19 Jan 2007 Rochester, New York–The Melles Griot Optics Group today announced that they have released additional Fizeau interferometer test optics to complement their Absolute™ Fizeau l/40 transmission sphere product line. The addition of Absolute™ Fizeau l/50 concave and convex reference spheres will allow the user to record and store reference wavefronts for subtraction from interferometric test data, substantially improving their interferometer system's absolute accuracy. Absolute™ Fizeau l/50 transmission flats have been added to the product line to cost-effectively increase the absolute accuracy of Zygo® style Fizeau surface and wavefront-testing interferometers to l/50 without the need to store, manipulate, or subtract reference wavefronts during the testing process. New Absolute™ Fizeau l/50 reference flats have also been introduced to support applications requiring reference wavefront subtraction.
According to Dr. 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."
