NEJE A40640 Ⅱ Laser Module Description & Details


A40640 (The most widely used module) is a classic creative master dual beam zoom laser module, it is the world’s first 2 beam laser diode engraving and cutting module with zoom design, with the best metal engraving ability, fast groove engraving ability, thick material cutting compatibility, Make it the most widely used module. Due to the built-in NEJE unique fiber compression technology, It has a very strong energy density (0.04×0.06mm with 12W+ pulse and 11W continuous optical power),  There are very special and top artistic expressions on the carvings of stainless steel grayscale carvings, stone carvings, Glass Carving, hardwood reliefs, canvas art, and other materials.  The A40640 is the only high-power module with variable focus section, The optimized A40640 II has higher cutting reliability, The short focus is suitable for carving hard materials such as metal stone and cutting materials with high density such as mdf, The long focus has better depth of field and smaller included angle for cutting thick wood and other materials. The excellent design makes the A40640 have a very strong vitality from the first creator of high-power diode laser to today, Due to the high power density, it has an equivalent application higher than 20W (optical power) laser in large area image engraving, If you only consider 1 module to help you solve all the needs, it is the best choice.

  1. How much would it be to upgrade my NEJE Master 2 using this module and kit? I have owned my NEJE Master 2 since around 2018 and it is still going strong, with one or 2 strengthening ‘tweaks’ to improve longevity long beyond manufacturers warranty.
    Where is it available to buy?
    Assuming that it would be possible
