Uxcell 18mm CO2 Laser Lens FL50.8mm Focus Focal Lens for 0-200W Laser Cutter

<div class="div-os-obd"></div><ol><li>The CO2 laser focus lens are crafted from premium zinc selenide, featuring a laser transmittance of up to 99.8%, a fine spot with minimal loss, low absorption and high light transmittance.</li><li>Utilizing an enhanced double-sided coating process, the coating is durable, non-flaking, scratch-resistant and heat-resistant, ensuring long-term use. Through meticulous cutting, polishing and coating, the engraver focal lens's light transmittance is effectively increased, stray light is reduced, and backlight glare resistance is enhanced.</li><li>Laser focal lens is designed for CO2 laser engraving and cutting machines ranging from 0W to 200W, which is widely used in industrial marking, precision cutting of non-metallic materials, artistic engraving, etc., effectively reducing laser losses and preventing adhesion of splashes or debris during cutting.</li><li>Note: For minor particles, use an air bag to blow away loose particles from the optical surface, or gently wipe the lens surface with a damp cotton ball to avoid friction.</li></ol><div class="div-os-obd"></div>
