Request Info4D Technology CorporationThe AccuFiz 6MP Laser Interferometer provides the highest available resolution for measuring steep slopes, aspheric surfaces and small-diameter optics. Its 2400 × 2400-pixel sensor doubles the measurable spatial frequency range and quadruples the sampling capability of standard Fizeau interferometers. The added resolution makes it possible to measure surface shape earlier in the manufacturing process, to capture polishing marks despite high fringe counts, and to measure spherical/aspherical optics and molds with unprecedented accuracy.See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 8/3/2022Two-color Sandwich DetectorsTwo-color Sandwich Detectors from OSI Optoelectronics Inc. are designed for optical remote temperature measurements.
