Precision 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. As a precision aspheric lens manufacturer, Chenyu Optics manufactures precision polished aspheric lenses with custom diameter, focal length, surface accuracy and coating options, using single point diamond turning, precision polishing and molded aspheric manufacturing according to customer drawings, for imaging, laser and infrared optical systems.
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.
Chenyu Optics manufactures precision aspheric lenses using single point diamond turning, precision grinding and polishing, and molded aspheric manufacturing processes, selected according to material, tolerance and production volume requirements. This allows an aspheric profile to 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, covering both visible-range optics and infrared optical applications such as thermal imaging and laser systems.
