Under operation with continuous dot projection on multiple raw material surface, none of manual or mechanical dot alignment tool is not workable at all. However, under the operation of Pro red dot laser alignment and easy connect with constant electric power source from DC input power supply, it is keeping work with continuous red dot projection from beam aperture easily. According to quite easy adjustment of laser beam focus and dot targeting direction, this 635nm red laser module makes sure of easy and immediate dot projection on any vertical or horizontal surface easily. This pro red dot laser alignment generates high purity red laser light from 635nm red laser diode. It is emitting at least 3 times brighter light from formal 650nm red laser device. On basis of quite low beam divergence and good round shape red dot projection, a correct output power made red laser module ensures the highest level of accuracy dot generation within the maximum work distance of 25 meters. This industrial red dot laser ensures high level of accuracy dot projection for laser marking, laser engraving, military targeting, and drilling system etc. http://www.berlinlasers.com/pro-red-dot-projecting-laser-alignment
