It has almost double the output power of the 30W variant, which makes it more suitable for working on comparatively thin workpieces.
This combined laser beam results in high output power. The 40W module has two laser diodes arranged at a 90⁰ angle, whose beams are merged using a special prism lens. They all operate at a wavelength of 450nm. Three options available at the time of purchase are 7W (N25410), 30W (A40630), and 40W (A40640) laser modules. So, if you want, you can even upgrade the laser module later on. NEJE Master 2S Plus provides three options for laser modules, but it can also hold most of the laser modules NEJE currently sells.
