Zinc Selenide Focusing Lens for Engraving and Cutting Machines - 10.6µm Wavelength(D16/F101.6mm)

Made from premium PVD zinc selenide materials, this lens ensures a smaller focal point and can withstand higher power, improving the engraving and cutting efficiency of your machine. Featuring an anti-reflective film, this lens has a transmittance greater than 99% at a wavelength of 10.6µm, ensuring optimal performance for your machine applications. Double-sided anti-reflective coating and cylindrical polishing greatly increase the transmittance of machine components while effectively reducing stray light for accurate results. Designed with strict tolerances: ±1% focal length tolerance, ±0.1mm thickness tolerance and +0.0/-0.1mm profile tolerance, ensuring superior precision in your projects. Easy installation with clear instructions to ensure that the convex side is mounted upwards; includes care instructions to prevent overheating and ensure the longevity of the lens.
