AccuFiz Fizeau laser interferometer

4D Technology has announced that its new AccuFiz Fizeau laser interferometer offers high performance, quality and value for accurate shape and transmitted wavefront quality measurements.

AccuFiz provides accuracy at mid-spatial frequencies, letting users measure polishing artifacts. AccuFiz also includes a touch-screen remote, fully motorised controls and the company’s Smart Zoom feature for repeatable lateral resolution at all zoom settings.

A range of laser sources, aperture sizes, mounting configurations and accessories are available. Its optional dynamic interferometry feature lets users measure despite vibration and air turbulence without an air table.
