While users are selecting high powered dot alignment laser, users might have noticed that there is totally no worrying about its stability and reliability. During its design, it has paid special attention to its inner design, especially large space for thermal stabilization control system. Since large laser power and energy might produced from high power laser alignment during long time continuous dot projection, thus thermal control system is especially important part to ensure its stability in real operation. In order to make high power laser alignment project stable and reliable dot projection on required working surfaces, it has been specially designed with metal heat sink thermal control system. This kind of precise design has just ensures wonderful control of its inner electric circuit board and laser diode in the best working condition no matter how long it has lasted in continuous dot projection.
