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 March 2024 IssueGlobal-Shutter Image SensorSTMicroelectronics’ global-shutter image sensor for smart computer vision can be used in AR/VR, personal and industrial robotics, drones, barcodes, biometrics and gestures, and embedded vision...Photonics Spectra September 2023 IssueMulti-Stage Thermoelectric CoolersThe OptoTEC™ MSX series of micro multistage thermoelectric coolers from Laird Thermal Systems Inc. allows integration into various optical packages.
