Three common 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 the most widely used laser rangefinder at present. Functionally, in addition to measuring the distance, it can also generally calculate the volume of the measured object.
2. Cloud service laser range finder
The measurement data on the laser range finder is 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 wifi networking, and the measurement data can be shared in real time with remote construction partners.
3. Telescopic laser range finder
The measurement distance is relatively long, and the general measurement range is about 3.5 meters to 2000 meters. There are also ranging telescopes with a maximum range of about 10 kilometers. Due to the collimation requirements of the ranging telescope, the blind area is below 3.5 meters, and the laser is greater than 2000 meters Telescopes generally use YAG lasers 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.
