Engineered with double-sided coatings for durability and high-temperature resistance, it’s designed to maximize performance in 30W-100W CO2 laser engraving and cutting machines. ## Description Product description PARAMETERS Attentions Double-sided solid coating,Wiping resistant,Extended durability,Precision slicing polishing and grinding processes,High temperature laser resistance,Excellent optical properties,High working efficiency.Laser transmittance is as high as 99.5% Normally, Normally, the short focal length is suitable for engraving. If used for cutting, we suggest to work with long focal length. Causes of lens broken and tips (1) Ensure that the air cooling is good, otherwise the temperature will be too high and the lens will overheat and crack (2) There are condensation water drops in the lens barrel, which may cause the lens to break. (3)The lens is stuck or pollute with the jets of the cut or engrave material, Uneven heating for a long time is easy to cause broken. It should be cleaned with cotton ball dipped in absolute alcohol or acetone in time. (4) When adjusting the light path, the light path is not correct, the laser accidentally hit the edge of the lens and the junction of the lens barrel, resulting in broken. ABOUT LENS SHAPES Focal length is the distance between the lens and the workpiece(material being cut or engraved). Before replace or install the lens, please confirm the diameter and focal length firstly. It is recommended to use convex upward, flat or concave facing the engraving or cutting material.
