Request Info4D Technology CorporationThe PhaseCam 5030 Twyman-Green interferometer from 4D Technology Corp. was developed to remotely measure meter-class optics for terrestrial and space-based telescopes. Enabling measurement during vibration and air turbulence, the device employs Dynamic Interferometry to acquire all measurement data in one exposure. Fully remote-operated, the system can be mounted in locations such as measurement towers and environmental-testing chambers. It includes a high-speed optical phase sensor that eliminates the need for slow, piezo-based phase-shifters, permitting it to measure more than 10,000 times...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra February 2024 IssueUV-C LEDsThe line of 235 nm and 255 nm UVC LEDs from Marktech Optoelectronics can be used in both germicidal UV solutions and chemical and material sensing.
