Have you ever tried to make clear and accurate dot alignment? Either it is pointing at close or long distance, and other hard reaching places, it makes good job with a high brightness Berlinlasers 532nm green laser diode module within 5mW to 100mW. Not the same as a simple green laser pointer used for temporary dot positioning work, after advanced use of cooling system and APC, ACC driving circuit board, this green dot laser keeps work with the most stable and reliable green dot projection in long lasting use.
Being made with extending electric wires, this 532nm green laser diode module allows freely installed distance of 3 meters, easy reaching of green dot emission in distance. It gets no effect by increasing temperature and serious electric current impact. When green dot laser is mounting onto industrial device, it assures no mistake and no barrier dot alignment for laser marking, laser engraving, military targeting, laser medical therapy, scientific experiment and high tech work etc.
