1 Working band

When the laser rangefinder is working, the ranging laser is in the 1535nm ± 10nm band. The laser beam is invisible to the naked eye and is in the human eye-safe band. It is still recommended to avoid looking directly into the rangefinder laser when the rangefinder is working to avoid unnecessary personal injury.

2 Ranging capability

In an environment with visibility ≥10Km and humidity ≤60%, the laser rangefinder's ranging capability can reach more than 10,000m for testing on a 2.3m×4.6m standard target plate or equivalent target, and the accuracy rate is greater than 98%. It is also a key indicator to judge whether the distance measurement capability of the laser range finder is qualified.  the relationship between laser rangefinder range and visibility under theoretical conditions.                            

Factors such as target reflectivity and measurement angle will affect the ranging capability. Generally, the higher the target reflectivity, the better the ranging ability; the more vertical the laser angle is when it irradiates the measurement target reflective surface, the better the ranging ability. In practical applications, the rangefinder laser should be irradiated vertically onto the target surface as much as possible. For targets with medium and high reflectivity, such as traffic signs, the laser rangefinder can also perform better. However, for targets that are difficult to form diffuse reflection, such as water surfaces, the laser rangefinder may not be able to accurately measure (for water surface measurement needs, our company has relevant models to meet, please inquire).

3 Ranging blind area

For targets within 50m, the laser rangefinder may not be able to accurately measure, which is its ranging blind spot. It is not recommended that users test targets in the blind zone of the rangefinder, because the laser rangefinder has a strong echo to the target in the blind zone, which may cause the laser rangefinder's detector life to be reduced or the ranging capability to be reduced, especially for Testing high-reflectivity targets in the blind zone may even cause permanent damage to the detector. Therefore, when the laser rangefinder is under close working conditions such as debugging, please block the receiving lens.

4 Distance measurement accuracy

For targets with an accuracy rate of ≥98%, the average accuracy error of the laser rangefinder can reach within 1m. For example, for a target with an actual distance of 1000m, the measurement value of the laser rangefinder will be within 999m and 1001m.

5 Accuracy rate

The accuracy rate of the laser rangefinder is greater than 98%.

6 Ranging frequency

The laser rangefinder can achieve three different frequency requirements: single ranging, 1Hz ranging, and 5Hz ranging by sending different instructions. See 1.5 for the corresponding ranging instructions and operating instructions.

7 Product weight

The total weight of the laser rangefinder is ≤290g.

8 Dimensions

The maximum overall size of the laser rangefinder is ≤107mm×84mm×56mm.

9 Power supply voltage

The power supply voltage of the laser rangefinder is 18V~36V.

10 Power consumption

The average power consumption of the laser rangefinder: ≤5W, standby power consumption: ≤1.8W. Different working conditions will have a certain impact on the power. Try to keep the rangefinder in a safe working environment.

11 Environmental adaptability

The laser rangefinder can operate normally under the conditions of -40℃~+60℃, and the storage temperature range is -55℃~+70℃. It is recommended that the laser rangefinder be operated or stored in a normal temperature and dry environment. Too high or too low temperature may cause the decline of certain index capabilities of the laser rangefinder. In particular, avoid using the laser rangefinder when the temperature changes drastically. If used in an environment, this may reduce the service life of the laser rangefinder or cause malfunction. The laser rangefinder was designed with possible temperature shocks in mind, but our company does not guarantee the performance under these conditions.

ELECTRICAL INTERFACE

The electrical interface requirements are as follows:

  • Power supply voltage: 18V~36V;
  • Average power consumption ≤5W;
  • Standby power consumption: ≤1.8W;
  • The host computer uses the J30J-9ZKL connector to achieve cross-linking with the rangefinder J30J-9TJP connector. The pin definitions of the power supply and communication port of the host computer are shown in Table 1 (receiver and transmitter are relative to the range finder), and the position of connector pin 1 is shown .
