5mW green dot laser alignment is a very low powered dot projection tool. It is commonly being used for close distance dot projection in room operating occasions. If users want to make long distance dot measurement, higher powered alignment lasers are in need. In room working conditions, this low powered laser gadget can project super bright and visible green reference dot on flat surfaces. The light spot size can be as small as less 3mm. Usually this dot measurement tool is always being designed with adjust focus. According to different working distance, users can make free adjustment of the dot laser alignment until getting the most satisfied dot projection precisely and accurately.
In room dot projection working occasions, green laser alignment is always required to make long time continuous dot measurement. This always requires its inner green laser diode in the best working condition in work. In addition, this 5mW green dot laser alignment has also adopts internal metal heat sink cooling system. This kind of thermal stabilization control system always maintains its inner green laser diode and connected electric circuit board in stable performance. The metal heat sink will cool down the 532nm green laser diode from being burnt out during long time continuous dot projection. As a result, this alignment laser gadget is able to make long time continuous dot projection on required working surfaces freely and efficiently.
