Extreme Precision Aspheric Optics

Precision aspheres are manufactured with extreme precision aspherical manufacturing technologies. Aspheres - precision aspherical optics manufactured by ZYGO's Optics business segment - can be manufactured in sizes up to 500 mm, with tolerances better than λ/5000 RMS @ 633 nm.

In the digital age, aspheres are growing in popularity in modern optical lens designs. Aspheric surfaces can now be found in most IR designs, and are increasingly prevalent in the visible and DUV spectrum for a range of consumer, defense , medical and semiconductor applications. High end aspheric surfaces are also increasingly critical in lithography lenses.

ZYGO's Extreme Precision Optics team fabricates world-class aspheres and ultra-high precision aspherical optical assemblies, serving the Defense & Aerospace, Life Sciences, and Semiconductor markets.
