When dot alignment work is processed at quite long work distance, formal manual dot projecting tool cannot be comparable with advanced laser tech applied blue dot laser module. The employing of import 445nm blue laser diode gets beginning high power up to 50mW to 100mW, being made with inner metal heat sink cooling system inside aluminum alloy housing tube, this dot laser alignment is a real industrial stabilized laser device. After easy connect with DC input power supply, it produces continuous and highly clear blue reference dot projection in distance easily.
Blue dot laser module emits quite powerful blue laser light and thermal energy from beam aperture. The special design part of APC, ACC is preventing increasing temperature and serious electric current impacting, achieving highly stable blue reference dot projection within 8 to 10 hours per day. When this dot laser alignment tool is properly installed and adjusted, within the maximum distance of 3 meters, it achieves the most satisfied dot positioning result for laser show, laser displaying, military targeting and laser medical therapy works etc.
