on the basis of an ac/dc adapter, not spending extra time on alkaline battery change, the usual use of a 650nm red dot laser module is working for a quite long time. the inner part of an import 650nm red laser diode is cooperating with a metal heat sink cooling system. as a result, it is not only working well with increasing laser beam stability of at least 40%, but also getting high level of laser beam stability under constant work time of 10 hours per day.
when 650nm red dot laser module gets unique use of a qualified glass coated lens and glass window, together with strict laser beam stability test and aging preventing test up to 24 hours, it is always working well with high transmittance red laser light source emission. for the most important of all, in those of harsh working occasion of moisture, dust, rain, water or fog, this 650nm red laser alignment still gets perfect protection of itself and maintains stable dot indication for a lot of application fields, including laser marking, laser engraving, drilling system, red laser sight, military dot positioning and high tech work etc.
designed with highly durable anodized aluminum alloy housing tube, together with electric wires extension for both of 650nm red dot laser module and dc power supply, it is applying for majority regions and countries, and making no barrier and no mistake dot alignment for all precise machinery processing works. whenever it makes proper adjustment of both of laser beam focus and dot emitting direction,this alignment laser gets the most efficient conversion of ultra compact size and bright dot alignment in continuous use. any time users are taking active laser safety measure and wearing proper laser safety goggles, it brings users no danger and no mistake use in all working occasions effectively.
