AccuFiz Visible and NIR Fizeau Interferometers

Compact, high value Fizeau for shop-wide optics measurement.

An unmatched combination of performance, quality and value, for accurate, repeatable measurement of surface shape and transmitted wavefront quality. 

AccuFiz Fizeau Interferometer

AccuFiz Visible and NIR Fizeau Description

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.

AccuFiz Fizeau Interferometer with Surface Isolation Source for measureing plane-parallel optics

Plane parallel optics

Surface Isolation Source option measures plane-parallel optics without coatings or back-surface treatment.

AccuFiz Fizeau Interferometer in horizontal mounting application

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

100mm or 150mm apertures

Optimized optical trains for 4 inch or 6 inch apertures. 

What to expect

AccuFiz 100mm (4 inches), 150mm (6 inches), and 300mm (12 inches) aperture systems are available as standard in the mainframe.

Aperture Converters are available to convert the 4 in. aperture to 150mm (6 in), 300mm (12 in), 600mm (24 in) and 800mm (32 in).

Unstabilized and stabilized sources are offered. Stabilized sources provide higher power and a longer coherence length which does not drift with temperature, simplifying long-cavity measurements.

Wavelengths in NIR are optional, versus the standard 632.8nm HeNe laser.
Table 1 shows the available AccuFiz models.
