When dot alignment is processing at quite long work distance, although it is quite difficult to reach with simple manual dot projecting tool, it is always a quite convenient work to make use of a 50mW 635nm red dot laser module. It is a quite mature laser diode tech applying device. When it is trying to make continuous dot alignment onto multiple working surfaces, this red laser alignment is not only applying the best quality laser diode and qualified optic lens, but also getting constant power source from DC power supply. It is just workable with the most intense and powerful red laser light emission, and highly clear red reference dot projection at long work distance and other complex working environments etc. The genuine use of 50mW 635nm red dot laser module is applying for various working environments. It is selecting an external AC/DC adapter, after the operation within 100V to 240V operating voltage, it is just applying for different working occasions. After correct converting of 9V 1000mA DC power supply, high power red laser is workable with the best quality red laser light source emission, and highly clear red dot projection as long as 25 meters. For the most important of all, the special use of extending electric wires are not only allowing freely installed distance of 3 meters, but also assuring the most convenient and stable red reference dot projection under overheating and over current impact as well.Comparing with a simple red laser pointer, after special use of inner cooling system of metal heat sink cooling system, 50mW 635nm red dot laser module just gets even better performance and better laser beam stability in continuous use. It is employing the most durable aircraft used aluminum alloy housing tube. Under operation with super stable performance under mechanical moving or shocking, this dot laser alignment is also keeping good laser light cycling use and highly clear red dot indication for multiple application fields, including laser marking, laser engraving, military targeting, drilling system and other high tech work fields etc.Either 50mW 635nm red dot laser module is pointing for quite long work distance or quite long time, it gets the most important design of APC, ACC driving circuit board. The intelligent feedback system is just making perfect protection of alignment laser from overheating and over current, and reduced possibility of laser tube burning out or damage in continuous use. Within daily continuous red dot projection of 8 to 10 hours, after high attention to any thermal energy hurt to eyes and proper wearing of laser safety goggles, this high power red dot laser makes sure of free and secured measurement perfectly.
