  • Trioptics Acquires µPhase from Fisba Optik
Jun 2010
WEDEL, Germany, June 18, 2010 — Optical test equipment maker Trioptics GmbH announced it 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. Financial terms were not disclosed.

Trioptics said the µPhase line complements its optical test equipment portfolio, which includes the TriAngle electronic autocollimator, OptiCentric cementing stations and WaveMaster wavefront sensors. Fisba will continue to produce uPhase's optical core components for Trioptics.

As part of the deal, Fisba Optik in Berlin will become part of Trioptics. Fisba Optik GbmH was established in 1998 by Fisba Optik AG to conduct optical metrology research and development. Fisba Optik AG said the transaction will allow it to further expand its business-to-business work in the photonics sector.

A single instrument combining the functions of a telescope and a collimator to detect small angular displacements of a mirror by means of its own collimated light. It consists of a lens with an illuminated reticle. The reticle usually carries several parallel lines subtending known angles at the lens. An electronic autocollimator provides a continuous output voltage, the sign and amplitude of which are related to the angular displacement of the mirror.  
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...
In a periodic function or wave, the segment of the period that has elapsed, measured from some fixed origin. If the time for one period is expressed as 360° along a time axis, the phase position is called the phase angle.
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
