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.

AccuFiz Fizeau Interferometer Handheld Controller

Remote Control

Control the AccuFiz Fizeau interferometer with a touch screen device.

A dynamic Fizeau interferometer uses the polarization of light to measure all data simultaneously.

Vibration insensitive

Optional Dynamic Interferometry for measurement on the shop floor or in a clean room, despite vibration, without isolation.

Fizeau Interferometer mounts, optics and accessories

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.

Horizontal Mount

Vibration-free operation does not require an air table.

AccuFiz Fizeau Interferometer in look-down configuration (vertical stand)

Vertical Mount

Stands are available for look-down and look-up operation.

AccuFiz Fizeau Interferometer with 100mm aperture or 150mm aperture

Apertures from 100 mm to 800 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.
