Features: Newly Upgraded Ultra-fine  Laser: the laser adopts 4-fold lens group collimation and focus technology, the optical power is 4.5~5W, the laser focus area is reduced to 0.02mm², the high-density laser can easily cut 10mm thick wood boards and 6-8mm black acrylic ; Can directly engrave mirror stainless steel metal and ceramics. Upgraded Version of High-performance Fixed-focus Laser: Engraving can be done without adjusting the focal length; the newly upgraded compressed spot increases the energy concentration by 200%, and the spot size is only 0.02mm², which can take into account both precision engraving and high-energy cutting. At the same time, the laser power of fixed-focus laser is more stable than that of zoom laser. Easy Installation: The all-aluminum alloy anodized structure design makes the machine more durable and improves the accuracy of engraving. The portable all-metal structure, 85% pre-assembly, can be installed in 5 minutes. Eye-protection Flame-retardant Filter Panoramic Glass: The flame-retardant filter panoramic glass can filter 97% of the ultraviolet light, which plays a very good role in protecting your eyes. You and the people around you do not need to wear goggles, you can also clearly Watch laser engraving. Reduce the cost of your goggles and the inconvenience of wearing goggles. The glass is flame retardant and safer to use. More Humanized & Safe Design: ith knob for easier to adjust the height of the laser and a horizontal gyroscope auto stop working when it is tilted. Wide Compatibility: The machine can be compatible with various mature engraving software, such as LaserGRBL, LightBurn, support Win XP / Win 7 / Win 8 / XP / Win 10, and also support MAc system (LightBurn), engraving file format supports NC, BMP, JPG, PNG, DXF etc. Specifications: Model: ATOMSTACK P7 M40 Frame Material: Aluminum alloy Input Voltage: AC100-240V, 50/60Hz Output Voltage: DC12V, 5A Engraving Size: Recommend Print Size 200*200mm Engraving Materials: wood, bamboo, cardboard, plastic, leather, MDF, slate, lacquered metal, mirror stainless steel; Cutting Material: cardboard, non-woven fabric, veneer, acrylic, some thin plastic board, sponge, MDF, leather; Spot Size: 0.02& 13217; Laser Power: 40W Laser Output power: 4.5-5.5W Wave Length: 445 ± 5nm Engraving Accuracy: 0.01mm Focusing Method: fixed focus laser, no need to focus Laser Protective Cover: Protect the user's eyes and prevent pets from grabbing the laser spot.
