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 sur... Read more...

Fresnel Lens is a specially designed optical lens that focuses or diverts light by breaking down the curved surface of a conventional lens into a series of small concentric rings of prisms. Read more...

Sapphire Windows are glass with parallel surfaces used to enable optical radiation to pass from one environment to another without allowing environments to mix. Material, transmission, scattering, wavefront distortion,damage threshold and resistance to certain environments should be considered when selecting windows.
