In special use of highly clear dot measurement at quite long work distance, it is not a hard work after correct choice of 50mW pro red dot laser alignment. It is an industrial stabilized laser device. When it makes good use of inner metal heat sink cooling system and import 635nm red laser diode inside durable metal housing tube, this red laser module is generating low divergence red laser beam and the most compact size red dot projection at long work distance.
This pro red dot laser alignment adopts 26mm diameter aluminum alloy housing tube. After quite easy connects with a DC power supply and easy installation, it makes highly clear and quick red dot projection for all precise device manufacturing work fields.
