After constant technical innovation of 635nm red laser diode tech and qualified glass coated lens with different fan angles, it is being made into a quite practically used device of 635nm red line laser module. It generates the purest red laser light directly from 635nm red laser diode. When it gets the lowest laser beam divergence of less than 1mrad and special TEM00 laser beam mode, it is getting super fine and bright red line, also keeping highly straight red line indication at great distance and long distance in constant use. Employing the most qualified glass coated lens within 10 degree to 110 degree, not affecting by any harsh working occasion of moisture or dust, red line laser module is projecting highly straight red line within 0.5 meter to 6 meters. It should be operating with basic measurement of line length, line fineness and work distance, thus getting correct choice of optic lens degree. After its proper installation and adjustment of laser beam focus, red laser line generator makes the most precise line positioning results perfectly.
