ROCHESTER, N.Y., Jan. 3, 2007 -- The Melles Griot Optics Group, a provider of optical components, multielement lenses and contract-manufactured assemblies, has released additional Fizeau interferometer test optics to complement its Absolute Fizeau λ/40 transmission sphere product line.

AbsoluteFizeau.jpgThe company said the addition of Absolute Fizeau λ/50 concave and convex reference spheres allows users to record and store reference wavefronts for subtraction from interferometric test data, substantially improving their interferometer system's absolute accuracy.

Also added to the product lineup are Absolute Fizeau λ/50 transmission and reference flats that cost-effectively increase the absolute accuracy of Zygo-style Fizeau surface and wavefront-testing interferometers to λ/50 without the need to store, manipulate or subtract reference wavefronts during the testing process.

According to Bruce Capron, director of sales and marketing, “The new Absolute family of test optics will enable the interferometer user to quadruple the accuracy of their existing Fizeau interferometer. This should be of great interest to every optics house that wants to upgrade their test capabilities and increase the quality of the lenses that they produce.”
