The high-precision precision polished non spherical lenses of LightSense Intelligence are different from molded non spherical lenses in that they are processed using precision polishing. They can produce large diameter (≥ 10 mm) non spherical lenses with smaller surface errors. The surface of the non spherical lens has been optimized to adopt a more complex outer surface, and the direction gradually changes from the center of the lens to the outside of the lens edge through curvature to reduce spherical aberration. When focusing the collimated beam, it should be incident on the non spherical side of the lens, while when collimating the light emitted by the point light source, it should be incident on the plane of the lens to achieve the minimum spherical aberration.
Guangtan Intelligent provides high-precision and precise non spherical lenses with diameters ranging from Ø 10 mm to Ø 50mm, with a focal length range of 10-37.5mm, including uncoated and anti reflective coatings for VIS, NIR, and SWIR bands. The numerical aperture range is from 0.50 to 0.67, with a high numerical aperture that maximizes light flux while reducing spherical aberration. High precision non spherical lenses have an RMS 0.25 μ m non spherical surface shape error. Due to the small precision non spherical shape error, these lenses are very suitable for applications that require spherical aberration correction, including imaging applications and laser focusing applications. Guangtan Intelligent Technology provides spot products of high-precision and precision polished non spherical lenses.
