Photonics Spectra
Sep 2010
Optical test equipment maker Trioptics GmbH of Wedel, Germany, has acquired the μPhase product line of interferometers from Switzerland-based Fisba Optik AG, along with Fisba’s Berlin-based business, Fisba Optik GmbH, effective June 30, 2010. Financial terms were not disclosed. Trioptics said the μPhase line complements its optical test equipment portfolio, which includes the TriAngle.

An instrument that employs the interference of lightwaves to measure the accuracy of optical surfaces; it can measure a length in terms of the length of a wave of light by using interference phenomena based on the wave characteristics of light. Interferometers are used extensively for testing optical elements during manufacture. Typical designs include the Michelson, Twyman-Green and Fizeau interferometers. The basic interferometer components are a light source, a beamsplitter, a reference...
