Request Info4D Technology CorporationAccuFiz® IR laser interferometers operate at wavelengths of 1.55, 3.8 and 10.6 μm for accurate measurement of polished or rough-ground optics and metal surfaces. AccuFiz systems are ideal for measuring concave, convex and afocal IR components, as well as IR telescopes and lens systems. Their ability to capture high slopes makes it possible to measure aspherical optics without the need for a holographic element. Optional vibration-insensitive dynamic mode enables measurements under almost any environmental condition, without vibration isolation.See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Nov/Dec 2022 IssueBeam Profiling CameraThe Ophir SP504S Beam Profiling Camera from MKS Instruments Inc. measures large and divergent beams by accurately capturing and analyzing wavelengths from 340 to 1100 nm for beam sizes from 45...Photonics.com 4/15/2024AI 3D Vision SystemThe In-Sight® L38 3D Vision System from Cognex combines AI, 2D, and 3D vision technologies to create projection images for simplified training and revealing features not visible with traditional...Photonics.com 11/23/2023Handheld Laser RangefinderThe LMS-RF-NC-6025-NI-01 from LumiSpot Tech is an uncooled handheld rangefinder that uses infrared technology for target acquisition and images in both infrared and a color TV mode.
