by the angle of rotation of...
These dispersing equilateral dispersing prisms have a very simple triangular cross section. Equilateral dispersion prisms are commonly used for wavelength separations, i.e. refracting white light into a rainbow pattern effect.
These standard grade of right angle prisms are similar to the Precision grade versions but with easier surface quality and angular specifications. These standard range of right angle prisms are...
