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...

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...

The fused silica dome is a high performance optical protection element for scenarios where UV, high temperature, chemical corrosion, high power lasers, low thermal expansion and high transmittance are required. Yutai Optics recommends the use of fused silica JGS1. Read more...
