Aspheric Lenses UV

UV fused silica aspheric lenses (Aspheric Lenses UV) are based on an aspheric element and are processed using advanced grinding and polishing equipment. UV fused silica aspheric lenses have a high numerical aperture (NA) of 0.65, which can provide optimal light gathering and focusing performance, and are very suitable for high-efficiency lighting applications or collimated broadband light sources, LEDs or similar light sources. UV fused silica also provides high transmittance in the UV band and a low thermal expansion coefficient, so it is very suitable for UV to near-infrared applications. The surface of the aspheric lens is optimized, using a more complex outer surface, and the curvature gradually changes from the center of the lens to the outside of the lens edge to reduce the spherical aberration. When focusing a collimated beam, it should be incident on the aspheric side of the lens, and when collimating the light from a point source, it should be incident on the lens plane, which can achieve the minimum spherical aberration.
