Comparing with a simple red laser pointer only used for temporary dot positioning works, it makes good job with a 650nm red laser diode module for both long distance and long lasting use. It is applying an import 650nm red laser diode within 5mW to 100mW as beam emitting source.
In various industrial precise dot measuring work fields, after correct use of output power and freely adjusted laser beam focus, this red laser diode module assures highly clear and increasing brightness red dot alignment in distance. In addition, not relying on any manual labor force input, within freely installed distance of 3 meters, red dot laser assures no mistake and noncontact use for drilling system, laser marking, laser engraving, red laser sight, laser medical therapy and high tech etc.
