Any time users are trying to make highly clear dot alignment at quite longer distance than formal hand reaching, it is not easy to reach with any manual dot projecting tool or a simple blue laser pointer, it makes even more efficient job with a blue laser diode module. It keeps work with intense blue laser light emission directly from a 445nm blue laser diode within 50mW to 100mW. Any time it makes advanced use of qualified glass coated lens, metal heat sink cooling system inside 16mm diameter metal housing tube, this blue dot laser just assures high quality blue laser light emission, highly clear and highly stable blue dot alignment for laser show, laser displaying, laser communication, high tech and lab experiment work etc.445nm Blue Laser Diode Module
