Request Info4D Technology CorporationThe PhaseCam MWIR is a dual-port, midwave infrared interferometer that measures optical surface shape and wavefront error at a 3.39 µm infrared wavelength with incredibly fast acquisition for vibration and turbulence immunity. Even when measurements are taken over long paths, in turbulence, or in vibration, the PhaseCam MWIR accurately measures critical optical parameters like transmitted wavefront error. These measurements provide validation of IR optical components in reflection or transmission, in system alignment situations, or for single optics. By measuring at wavelength, end...See full productRelated content from Photonics MediaPRODUCTSPromoted Content July 2022 IssueAccuFiz® D 600 mm interferometerDynamic, on-axis AccuFiz® D Fizeau interferometer with 600 mm beam expander measures large flat optics instantaneously, eliminating the need for controls on vibration or turbulence.
