520nm green laser diode gets much shorter development history than 532nm green DPSS laser, however, owing to its direct diode forest green laser beam emission, it is always much more workable for long-term continuous dot alignment work. In front part of green laser module, it is also designed with focusable beam. According to very simple screw of head part, it can get different size green reference dot on all desired working surfaces. As a result, in various kinds of industrial dot alignment work, this advanced green laser dot measuring tool always keeps its high beam concentricity, thus always ensuring the most precise and accurate dot positioning result on all working surfaces efficiently.
At the same time, according to the special adoption of larger size laser tube diameter of 26mm, there is always enough space reserved as its metal heat sink cooling system. In the tail part of laser tube, it is just filled with silicon gum. It cannot only help laser diode module to get efficient thermal emitting, but also make sure of good connection with electric line outside the laser alignment. In addition, this dot laser diode module also selects higher operating voltage of 8.4V. Only if users are making proper operating voltage DC power supply, it can just project bright and visible enough green laser dot on all desired working surfaces.
In order to make dot laser alignment workable in all kinds of working environment, even harsh working fields, 520nm green laser diode module adopts aircraft used anodized aluminum as its housing material. In 24 hours continuous dot positioning work, it can make sure of the most efficient thermal conductivity. For the most important of all, in quite harsh working environments, the high duration laser tube can make sure of perfect protection from shaking, calibration, and anti-static. According to proper adjustment of alignment laser dot targeting direction, this advanced laser diode module can always make sure of high brightness green dot positioning on all desired working surfaces efficiently.
