• 【Lasers Focusing Lens】This product features a 20mm zinc selenide (ZnSe) lens specifically designed for lasers. It comes in three focal length options - 8mm, 63.5mm, and 101.6mm, suitable for power ranging from 50W to 100W.
• 【High Light Transmittance and Temperature Resistance】Made of PVD coded zinc material, this lens offers high light transmittance of up to 8%. It has low lasers transmission loss, low absorption, and can withstand high-power lasers without compromising performance.
• 【For Durable and Wipe-Resistant Coating】The enhanced double-sided coating process ensures a firm and long-lasting coating that is resistant to falling off and wiping. This results in a lens with a longer service life and better durability.
• 【Thin Spot and Fast Cutting Speed】With a polished cylindrical , this lens maximizes light transmission, reduces stray light, and improves its ability to handle reflections. As a result, it produces a finer spot size and enables fast cutting speeds.
• 【Wide Application and Complete Specifications】This lens is suitable for cutting machines and engraving machines from major brands. It offers complete lens specifications, compatibility with a wide range of equipment.
