Request Info4D Technology CorporationA turnkey instrument designed for testing the next generation of Blu-ray, DVD and CD pickup heads has been announced by 4D Technology Corp. The WaveCam 1000 is a vibration-insensitive wavefront interferometer with a patented single-frame dynamic achromatic phase sensor. Operating with pulsed or CW sources, the device measures intensity and phase in collimated or divergent beams in as little as 30 µs. Its optics are coated and corrected for 780, 650 and 405 nm, the most common data storage wavelengths. The instrument provides zoom imaging and a turret mounting accessory that allows the optics...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 10/13/20233D Laser Line ProfilersThe Gocator® 2600 Series from LMI Technologies are 4K+ resolution smart 3D laser line profile sensors and can be used for applications in food processing, building materials, automotive, rubber...BioPhotonics Jan/Feb 2024 IssueUV-C Germicidal Radiometer KitThe UV-C germicidal radiometer kit from Gigahertz-Optik features the X1-UV-3725 radiometer, UV-3725-4 254 nm UV-C detector, UV-37xx-Z01 80° field of view adapter, and K-UV3725-S irradiance...Photonics Spectra January 2024 IssueMiniature Hand-Held VideoscopesThe TVGM Series from Titan Tool Supply are miniature, high-definition handheld industrial-grade videoscopes designed to support a variety of non-destructive testing and remote visual inspection...Vision-Spectra.com December 2023 IssueRobot Vision PlatformThe rc_visard NG from Roboception GmbH is an AI-driven robot vision platform.
