OptiCentric has been specifically designed to cover applications related to any type of optical component, including spherical and plano types, and to respond to different levels of required accuracy. The OptiCentric System also covers all the production steps starting with the measurement of centration errors and continuing with the alignment, cementing and assembly of optics. The OptiCentric System includes valuable tools for any application, from simple and affordable visual instruments to more complex, fully automated and PC controlled production and laboratory stations.

Comparison Goniometer

The Comparison Goniometer is a precision angle measurement instrument primarily used to measure prisms and other piano optical components in production environment. This instrument usually needs a reference prism with a known angle. The first reference measurement is done using the master prism. Further measurements are made relatively to the angle of the master prism. The results are given as difference to the master prism or as absolute value of the measured angle. 90-prism angles can be measured absolutely without the need of a master prism.


The PrismMaster is the first really automatic goniometer featuring accurate measuremets of prisms angles from 0 to360 either in reflection or in transmission. It incorporates an ultra-accurate rotary air bearing and a high precision rotary encoder whose cumulative error is within 0,2 arcsec or 0.5 arcsec.
