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...

An infrared cut-off filter (IR Cut Filter) is an optical element that is mainly used to block infrared light (wavelength usually greater than 700nm) and allow visible light (about 400-700nm) to pass through. It is widely used in modern imaging systems, especially in digital cameras, smartphone cameras, security surveillance and other areas of critical importance. Read more...
