You can now quadruple the accuracy of your existing Fizeau interferometer at a very cost-effective price by using Melles Griot Absolute™ Fizeau λ/40 transmission spheres. These transmission spheres extend interferometer absolute accuracy to λ/40 @ 633nm or better.

Dr. Bruce Capron, director of sales and marketing for the Melles Griot Optics Group, states "We use the latest technology available, including subaperture stitching interferometry (SSI®) and magnetorheological finishing (MRF®), to provide the industry's best-performing test optics."

The 100-mm apertures are available from stock. These spheres are compatible with most standard bayonet-style mounts.
