Compact, high performance Fizeau interferometers for shop-wide optics measurement at visible wavelengths.
An unmatched combination of performance, quality and value, for accurate, repeatable measurement of surface shape and transmitted wavefront quality.
The AccuFiz laser interferometer offers an unmatched combination of performance, quality and value, for accurate, repeatable measurement of surface shape and transmitted wavefront quality.
The AccuFiz is extremely easy to use in confined lab spaces. Its compact, lightweight design is extremely rigid for maximum stability in any orientation or environment.
In production environments as well as in the lab the AccuFiz provides industry leading repeatability. 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.

Optional Dynamic Interferometry for measurement on the shop floor or in a clean room, despite vibration, without isolation.
Full range of options and accessories
Designed for flexibility, the AccuFiz family includes a range of laser sources, aperture sizes, mounting components and accessories.
Plane parallel optics
Surface Isolation Source option measures plane-parallel optics without coatings or back-surface treatment.
Vibration-free operation does not require an air table.
Stands are available for look-down and look-up operation.
Apertures from 100 mm to 600 mm
Large aperture accessories include kinematic mounting. Use the AccuFiz for stand-alone operation, then return the instrument to the aperture converter to measure larger optics, with no need for re-alignment.
