NTLR-B12000L Laser Rangefinder Module | 15km Long-Range Measurement

1.Overview

The laser ranging module (Model: NTLR-B12000L) is independently developed by Liangdian Optoelectronics, based on a 1535nm erbium glass laser. It adopts the single-pulse TOF (Time of Flight) ranging method, with a maximum measuring range of ≥15 km.

The module is composed of a laser, transmitting optical system, receiving optical system, and control circuit board. It communicates with the upper computer via an RS422 serial port, and is equipped with upper computer testing software and a communication protocol to facilitate secondary development by users. Key features include small size, light weight, stable performance, high impact resistance, and Class 1 eye safety.

2. Structural Composition & Main Functional Indicators

The NTLR-B120000L laser rangefinder consists of a laser, transmitting optical system, receiving optical system, and control circuit. Its main specifications are as follows:

2.1 Operating Distance

Under the conditions of clear view (visibility ≥20 km) and humidity ≤80%:

• For large targets      (e.g., buildings): Ranging distance ≥15 km

• For vehicles      (2.3m×2.3m target, diffuse reflectivity ≥0.3): Ranging distance ≥12 km

• For personnel      (1.75m×0.5m target, diffuse reflectivity ≥0.3): Ranging distance ≥6 km

2.2 Main Functions

a) Single ranging and continuous ranging

b) Distance gating, front and rear target indication

c) Self-inspection function

3. Usage Precautions

1. The laser emitted by      this range finder is a 1535nm eye-safe laser. Although it meets eye safety      standards, direct eye contact with the laser is strictly not      recommended.

2. When adjusting the      parallelism of the optical axis, the receiving lens must be blocked.      Failure to do so may cause permanent damage to the detector due to      excessive echo intensity.

3. The measuring range is      affected by atmospheric visibility and target properties:

• In foggy, rainy, or       dusty conditions, the measuring range will decrease.

• Targets with high       reflectivity (e.g., white walls, exposed limestone) can extend the       measuring range.

• An increased       inclination angle of the target relative to the laser beam will reduce       the measuring range.

4. Strictly prohibit emitting laser      to strong reflective targets (e.g., glass, white walls) within 100      meters—excessive echo may damage the APD detector permanently.

5. Do not plug or unplug      the cable when the device is powered on.

6. Ensure correct power      polarity connection; incorrect polarity will cause permanent damage to the device.
