Knight Optical’s Deviating Penta Prisms

17 Nov 2022

Commonly used for beam steering, range finding and surveying applications, our wide-ranging portfolio of Deviating Penta Prisms cover a range of wavelengths; from the visible through to the near-infrared (NIR) spectrum. 

With two surfaces used to reflect light, our premium quality Deviating Penta Prisms are offered in both stock and custom-made options. With an extremely tight deviation tolerance, our stock range of Deviating Penta Prisms have aluminised reflecting surfaces and are available manufactured from NBK7 (or equivalent). 

However, if you're looking for a more tailored approach to your optical specification, we also offer Deviating Penta Prisms as custom-made components, customised to your project's demands. This made-to-measure service allows you to specify the dimensions, tolerances, coatings and substrates that are ideally suited to your end application.
