Product Family Description

Negative Focal Lengths for Beam Expansion or Light Projection Applications
Wavelength Range of 200 - 2200nm
Popular UV-AR Coating Option Available

These high performance UV optic elements are manufactured utilizing state of the art CNC equipment. Zygo’s GPI-XP Interferometer is used to assure the surface accuracy and performance of these UV optics. UV Grade lenses are precision manufactured using research-grade synthetic fused silica. In addition to providing excellent transmission characteristics and higher operating temperatures, synthetic fused silica lenses also exhibit an exceptional inclusion specification and chemical purity. These lenses make a superior choice for many laser and imaging applications, particularly those involving ultraviolet wavelengths. A broadband anti-reflection coating is avaliable for optimized throughput in the ultraviolet spectrum.
