Additional information


With its diffraction-limited imaging system, the AccuFiz provides unparalleled accuracy at mid-spatial frequencies, letting you measure polishing artifacts that other interferometers simply miss.

The AccuFiz is loaded with standard features, such as a touch-screen remote, fully motorized controls and tool-free height adjustment. Smart Zoom™ ensures repeatable lateral resolution at all zoom settings.

Rugged construction, user-friendly 4Sight software and quality in every detail make the AccuFiz your new best choice for verifying optics and optical surfaces.
