Zinc Selenide Machine Focusing Lens for Engraving and Cutting Machines - 10.6 µm Wavelength (D19/F38.1mm)

High-quality zinc selenide material ensures exceptional durability and performance and has been specially developed for high-performance machine applications. Achieves over 99% transmittance at a wavelength of 10.6µm thanks to advanced anti-reflection coatings that minimize stray light and increase machine efficiency. Precision machined with a focal length tolerance of ±1% and a profile tolerance of +0.0/-0.1mm to ensure optimal clarity during operation. The double-sided anti-reflective film coating and the cylindrical polishing ensure excellent light transmission and reduce the risk of lens damage caused by overheating or . Easy installation with clear guidelines for optimal positioning; regular maintenance with anhydrous alcohol ensures that the lens remains clean and functional.
