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. ERDI TECH still recommends that you avoid looking directly at the rangefinder laser when the laser rangefinder is working to avoid unnecessary personal injury.

2 Ranging capability

In an environment with visibility ≥ 23Km and relative humidity ≤ 60%, when testing a target plate (or other equivalent target) with a reflectance of 0.3 in size 2.3m×4.6m, the laser rangefinder’s ranging capability can reach more than 15,000m. And the accuracy rate is greater than 98%, which is also a key indicator to judge whether the laser range finder is qualified. the relationship between laser rangefinder range and visibility under theoretical conditions. 

TECHNICAL PARAMETERS

Factors such as target reflectivity and measurement angle will impact the ranging capability. Generally, higher target reflectivity enhances the ranging ability, while a more vertical laser angle when irradiating the reflective surface of the measurement target improves ranging performance. In practical applications, it is advisable for the laser rangefinder to illuminate the target surface as vertically as possible. For targets with medium to high reflectivity like traffic signs and others, the laser rangefinder can also exhibit better performance. However, for targets that do not provide diffuse reflection, such as water surfaces, accurate measurements may not be achievable (for water surface measurements requirements, our company offers relevant models; please inquire).

3 Ranging blind area

For targets within 120m, 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 laser range finder, because the laser range finder has strong echoes from targets in the blind zone, which may cause the laser range finder's detector life to be reduced or the ranging capability to be reduced, especially 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 cover the receiving lens.

4 Distance measurement accuracy

For targets with an accuracy rate of ≥98%, the accuracy error of the laser rangefinder can reach within 1.5m. For example, for a target with an actual distance of 1000m, the measurement value of the laser rangefinder will be within 998.5m and 1001.5m.

5 Accuracy rate

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

6 Distance resolution

The minimum resolution distance between the front and rear targets measured by the laser rangefinder is ≤50m.

7 Ranging frequency

The laser rangefinder can achieve single ranging and 1Hz ranging with different frequency requirements by sending different instructions. See 3.2.3 for the corresponding ranging instructions and operating instructions.

8 Product weight

The total weight of the laser rangefinder is ≤596g.

9 Dimensions

144mm×108mm×75mm is the maximum size of the laser rangefinder. Please refer to Figure 2 for the schematic diagram of the overall dimensions.

10 Power supply voltage

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

11 Power consumption

The standby power consumption of the laser rangefinder is ≤2.5W, and the average power consumption is ≤6W. Different working conditions will have a certain impact on the power. Try to keep the laser rangefinder in a safe working environment.

12 Environmental adaptability

The laser rangefinder can operate normally under the conditions of -40℃~+60℃. 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.
