Product Overview
Optimized for Industrial CO2 Systems
Specifically engineered for industrial CO2 laser processing. These ZnSe meniscus lenses provide a smaller focal spot and higher energy density, making them ideal for high-speed laser engraving, precision thin-metal cutting, and non-metal marking systems.
Precision Optical Fabrication
Clarvis Industrial offers a full range of diameters (Ø12mm to Ø38.1mm) and focal lengths (FL 1.5" to 7.5"). We provide custom AR coating options to minimize absorption and prevent thermal runaway, ensuring stable performance even in high-power 150W+ CO2 systems.
Rigorous Quality & Compliance
Every ZnSe lens undergoes strict interferometric testing and spectrophotometer validation. We guarantee material uniformity and surface accuracy. Clarvis Industrial adheres to global export standards, providing reliable, unrestricted supply of non-controlled optical components.
