Laser rangefinder telescope, a precision instrument, uses laser technology to accurately measure the distance of the target. Its working principle is to emit a very fine laser beam to the target and receive the laser beam reflected by the target through a photoelectric element. The built-in timer function is used to measure the time required from the emission to the reception of the laser beam, and then calculate the distance between the observer and the target.
The laser emission mode of the laser rangefinder telescope is pulsed. Although its absolute accuracy is relatively low, it performs well in long-distance measurement and can achieve high relative accuracy. Its measurement accuracy can usually reach +/-1 meter, and the measurement distance range is wide, ranging from 500 meters to 4000 meters.
Application field
Laser rangefinder telescope has a wide range of applications in many fields. Its accuracy is particularly outstanding in terrain measurement and battlefield measurement. At the same time, it is also used for tanks, aircraft, ships and artillery to accurately measure the distance of targets, as well as to measure the height of clouds, aircraft, missiles and artificial satellites. This technical equipment is crucial to improving the combat accuracy of tanks, aircraft, ships and artillery. In recent years, as the price of laser rangefinder telescopes has become more affordable, laser rangefinders have also been widely used in the industrial field, and their practicality in industrial measurement and control, mines and ports has become increasingly apparent.
Working principle
Laser rangefinder telescopes mainly use the pulse method to measure distance. Its working process is: the rangefinder emits laser, which is reflected by the object to be measured and then received by the rangefinder. In this process, the rangefinder will synchronously record the round-trip time of the laser. By multiplying the speed of light by the round-trip time and then dividing it by 2, the distance between the rangefinder and the object to be measured can be obtained. Generally, the accuracy of pulse method distance measurement can reach about +/- 1 meter. At the same time, this type of rangefinder has a measurement blind spot of about 15 meters.
Purchase guide
When choosing a laser rangefinder telescope, there are several key points worth careful consideration:
It is recommended to purchase genuine products.
The measurement distance of a laser rangefinder telescope is one of its core performances, but it should be noted that the actual measurement distance will be affected by many factors, including the measurement environment and the conditions around the target. Therefore, the measurement distance specified by the manufacturer is only a theoretical value, which may differ in actual use.
After determining the brand, the laser rangefinder telescope with the appropriate measurement distance should be selected according to personal actual needs. Generally, the farther the measurement distance, the higher the product price.
Regarding the measurement accuracy, the theoretical accuracy of laser rangefinder telescopes of various manufacturers is usually ±1 meter. However, in actual use, due to differences in lens quality, laser receiver quality and data processor accuracy, the actual measurement results may vary.
In addition, the onick 600AS laser rangefinder we displayed is a 600-meter laser rangefinder telescope. It integrates the dual functions of ordinary telescopes and laser rangefinders. It can be used to observe domestic objects and quickly measure the distance of objects within a certain distance range. Its ranging time is fast, the distance display is intuitive and power-saving, and it will automatically power off when not in use, ensuring safe and convenient use.
The laser emission power of this rangefinder telescope is moderate and harmless to human eyes. It can measure the distance of any object without a cooperative target. Its small size and light weight make it very convenient to carry. In addition, the built-in 3V battery is easy to replace, which brings great convenience to users.
When used in rainy days, the "RAIN" mode can ensure that the distance measurement is not affected; and the ">150" mode can effectively eliminate the interference of small targets such as close-range wires and branches on the distance measurement. Therefore, the laser rangefinder telescope is not only suitable for distance measurement in outdoor sports activities such as golf and hunting, but also can be used for general topographic measurement and distance measurement of power poles.
