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 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.
Control the AccuFiz Fizeau interferometer with a touch screen device.
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.
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.
