(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. Parameters Tips 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. Usually one co2 laser engraver needs 1 pcs focus lens and 3 pcs reflective mirrors. Lens shape: 50.8mm/2 " and 63.5mm/2.5" FL are plano convex or meniscus; 127mm/5 " FL is meniscus; other FL (38.1/1.5", 76.2mm/3 ", 101.6mm/4") is plano convex. The above is the default shape. If you have special needs, we can customize it. Please send us message. Test Process Review: Good fit works fine - installed in 70W Boss Laser LS1420. No issues Review: Flir E4 Macro Lens - - Used the 20mm 4" on my Flir E4 (upgraded E8 hack) for Micro Electronic repair. - Made a huge difference in close up resolution! - The 3D printed bracket covers up the MSX camera image. So all you get is thermal only. But image is clear enough to not need MSX overlay (I think. Time will tell). - If I had to do again. I would order a larger diameter, to get rid of the circle effect in the image. See photos. But it's really not that bad, with the 20mm. - In short.
