Fused Silica Aspheric Lens
Fused Silica Aspheric Lenses are precision aspheric lenses in fused silica, a material with excellent UV transmission, low thermal expansion and high laser damage threshold, correcting spherical aberration within a single optical element. Chenyu Optics manufactures fused silica aspheric lenses, along with BK7, optical glass and infrared materials as applicable, with custom focal length, diameter, surface quality and coating according to customer drawings.
Fused Silica Aspheric Lens Overview
Fused Silica Aspheric Lenses are precision aspheric lenses in fused silica, a material with excellent ultraviolet transmission, low thermal expansion and high laser damage threshold, correcting spherical aberration within a single optical element.
Compared with standard visible-range optical glass, fused silica maintains high transmission and optical stability from the UV through the near-infrared, making it a standard choice for UV laser focusing optics and deep-UV imaging systems where a single aspheric element replaces multiple spherical elements.
Chenyu Optics supports custom fused silica aspheric lens manufacturing according to customer drawings, including custom focal length, diameter, thickness, surface quality and coating for prototype and repeat production.
