What is the accuracy of a laser rangefinder?

The accuracy of laser rangefinders varies depending on the model, purpose and measurement conditions. The following is a detailed analysis of the accuracy of laser rangefinders:

1. Handheld laser rangefinders

The measurement distance of handheld laser rangefinders is generally within 200 meters, and its accuracy is usually around 2mm. This type of rangefinder has been widely used in home decoration, indoor measurement and other fields due to its portability and high accuracy.

2. Telescope laser rangefinder

The measurement distance of telescope laser rangefinders is relatively long, generally around 600 meters to 3000 meters, and the measurement distance of some high-end products can even reach 10 kilometers or more. However, due to the increase in its measurement distance, its accuracy is relatively low, generally around 1 meter or less. This type of rangefinder is usually used in the fields of long-distance measurement, topographic mapping and other fields.

3. Pulse laser rangefinder

The pulse laser rangefinder calculates the distance by emitting a short pulse laser beam and measuring its round-trip time. When the emitted laser beam power is sufficient, the measurement range can reach about 40 kilometers or even farther. The accuracy of pulsed laser rangefinders is generally around ±10 cm, but the accuracy of entertainment-grade products may be lower, while the accuracy of measurement-grade products is relatively high.

4. Phase-type laser rangefinder

Phase-type laser rangefinders calculate distance by measuring the phase difference of the laser beam, and their accuracy can reach 1 mm error or even higher. This type of rangefinder is usually used for various high-precision measurement purposes, such as industrial automation, precision manufacturing and other fields.
