Besides very common 532nm green laser, 520nm green laser diode module is also a quite wonderful choice to get high brightness and high visibility green laser dot source for industrial dot alignment work. On basis of its direct laser beam emission from 520nm green laser diode, it just gets high stability and high reliability laser dot in color of forest green. It is much more workable for long-term continuous dot positioning work.Not the same as common dot laser, this 520nm green laser diode module always selects even higher operating voltage of 8.4V. It selects even higher operating voltage than common laser. In order to get high quality green dot projection, this dot laser selects the copper equipped 520nm green laser diode as its core part. In continuous dot alignment work, it can make high speed temperature cooing down, thus always enables good performance in all kinds of industrial dot projections.Technical data:Item: Berlinlasers Green Laser Diode ModuleOutput power: 20mW-30mWLaser safety class: IIIa
