What is a ZnSe Focusing Lens?
A ZnSe (Zinc Selenide) focusing lens is a high performance infrared optical component designed for CO2 laser systems. It is widely used to focus or converge laser beams at 10.6μm wavelength, enabling precise energy delivery for cutting, engraving, welding, and marking applications.
Why Use ZnSe for CO2 Laser Optics?
ZnSe is one of the most commonly used materials in infrared laser optics due to its high transmission at 10.6μm, low absorption, and excellent resistance to thermal shock. These properties make it ideal for high power laser environments.
