What are the types of laser rangefinders?
1. Handheld laser range finder
The measurement distance is generally within 200 meters, and the accuracy is about 2mm. This is a laser rangefinder that is widely used at present. In addition to measuring the distance, it can also calculate the volume of the measured object.
2. Cloud service laser range finder
The measurement data on the laser rangefinder can be transmitted to mobile terminals such as mobile phones and tablet computers in real time through Bluetooth; the data can be transmitted to the cloud server through if networking, and the measurement data can be shared with remote construction partners in real time.
3. Telescope laser rangefinder
The measurement distance is relatively long, the general measurement range is about 3.5 meters to 2000 meters, and there are also range-finding telescopes with a maximum range of about 10 kilometers. According to the collimation requirements of the range-finding telescope, the blind area is below 3.5 meters, and the range is greater than 2000 meters. Laser telescopes generally use YAG laser with a wavelength of 1.064 microns. In order to achieve a larger measurement range, the laser power is relatively high. Users are advised to pay attention to laser protection. The main application range is outdoor medium and long distance measurement. In addition, it can also be divided into one-dimensional laser range finder: for distance measurement and positioning; two-dimensional laser range finder: for contour measurement, positioning, area monitoring and other fields; three-dimensional laser range finder: for three-dimensional contour measurement , three-dimensional space positioning and other fields.
