What are aspheric lenses?
An aspheric lens is an optical lens whose surface is not spherical but has a more complex curved shape. Compared to conventional spherical lenses, aspheric lenses are designed to better correct aberrations in an optical system, thereby improving image quality.

What are the characteristics of aspheric lenses?
Aspheric surface: its surface curvature varies with position and is usually described by a high order polynomial or conic curve.
Aberration correction: it can effectively reduce spherical aberration, coma aberration, astigmatism and other aberrations to enhance imaging clarity.
Design flexibility: optimize optical performance by adjusting the shape of the surface to meet specific needs.
