ROCHESTER, N.Y., June 16, 2006 -- Melles Griot Optics Group, a supplier of optical components and optical systems, has developed a family of high-precision Fizeau transmission spheres that quadruple the absolute accuracy of Zygo-style Fizeau surface and transmitted wavefront testing interferometers. The new 100-mm, clear-aperture transmission spheres are available from stock in f/0.76, f/1.5, f/2.2 and f/3.3.

The Absolute Fizeau transmission spheres enable companies to quadruple the performance of their existing interferometer systems at a very cost-effective price."
