It is an easy job to make dot measurement with a green laser diode module. It is using DC input power supply as its power source, while green laser dot is keeping continuous alignment and projecting in desired working surfaces. In practical dot measuring work, green laser module gets a wide range output power from 5mw to 100mw, which is able to project highly bright and visible green laser dot at different work distance after the selection of correct output power.
In order to get bright enough dot laser alignment result, green laser diode module is getting correct operating voltage of 3v or 4.2v DC input power supply. Formally slower power green laser alignment with low power of 30mw is using 3v DC power, while high power green laser module should only be equipped with higher operating voltage of 4.2v so as to keep high brightness green alignment laser dot positioning as expected.
According to very simple adjustment of laser beam focus of the laser beam aperture part, green laser diode module is generating different size of green laser dot on targeting surfaces. This special part is just an important configuration for this dot laser alignment tool so as to always making sure if the most precise dot positioning. In addition, although green laser module only gets no more than 1 mrad laser beam divert, however, in order to avoid laser beam becoming decay or blue in distance, it is just a key point for laser diode module users to make perfect control of work distance within 25 meters. When users are paying enough attention to powerful green laser light during the continuous laser dot alignment work, users should never forget to wear laser safety glasses until getting the most satisfied dot alignment successfully.
