Request Info4D Technology CorporationThe Vertical Digital Radius Slide from 4D Technology Corp. provides precise radius of curvature measurement of concave or convex optics. The slide provides axial positioning resolution to 1 μm for accurate measurement using 4D Technology’s AccuFiz compact laser interferometers. The device integrates with 4D Technology’s 4Sight data analysis software for fast, wizard-based radius of curvature measurement. The system can accurately measure the curvature without precise null at cat’s eye or confocal positions, resulting in increased accuracy and throughput.See full productRelated content from Photonics MediaPRODUCTSPhotonics 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.
