Aspheric Lens
Aspheric Lenses are precision lenses with a non-spherical surface profile, in which curvature varies from center to edge to correct spherical aberration within a single element. Chenyu Optics manufactures aspheric lenses in BK7, fused silica, optical glass and infrared materials, with custom focal length, diameter, surface quality and coating according to customer drawings.
Aspheric Lens Overview
Aspheric Lenses are precision lenses with a non-spherical surface profile, in which curvature varies gradually from center to edge to correct spherical aberration within a single optical element.
Compared with conventional spherical lens shapes, an aspheric profile can replace multiple spherical elements in an optical system, reducing element count, weight and assembly complexity while improving focusing and imaging performance.
Chenyu Optics supports custom aspheric lens manufacturing according to customer drawings, including custom material, focal length, diameter, thickness, surface quality and coating for prototype and repeat production.
