It is a quite easy job to select green dot laser alignment to make dot measurement out of your hand reaching work distance. For instance, when you are only selecting a quite low power green laser module with output power of 5mW, green laser beam is clearly visible at about 2 kilometers work distance. Available with wide range output power from 5mW to 100mW, this laser diode module is just applicable for quite long distance dot laser alignment work fields. Unless the real dot aligning work distance is not exceeding 25 meters, this green laser dot aligning tool is just a very nice choice to do so.
When green laser beam is pointed under sunlight, whatever kind of output power made green dot laser alignment can be workable with clearly visible green laser dot projection on targeting surface. As a result, the real dot positioning work from green laser module should be just avoid direct dot positioning under sunlight, it will bring users super wonderful dot positioning accuracy under sunlight as well. According to exact working distance and lighting condition of working environment, users only need to select a correct output power made green laser alignment tool, it will make easy and quite accurate dot positioning result precisely and accurately.
The desired green laser dot diameter is always keeping the most compact size, thus green dot laser alignment has just got super wide applications in a lot of industrial and high tech dot measuring work fields. no matter what kind of targeting field and output power this green alignment laser dot is being pointed, users should always pay high attention to powerful green laser light and thermal energy emission, and take active measure of wearing proper laser safety glasses so as to achieve the most secured dot measuring result successfully.
