If users are not able to make precise enough dot measurement at different work distances, it should be an easy job to operate a Berlinlasers 532nm green dot laser module within 5mW to 100mW. It projects the most visible and the most sensitive color green laser light from a middle wavelength of 532nm green DPSS laser system. After getting less than 1mrad laser beam divergence and special tem00 laser beam mode, it is working well with the brightest dot alignment at various work distances.
On basis of the use of 16mm and 26mm diameter metal housing tube, cooperating with extending electric wires for both 532nm green laser alignment and DC power supply, it enables the maximum installed distance of 3 meters, easy reaching and good direction green dot emission in distance. Every time it gets correct output power and freely adjusted laser beam focus, it assures concentrated green laser light and high precision dot alignment for industrial precise device manufacturing works, drilling system, laser marking, laser engraving and high tech work etc.
