Applications
·30ms single acquisition, 100ms single calculation: based on instantaneous phase-shifting technology, 4 interferograms are captured synchronously in a single frame, 5000 times faster than conventional interferometers, completely eliminating vibration and air turbulence interference. Nanometer-level accuracy guaranteed: surface form repeatability accuracy reaches <0.7nmRMS, meeting the extreme requirements of ultra-precision manufacturing. ·Shop-floor-level interference immunity: no vibration isolation table required, direct measurement under vibration, temperature difference and air turbulence conditions (e.g., next to machine tools, inside vacuum chambers). ·Lightweight design: compact system, even handheld installation possible; the fiber-optic measuring head supports remote inspection over hundreds of meters. Large-aperture expansion: upgradable to Φ800mm via a beam expander, covering ultra-large optics such as telescope mirrors and lithography lenses.
