Product Description

Optical Coated Monocrystalline Germanium Aspheric Lens for Manual Zoom Lens

Aspherical Lenses
Aspheric Lenses are used to eliminate spherical aberration in a range of applications, including bar code scanners, laser diode collimation, or OEM or R&D integration. Aspheric lenses utilize a single element design which helps minimize the number of lenses found in multi-lens optical assemblies. 
Products are widely used in optical equipment, teaching, industrial lenses, camera, video shooting, automation, medical, measuring and surveying equipment, aviation, astronomy, etc.. So it requires different materials for different work range.our products cover ultraviolet, visible light and infrared band.
