Detail Information

Germanium Plano-Convex Lens for LWIR 8–15μm Infrared Systems


Product Overview

Felix Glass manufactures high-precision Germanium (Ge) plano-convex lenses designed for long-wave infrared (LWIR 8–15μm) and CO₂ laser optical systems.

These lenses are in-house polished and AR-coated to deliver stable infrared transmission, low optical distortion and reliable focusing performance in industrial, scientific and thermal imaging applications.

Germanium is one of the most widely used materials in infrared optics due to its excellent transmission in the LWIR range and strong performance in harsh environments.
