Request InfoMahr Inc.PROVIDENCE, R.I., Oct. 19, 2017 — The MarOpto MT 100 Fizeau Interferometer Measuring Tower from Mahr Inc. is a high-precision, low-cost interferometer for measuring spherical and plano optics on the shop floor. MarOpto MT 100 is ideally suited to precision optics production up to 4 in. in diameter. Spheres and flats can be measured with λ/20 accuracy and the Z axis covers 800 mm at a resolution of 0.5 µm for precision determination of the radius in the optic under test. Besides tests of form deviation, towers with scales can measure radii with high accuracy. Motorized axes allow easy and fast operation and...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 4/27/2023Optical Time Domain ReflectometersThe D-Series of Optical Time Domain Reflectometer (OTDR) solutions from EXFO are advanced field testing tools that deliver highly accurate measurements to characterize and validate fiber links. ...Photonics.com 6/8/2022On-axis Dynamic InterferometerThe AccuFiz® D on-axis dynamic interferometer from 4D Technology Corp. features a 600-mm aperture beam expander, measuring remote cavities, optical thickness, and homogeneity, even in challenging...Photonics Spectra September 2022 IssueFizeau InterferometerThe AccuFiz® Fizeau interferometer from 4D Technology Corp. now features a 9-MP camera for higher slope tolerance through superior spatial resolution.
