Plano-Convex (PCX) Lenses have a positive focal length, making them ideal for collecting and focusing light in imaging applications.Fused Silica is commonly used in applications from the Ultraviolet (UV) through the Near-Infrared (NIR) and its low index of refraction, low coefficient of thermal expansion, and low inclusion content make it ideal for laser applications and harsh environmental conditions.
Hangzhou Shalom EO use fused silica materials from Corning, which has a stable physical and optical properties, and every pieces of lenses are measured in the Zygo interference system to assure the surface accuracy and performance of these UV optics.
