Zinc Selenide machine Focusing Lens for Engraving and Cutting Machines - 10.6um Wavelength(D20/F101.6mm)

Premium zinc selenide material ensures exceptional durability and performance, devised specifically for high-power machine applications. Achieves over 99% transmittance at 10.6um wavelength, thanks to advanced anti-reflection coatings that minimize stray light and enhance machine efficiency. Precision-engineered with a focal length tolerance of ±1% and profile tolerance of +0.0/-0.1mm, ensuring optimal and clarity during operation. Double-sided anti-reflection film plating and cylindrical polishing provide superior light transmission and reduce the risk of lens damage from overheating or . Easy installation with clear guidelines for optimal positioning; regular maintenance with anhydrous alcohol keeps the lens clean and functioning at peak performance.
