AccuFiz Fizeau Infrared Interferometers

Compact, high value Fizeaus for SWIR and LWIR measurements.

High performance, quality and value, for accurate, repeatable measurement of surface shape and transmitted wavefront quality.

IR Laser Interferometer - AccuFiz SWIR Fizeau Infrared Interferometer

Measure IR optics and systems at 1.55—10.6 micron wavelengths

AccuFiz Infrared Fizeau Interferometers

AccuFiz infrared interferometers provide accurate measurement of polished or rough-ground optics and metal 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, 2X discrete zoom and fully motorized controls. Optional Dynamic mode lets you measure despite vibration and air turbulence, without an air table.
