Features
Aspherical lenses are lenses with a specially designed surface that can correct spherical aberration and improve imaging quality. Compared with traditional spherical lenses, aspheric lenses can better control the propagation direction and focusing effect of light.
Applications
In optical systems, aspheric lenses are widely used to eliminate spherical aberration, coma, astigmatism, distortion, etc. Compared with spherical lenses, aspheric lenses can achieve higher optical quality and imaging performance. Therefore, aspheric lenses have been widely used in some applications with high imaging requirements, such as optical instruments, photographic lenses, telescopes, etc.
