Application:For Raytools BM115 Laser Cutting Head Focal Length:100mm/150mm/200mm If the lens is damaged or contaminated, it may lead to a decrease in laser cutting efficiency or a bad cutting effect. This anatomically correct human foot model uses 2.85mm filament to attach and hold the bones together. The filament allows for some movement between bones The focusing lens plays a crucial role in converging the laser beam to a specific focal point. It enables precise and controlled laser cutting, engraving, or... Startnow Laser Focusing Collimating Lens With Lens Holder For Raytools BT240S BM111 Therefore, it is necessary to pay special attention to the cleaning and maintenance of lenses during use. Collimator lens: used to recombine the scattered laser beam into a parallel beam after the laser beam is transmitted through optical fiber. Focusing lens: focuses the collimated parallel light beam on a very small point, thus producing high-density energy points when cutting materials. 2pcs/set:1st Convex-Convex, 2nd Concave-convex Lente De Proyector Raytools BM115 Focus Lens Collimator Lens With Holder D37 F100 F150 F200mm For Raytools BM115 Laser Cutting Head Lens 50 Mm Lens
