Aspheric lenses can increase the numerical aperture of a lens while minimizing system aberrations. And it has advantages such as improving the system imaging quality, simplifying assembly,increasing the system reliability,etc. Aspheric lens is ideal for light collection, projection, illumination, detection, and condensing applications.
China Star Optics can provide customized high precision aspheric lenses and aspheric cylindrical lenses for laser and precision optical applications according to customer requirements. Aspheric products with diameters from φ5 to φ200mm, surface quality better than 20/10 and surface irregularity better than λ/4 are available on request.
China Star Optics offers high quality custom designed aspheric lens in any quantity from testing sample to mass production. Extremely small MOQ helps to reduce your initial project investment.
