Any time users are trying to make highly clear dot indication at various work distances, it is not easy to reach with a simple laser pointer or any other manual dot projecting tool. However, only after easy use of an external AC/DC adapter, without spending extra time on alkaline battery power source, this blue laser diode module is working well with constant blue laser beam and blue reference dot projection from laser beam aperture. Every time compact size tube made blue laser makes proper installation and adjustment to correct position, it just makes sure of the lowest price and the most stable blue reference dot projection at various work distances.

From the very beginning design of 445nm blue laser diode module, different from a simple alkaline battery power source, it is making sure of constant blue laser light and blue reference dot projection from laser beam aperture. It gets no need to make battery change. On contrary, after easy use of an external AC/DC adapter, it always makes easy and constant blue laser beam and blue dot emission from laser beam aperture. It is applying an import 445nm blue laser diode within 50mW to 100mW. After getting at least 40% improvement of laser beam stability, and making constant blue dot emission within long lasting time of 8 to 10 hours, this blue dot laser just keeps work with good laser light cycling use and highly reliable blue dot emission onto various working surfaces.

Either dot projecting work is processing for long distance or long time, this 50mW 445nm blue laser diode module makes the best use of a qualified glass coated lens. It is keeping work with high transmittance blue laser light, and highly clear blue dot alignment at long work distance. It is getting special use of a glass window in front of laser beam aperture, every time it is pointing under harsh occasion of moisture or dust, this dot laser alignment still gets perfect protection of itself, and making sure of charming blue laser light emission and highly clear dot projection for laser show, laser displaying, decoration, military targeting, laser communication etc.

Whatever kind of working surface it is pointing, with the assistance of a laser alignment mounting bracket and extending electric wires for both 445nm blue laser diode module and DC power supply, it enables freely installed distance of 3 meters, and the most convenient blue dot projection onto any various working surfaces. For the most important of all, after high attention to powerful blue laser radiation and reflection, and correct wearing of 445nm wavelength preventing laser safety goggles, without eye exposure to beam aperture, this high power blue alignment laser always makes easy and high security dot generation in distance perfectly.
