Once users have got extremely strict requirement of dot projecting accuracy, users should pay special attention of exact working distance. In order to make sure of the best dot generation, the maximum dot alignment distance should be controlled within 20 meters. In addition, in front part of laser alignment tube, users can just make very simple screw of laser head, thus obtain quite satisfied dot generation according to free adjustment of laser dot size. Whatever kind of dot projecting condition, green alignment laser dot just keeps high beam concentricity, no change of green laser dot size with the moving, calibration or others.
The time 30mW green laser diode module is pointed on desired working surfaces, it is very important to make proper adjustment of laser dot projecting direction. In various advanced industrial precise machinery processing work, it is always able to make good performance. Before it is flown into the market, it just passes through super strict test. More than 5 hours beam stability test has just made this advanced alignment laser pointer obtain the most satisfied dot projection efficiently.
