Aspherical Lens

An aspherical lens is a lens whose surface profiles are not portions of a sphere. Unlike traditional spherical lenses, which have a constant curvature across the entire surface, aspherical lenses feature varying curvature. This design helps to reduce optical aberrations, particularly spherical aberration, which can occur when light rays passing through the edges of a spherical lens focus at different points than those passing through the center.

Key Features

Non-spherical shape: The curvature of an aspherical lens changes gradually from the center to the edge, allowing for more precise control over the path of light rays.
Spherical aberration: Aspherical lenses minimize this by focusing light more accurately, leading to sharper images.
Coma and astigmatism: These lenses can also reduce other aberrations like coma and astigmatism, especially in wider field-of-view applications.
Thinner and lighter: Because they correct for aberrations more effectively, aspherical lenses can often be made thinner and lighter than spherical lenses with the same optical power, making them more comfortable in applications like eyeglasses.
