3 element long focal lens diode laser lens evaporator3 element long focal lens with high focal depth. An efficient lens for engraving and cutting. It has a high focal depth allowing to remain in focus. Focal tolerance + 10 mm. An efficient lens for 405 445 nm diode lasers. It has the best focal depth which allows cutting thick materials including wood, plywood, and foam. Optimal parameters: Focal range 49. 4 mm (2) Focal beam spot ~ 0. 156 0. 046 mm Optical transmission for 445 nm wavelength = 82% Using
