How to make good job with glass lens 650nm red laser diode module?

On consideration of high work efficiency and high precise dot alignment at various work distances, on consideration of low production cost and long lasting work, it makes good job with a direct diode emission made device of a 650nm red laser diode module. It emits highly visible and intense red laser beam from an inner red laser diode. Being made with different dimension and high duration metal housing tube, together with electric wires extension, it enables freely installed distance of 3 meters, easy and quick reaching of red dot alignment onto any raw material surface constantly.
The whole process of laser dot alignment work with a laser diode module should be maintaining its stable performance as expected. It applies a qualified glass coated lens and glass window, under operation of moisture or dust, it still gets perfect protection of itself and maintains highly clear and accurate red dot alignment at various work distances. When it makes proper installation, without any limitation by long distance, high height or complex working environment etc, it brings users the best dot alignment solution for all machinery processing works perfectly.
Applications: industrial precise dot alignment, drilling system, laser marking, laser engraving, military targeting and high-tech
