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...

Avantier designs and manufactures custom UV lenses designed for wavelengths below 400 nm, ideal for UV laser focusing, collimation, imaging, and other precision optical applications.
