Prisms and 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 and polygons. The PrismMaster is accurate to +/- 3 arcseconds and measures completely objective high accuracy part positions without operator input.

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.

Our PrismMaster is also used for parallelism testing to guarantee your product meets its angular specifications, even in laser-type applications with high (less than 10 arcsec) tolerances.

Angular data is always supplied in the part’s detailed metrology report alongside the relevant tolerances. For parallelism, data can be supplied either as the wedge angle in arcmins/arcsecs or as the variation of edge thickness in mm. Metrology reports can be adapted to suit your needs.
