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 MediaPRODUCTSPhotonics Spectra November 2022 IssueTunable LaserThe T200S tunable laser from EXFO Inc. is a continuously tunable device for cost-optimized testing of transceivers and optical components in high-volume manufacturing.
