CO2 Laser Lens 12mm 2.5 Inch ZnSe 63.5mm

12mm 2.5-inch ZnSe 63.5mm CO2 Laser Lens. This lens, made of ZnSe PVD material, guarantees excellent cutting parameters. If your old lens is cracked or scratched and the laser isn't working properly (not cutting plywood or components), it's time to replace the optics. The anti-reflective coating on both sides of the lens minimizes laser optics losses. It is resistant to the high temperatures generated during laser operation. Its lifespan is significantly longer and it exhibits increased resistance to higher operating temperatures than cheaper counterparts.
