Request InfoPhaseViewA digital wavefront sensor for laser beam profiling has been released by PhaseView. Without special hardware, the instrument measures both beam intensity and wavefront in every pixel with high resolution. Real-time measurements can be used to compute the beam’s waist, exact focal plane, propagation factor and divergence. The company also offers three analog sensors: Shack-Hartmann, lateral shearing interferometry and curvature. Applications include laser welding, focusing and free-space communications.See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 6/7/2022UHD HDMI to SDI Converter ModuleThe NA4K2022 small-form-factor UHD HDMI to serial digital video (SDI) converter module from eVision Systems GmbH provides native signal processing with high image quality.
