In order to make highly clear and accurate dot alignment at long work distance, it is far more enough to reach with a simple laser pointer for temporary dot positioning work, it makes good job with Berlinlasers 445nm blue laser diode module. It adopts 5V, 9V 1000mA DC power supply as electric power source, it projecting highly visible blue laser light at several miles, but also makes good job for highly clear dot alignment at long distance and formal lighting occasion.

On basis of the use of durable anodized aluminum alloy housing with 16mm diameter tube, this 445nm blue dot laser just enables easy installation, convenient dot projection onto any raw material surface. Only if it makes freely adjusted laser beam focus, it assures no mistake use for all precise dot measuring work fields perfectly.
