Pellin-Broca Prisms

Knight Optical supply custom pellin-broca prisms that cover the UV visible and NIR range. Custom pellin-broca prisms have one 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 the prism.

Our custom UV fused silica version has its input and output faces at brewster’s angle for a wavelength of 240nm. This gives a very high transmission for correctly polarised light.

Knight Optical supply high quality custom Pelin-Broca prisms made to your custom specification. Every component is individually tested by our highly skilled technicians in our state of art metrology lab to ensure all components meet our high quality standards.

Contact our multilingual technical sales team and discover how Knight Optical’s high quality Pelin-Broca prisms and service can improve your instrumentation and supply chain experience.
