it is a quite nice job for users to make measurement with economy red dot laser alignment. When it is making use of 650nm red laser diode, owing to its quite long development history and quite mature laser diode tech, when it is made into a real dot alignment tool, this 650nm red laser module is just available with quite low price and also easily obtaining super stable and reliable red reference dot targeting in long term use. Owing to its easy adjustment of laser beam focus with front part laser beam aperture screw, red laser light is temporarily focused, and generating a quite compact size red reference dot in distance.
Within the selectable output power of 5mW to 100mW, economy red dot laser alignment is just getting super wide range work distance application. A low power 5mW red laser module is workable for formal inner room close distance and hand reaching work place. However, once users are getting the employment of this laser diode module with high power up 50mW to 100mW, red laser dot alignment is just workable at quite long distance. No matter what kind of working surface, noncontact red alignment laser dot is making no barrier dot measuring work, and then obtaining a no mistake dot targeting easily.
The operation of economy red dot laser alignment gets free use at quite long work distance. This is a formal TEM laser beam mode made laser dot measuring tool, when the real dot alignment distance is properly controlled within 25 meters, this red laser module can easily make an easy and accurate dot aligning instruction. In addition, under condition that users are paying special attention to powerful red laser light and avoid eye exposure at quite close distance, it is just a necessity for users to wear a pair of laser safety goggles until getting no danger alignment perfectly.
