D25 ZnSe Focus Lens

Jh znse lens  are the high quality spare parts of co2 laser engraving machine, laser cutting machine, laser marking machine and laser carving machine.  jh znse lenses are available with a broadband ar coating optimized for the 7 - 12 μm spectral range deposited on both surfaces. This coating greatly reduces the high surface reflectance of the substrate, yielding an average transmission in excess of 97% over the entire ar coating range.in the process of co2 laser cutting, drilling, carving& other laser system. Our products canwithstand high power density; and the film is solid, with which the lens areresistant to wipe. Because of the double-side film, the filterability of thelight (the wavelength is 10.6μm) can reach 99%.             general requirements for lens fabrication material: cvdznse(usa)    wavelength: 10.6μm focal length tolerance: ±1% form tolerance: +0.0/-0.1mm thickness tolerance: ±0.1mm type: λ/2 632.8nm finish: 20-10 eccentric:
