For a 50mW 520nm module, this price is almost our production cost. The green line is uniform and bright; the collimation and stability are very high. The laser's dot/line is adjustable so that you can change the size of the laser spot and the thickness of the laser line. Even under the sun, the laser light is visible. We adopt the diode imported from Germany, which has high stability and can work 24 hours a day. The housing material of this green laser module is corrosion and high-temperature resistance, effectively extending the useful life.
