Three main points of a telescope rangefinder
overview
Telescope rangefinder is a branch of laser rangefinder, or called long-distance laser rangefinder. Generally its ranging distance is 500-3000 meters. The telescopic range finder adopts the pulse method for distance measurement, so its measurement blind area is about 15 meters. The measurement error is +/-1 meter.
principle
Telescope rangefinders generally use the pulse method to measure distance. The process of pulse method ranging is as follows: the laser emitted by the range finder is reflected by the measured object and then received by the range finder, and the range finder records the time of the laser back and forth at the same time. Half of the product of the speed of light and the round-trip time is the distance between the rangefinder and the measured object. The accuracy of distance measurement by pulse method is generally around +/-1 meter. In addition, the measurement blind zone of this type of rangefinder is generally about 15 meters.
Shopping points
1. The basic parameter of the telescope range finder is the measurement distance. The first step should be to choose the telescope rangefinder that you need to measure the distance.
2. Measurement accuracy, the nominal measurement accuracy of all manufacturers is +/-1 meter, which is only theoretical data. The measurement accuracy depends on the measurement target environment, the telescope rangefinder lens, the quality of the infrared laser transmitter, and the accuracy of the data processor.
At present, the brands that use lenses on the market are Tuyad and Nikon. This is also one of the reasons why they can become the North American sales champion and runner-up.
