I want to share my experience of using green dot laser alignment to make dot positioning work for my laser marking work. This dot alignment tool is very simple and easy to operate. It is just a 16mm diameter laser diode module, while according to very simple connection with 3V DC input power supply, it just begins to project super bright and visible green laser dot on desired working surfaces efficiently.This laser alignment always allows about as long as 3 meters free adjustment and installation. It can be mounted on any required working surfaces, no matter vertical or horizontal surfaces. The laser dot projection is very rapid and accurate.
