Whenever users are trying to make dot alignment at a bit longer work distance, it is just the good chance for users to make good use of Berlinlasers blue laser diode module. It is a very easy operated dot alignment tool, when it is getting higher operating voltage 4.2V DC input power supply connect, it keeps constant blue laser dot targeting immediately. Owing to its high power 445nm blue laser diode employment, this blue laser module gets the best use of APC driving circuit and metal heat sink cooling system, making sure of the most reliable blue laser dot targeting all the time.
This blue laser diode module uses qualified glass coated lens as its laser beam emitting source, blue laser beam and blue laser dot targeting keep no light decay in long term use. Users should only select correct output power and make proper adjustment of laser beam focus, this laser dot alignment tool gets easy and quick laser dot alignment precisely and quickly.
