in order to make ultra clear and precise dot projection at long work distance, it might be far more enough than formal hand reaching, it would be a much better job to use a highly intense beam emitting tool of a 650nm red laser diode module. it is always in need to make long lasting and high stability red laser beam and red dot projection from laser beam aperture. after its special use of thermal emitting system inside a high duration metal housing tube, it achieves long lasting red dot projection within 10 hours per day.
according to real work distance and lighting occasion, this laser diode module enables correct use of output power of 5mw to 100mw. it makes ultra clear red dot projection within great distance of 25 meters, and brings users no mistake dot alignment for all labs, institutes and colleges etc.
applications: industrial precise device manufacturing, drilling system, laser marking, laser engraving, high tech and lab experiment etc
