4D Technology has announced the release of the new AccuFiz LWIR laser interferometer.
The AccuFiz LWIR laser interferometer enables measurement of aspherical optics without the need for a holographic element due to its ability to capture high slopes. It is for measuring concave, convex and afocal IR components, as well as IR telescopes and lens systems. The interferometer operates at a wavelength of 10.6um for an accurate measurement of polished and rough glass as well as metal. The IR wavelength enables measurement of rough-ground optics prior to the final polish. Available from Laser Physics UK, the AccuFiz LWIR laser interferometer can also be supplied with an optional, vibration-insensitive dynamic mode to enable measurements without vibration isolation or turbulence control.
