High quality 18mm ZnSe focus lens for as high as 180Watt without cooling needed
Better quality means 15~20% more power than the others!
Type: Positive Meniscus Focus Lens (imported)
Laser type: 10600nm CO2 Cutting: Very good 6mm acrylic, 20mm wood
If you cut thick materials or have a laser like a K40 which doesn't have a mechanized bed or adjustable head - this is the lens for you. Physics - the longer the focal-length of the lens, the more less accurate you have to be in Z. With this lens I can cut anything from paper to 1/4" with kerf < 0.2mm without adjusting the focus plane. This is your easy button for your focus woes. Hit it.3/23/2017
