Request InfoIDEX Health & ScienceThe Melles Griot Optics Group has unveiled additional Fizeau interferometer test optics to complement its line of Absolute Fizeau λ/40 transmission spheres. The Fizeau λ/50 concave and convex reference spheres enable users to record and store reference wavefronts for subtraction from interferometric test data, resulting in improved accuracy of their interferometer systems. The Fizeau λ/50 transmission flats 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...See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Sep/Oct 2022 IssueMicrospectrophotometerThe FLEX PRO™ UV-VIS-NIR microspectrophotometer from CRAIC Technologies is a multifunctional tool able to acquire microscale images and spectra from the deep UV to the NIR.
