BICC-UV: Laser Grade Biconcave Lenses, Fused Silica
BICC-UV: Laser Grade Biconcave Lenses, Fused Silica
Laser quality diverging and expanding lens for UV, high energy laser and performance-critical applications; 193nm to 1550nm. Ideal for high performance and high power light expansion tasks in the UV through near-infrared, these equi-concave lenses are made from UV-grade fused silica and designed to meet the most stringent requirements of laser applications. They are offered with a large selection of optional high energy AR coatings.
