Verifire Asphere+ Brochure

The Verifire Asphere+ (VFA+) system enables precise asphere metrology by leveraging Fizeau interferometry — a long-proven method of high-precision and high-resolution optical metrology. It produces full aperture measurements at very high resolution, enabling polishing feedback of the entire optic surface.

The VFA+ provides a flexible metrology platform to measure a range of axisymmetric aspheres with only a change of the transmission sphere. The VFA+ is equipped with an optional secondary stage which supports a computer generated hologram (CGH) extending the asphere shape capability to nonsymmetric freeforms and off-axis aspheric optics.
