AccuFiz Infrared
Compact, high value Fizeau interferometers for infrared IR measurements.
High performance, quality and value, for accurate, repeatable measurement of surface shape and transmitted wavefront quality.
Measure IR optics and systems at 1.053–1.55 micron wavelengths
AccuFiz infrared interferometers provide accurate measurement of IR optics and precision surfaces. AccuFiz infrared laser interferometers are ideal for measuring concave, convex and afocal IR components, as well as infrared telescopes and lens systems. Their ability to capture high slopes makes it possible to measure aspherical optics without the need for a holographic element.
AccuFiz IR interferometers are loaded with standard features, such as a touch-screen remote and fully motorized controls. Optional dynamic measurement mode lets you measure despite vibration and air turbulence, without an air table. Only AccuFiz includes Smart Zoom™ to ensure accurate lateral resolution over the entire 1X–10X zoom range. Diffraction-limited imaging provides unparalleled resolution, particularly at mid-spatial frequencies, to measure polishing artifacts that other interferometers miss.
