Focus Lens for Zinc Selenide Machine Engraving and Cutting Machines - Wavelength 10.6um(D20/F25.4mm)

Premium zinc selenide material ensures exceptional durability and performance, specially designed for applications on high power machines. Achieves transmittance of more than 99% at a wavelength of 10.6um, thanks to advanced anti-reflective coatings that minimize scattered light and improve machine efficiency. Precision engineered with a focal length tolerance of ±1% and a profile tolerance of +0.0/-0.1mm, ensures optimal sharpness during operation. Double sided anti-reflective film plating and cylindrical polishing provide superior light transmission and reduce the risk of lens damage due to overheating or . Simple installation with clear guidelines for optimal positioning; regular maintenance with anhydrous alcohol keeps the lens clean and working at peak performance.
