Metrology System Implementation

Photonics Spectra
Jun 2010
QED Technologies of Rochester, N.Y., an exclusive provider of magnetorheological finishing and subaperture stitching interferometry, has announced implementation of one of its aspheric stitching interferometers at Leibniz Institute for Surface Modification (IOM) in Leipzig, Germany. The new interferometer will enable IOM to develop surface figuring and finishing steps that produce surfaces with accuracies in the nanometer range. The instrument will be used specifically for precision fabrication and measurement of aspheres.



GLOSSARY
interferometer
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...
interferometry
The study and utilization of interference phenomena, based on the wave properties of light.
