4.5V Dot Laser Diode

 

Laser Diode sends a red dot-shaped light to the area you use. The product cannot be used in laser cutting. It is a laser that can only be used in operations such as zone determination in the work area. 

 

In the ideal situation (no dust, no smoke, no barrier), the laser transmission distance is infinite. In high air quality, the transmission distance can be more than 1KM.  In cloudy night, it can be clearly seen 500 meters away from objects.
