Aspherical Lenses

Aspherical Lenses

The Aspherical Lens is mainly used to focus light, and it corrects Spherical Aberration. Aspherical Lens increases the numerical aperture of the lens while minimizing system aberrations. Aspherical Lens also reduces the number of Optical components required in an Optical System.
