Infrared Aspheric Lens
Infrared Aspheric Lenses are precision optical components designed for infrared imaging and sensing systems. By using advanced aspheric surface profiles, these lenses reduce spherical aberration and improve optical performance across infrared wavelength ranges. Chenyu Optics manufactures infrared aspheric lenses in Germanium, Silicon, Chalcogenide Glass and ZnSe, uncoated or with MWIR AR, LWIR AR and custom infrared AR coatings, for thermal imaging, IR cameras and laser systems.
Infrared Aspheric Lens Overview
Infrared Aspheric Lenses are precision optical components designed for infrared imaging and sensing systems. By using advanced aspheric surface profiles, these lenses reduce spherical aberration and improve optical performance across infrared wavelength ranges.
Manufactured from infrared-transmitting materials such as Germanium (Ge), Silicon (Si), Chalcogenide Glass and ZnSe, infrared aspheric lenses provide high imaging quality, compact optical design and excellent infrared transmission. They are widely used in thermal imaging, infrared cameras, night vision systems, IR sensors and laser systems.
Chenyu Optics supports custom infrared aspheric lens manufacturing according to customer drawings, including custom diameter, focal length, aspheric profile, material and coating design for prototype and repeat production.
