Prisms & Angles


Knight Optical are proud to own a Trioptics PrismMaster for measurement of prism angles and parallelism. The Trioptics PrismMaster is a high speed electronic autocollimator with an ultra precise motorized rotating bed, allowing us to fully automatically measure angular specifications on prisms, beamsplitter cubes, windows and polygons.

Our comprehensive measurement and analysis software allows customized procedures to be created to save time when tested repeat orders and automatically generates reports and certificates.

Angular data is always supplied in the part’s detailed metrology report alongside the relevant tolerances. Metrology reports can be adapted to suit your needs. Contact our technical sales team to find out how we can help you.
