Focusing Lens for Machines Engraving and Cutting in Zinc Selenide - Wavelength 10.6 um(D12/F50.8mm)

Made of high quality PVD zinc selenide materials, this lens ensures a smaller focusing point and can bear higher powers, improving the engraving and cutting efficiency of the machine. Equipped with an anti-glare film, this lens boasts a transmittance of more than 99% at a wavelength of 10.6 µm, ensuring optimal performance for your machine applications. Double-sided anti-reflective coating and cylindrical polishing significantly increase the transmittance of machine components, while effectively reducing stray light for precise results. Designed with strict tolerances: ±1% focal length tolerance, ±0.1mm thickness tolerance and +0.0/-0.1mm profile tolerance, ensuring superior accuracy in your projects. Easy installation with clear guidelines to ensure that the convex side is mounted upwards; includes maintenance tips to avoid overheating and ensure the longevity of the lens.
