Product Overview
CVD ZnSe Plano-Convex Lens 5mm Diameter 400mm Focal Length for CO2 Laser and LWIR Applications
The CVD ZnSe Plano-Convex Lens from iroptical is designed for infrared focusing and beam control applications requiring high transmission, low scattering loss, and reliable thermal performance. Manufactured from chemical vapor deposited zinc selenide (CVD ZnSe), this lens provides excellent optical performance across MWIR and LWIR wavelengths, making it suitable for CO2 laser systems and infrared optical assemblies.
With a 5mm diameter and 400mm nominal focal length, this precision infrared lens offers stable performance at 10.6um while maintaining useful transmission characteristics from visible alignment wavelengths to long-wave infrared applications.

Material Advantages of CVD ZnSe
CVD ZnSe is widely used in infrared optical applications because of its broad transmission range, high optical transmission efficiency, low scattering loss, and excellent thermal stability. These properties make it particularly suitable for high-power CO2 laser environments and demanding infrared optical designs.
For custom optical designs, engineers can also evaluate CVD ZnSe Blanks for application-specific lens manufacturing and precision infrared component development.
