## 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.

Review: Great lens - I've been buying inexpensive lenses for my CO2 laser on desertcart for a couple of years now and have never had a problem with them. I've tried lenses that cost twice as much and saw absolutely no difference in performance. I consider lenses to be a consumable and thus the less expensive the better and these work well.
Review: Very Surprised on how well this performed. - This lens is fantastic. I've been using much more expensive lenses in my laser cutter but no more. This lens out cuts and out engraves the pricier ones. Honestly, when I first got it I wasn't too impressed. Although it was very well packaged, the lens appeared to be a little cloudy and I really didn't expect much out of it. However, once I got it in my machine it performed better than I ever would have imagined. I won't be going back to my old lenses.
