450nm 6W 12V Laser Module with Ultimate Focus for Metal Engraving and wood Carving - NEJE E30130- Need air assistance to protect the lens

Description NEJE E30130 is a cutting module specially designed for high-precision and stable cutting. It adopts single beam optical compression technology to make X and Y have stable square characteristics in each focal length. 0.06x0.06mm focus and 20mm (lens to focus) fixed focal length, built-in high-pressure air auxiliary interface , can directly connect 4mm high-pressure pure air pump, 300mm/s directly and cleanly cut 3mm plywood, easy to focus, can adjust the focus through fixed thickness, it is a better choice for users who use the cutting function a lot, and for users with higher XY direction symmetry and cutting accuracy. Printing a 3D nozzle protection lens for engraving is also a good choice, E30130 can also directly engrave stainless steel, stone, hardwood and other materials. Of course, the cutting process that requires extremely high symmetry is the biggest feature of E30130. SPECIFICATION Module: NEJE E30130 Focus: 0.06x0.06mm Focus method: fixed ( about 10mm from the
