The range of the Laser pointer refers to how far the laser of the laser pointer can shoot. The range of the laser pointer refers to the laser distance, most of which are above 200 meters. The range of the laser pointer is also related to the power of the laser pointer. The greater the power, the longer the range Far. The remote control distance of the laser pointer refers to the distance between the laser pointer transmitter and the receiver. Generally, the remote control distance of the laser pointer is 10 meters, 15 meters, 20 meters, etc. At the same time, it has automatic frequency hopping technology, which can effectively avoid other radio frequency signals. interference.

Three factors affecting the range of the laser pointer:
1. Power, the greater the power, the farther the irradiation.
2. Air quality, the less particulate matter, the smaller the beam attenuation, and the farther the beam can be shot.
3. The smaller the beam divergence, the farther the beam will be shot. Example: A red light (wavelength 650nm) laser pointer with a power of 200mW, under a clear night sky in summer (the air quality is very good), illuminate the cloud, and you can see the red light spot on the cloud. With 50mW of green light, expand the thick beam (reduce the divergence), and people from 3 kilometers away can see the light spot. The premise also requires good air quality.
