Aspheres Extreme Precision Aspheric Optics

Aspherical precision lens manufactured with Zygo's extreme precision aspheric lens manufacturing technologies.
Precision aspheres are manufactured with extreme
precision aspherical manufacturing technologies.
Aspheres – precision aspherical optics manufactured by Zygo Optical Systems Division – 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.
