Either dot aligning work is processing at close or long distance, without the use of sunlight, it just makes good job with a high brightness Berlinlasers 635nm red laser diode module. It projects high purity and highly visible red laser light from a 635nm red laser diode.
On basis of easy use of a qualified glass coated lens inside highly durable anodized aluminum alloy housing tube, this 635nm red dot laser enables easy installation, good direction and easy reaching of red reference dot projection onto any raw material surface. After correct use of output power and easy mounting, within freely installed distance of 3 meters, it assures no barrier and no mistake use for high tech and industrial precise dot measuring work fields perfectly.
