Knight Optical’s Littrow Prisms for Laser Applications

13 May 2021

Available as custom-made components to meet the precise needs of your end application, Knight Optical's premium-quality Littrow Prisms are a sought-after optic for engineers specifying for laser-based applications. They are commonly used close to the end of an optical cavity within a laser system to finely adjust the output frequency by changing the angle of incidence (AOI) of the prism.

At Knight Optical, we understand the importance of ultra-precision and the need for tailor-made solutions; particularly within high-precision laser-based applications. It's for this reason that we offer our Littrow Prisms as custom-made components for seamless integration with any device, regardless of size or requirements. This made-to-measure service allows you to specify the dimensions, substrates, tolerances and optical coatings – if required – that are best suited to your application.

Typical specs:

Material: SF11 (or equivalent), F2 (or equivalent), UV Grade Fused Silica

Dimensional tolerances: +/- 0.2mm

Angles: +/- 1 arcminutes

Surface figure: < 0.5 waves

Surface quality: < 40-20 Scratch/Dig
