Request InfoIDEX Health & ScienceMelles Griot Optics Group has released additional Fizeau interferometric test optics to complement its line of Absolute Fizeau λ/40 transmission spheres. The Absolute Fizeau λ/50 concave and convex reference spheres will enable users to record and store reference wavefronts for subtraction from interferometric test data. The Absolute Fizeau λ/50 transmission flats will enable them to increase the 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...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra December 2022 IssuePhotochemical Reactor SystemThe LightSyn Lighthouse from Asynt Ltd. is a photochemical reactor system developed for high reaction yields, ease of use, operational safety, and competitive pricing.
