1535NM 3KM LASER RANGEFINDER MODULE
Product Introduction
The LSP-LRS-0310F laser rangefinder is a laser rangefinder developed based on the 1535nm Er glass laser independently developed by Liangyuan Laser. Adopting an innovative single pulse Time of Flight (TOF) ranging method, the ranging performance is excellent for different types of targets - the ranging distance for buildings can easily reach 5 kilometers, and even for fast-moving cars, stable ranging of 3.5 kilometers can be achieved. In applications such as personnel monitoring, the ranging distance for people exceeds 2 kilometers, ensuring the accuracy and real-time performance of data. The LSP-LRS-0310F-04 laser rangefinder supports communication with the upper computer through RS422 serial port (while providing TTL serial port customization service), making data transmission more convenient and efficient.

Product Features
● Beam Expander Integrated Design: Enhanced Environmental Adaptability through Integration Efficiency
The beam expander integrated design ensures precise coordination and efficient collaboration among components. The LD pump source provides stable and efficient energy input to the laser medium, while the fast-axis collimating lens and focusing lens precisely control the beam shape. The gain module further amplifies the laser energy, and the beam expander effectively expands the beam diameter, reducing the beam divergence angle and enhancing beam directionality and transmission distance. The optical sampling module monitors laser performance in real-time to ensure stable and reliable output. Additionally, the sealed design is environmentally friendly, extending the laser's lifespan and reducing maintenance costs.
● Segmented Switching Ranging Method: Precision Measurement for Enhanced Ranging Accuracy
Centered on precision measurement, the segmented switching ranging method utilizes optimized optical path design and advanced signal processing algorithms, combined with the laser's high-energy output and long-pulse characteristics, to successfully penetrate atmospheric disturbances, ensuring stability and accuracy in measurement results. This technology adopts a high-repetition-frequency ranging strategy, continuously emitting multiple laser pulses and accumulating processed echo signals, effectively suppressing noise and interference, significantly improving the signal-to-noise ratio, and achieving precise measurement of target distances. Even in complex environments or facing subtle changes, the segmented switching ranging method guarantees measurement accuracy and stability, becoming an essential technical approach to enhancing ranging precision.
● Dual-Threshold Scheme for Ranging Accuracy Compensation: Double Calibration for Beyond-Limit Precision
The dual-threshold scheme's core lies in its dual calibration mechanism. The system initially sets two distinct signal thresholds to capture two critical moments of the target echo signal. These moments slightly differ due to the different thresholds, but this difference serves as the key to compensating for errors. Through high-precision time measurement and calculation, the system accurately determines the time difference between these two moments and uses it to finely calibrate the original ranging result, significantly enhancing ranging accuracy.
● Low-Power Design: Energy-Efficient and Performance-Optimized
Through deep optimization of circuit modules such as the main control board and driver board, we have adopted advanced low-power chips and efficient power management strategies, ensuring that the system's power consumption is strictly controlled below 0.24W in standby mode, representing a significant reduction compared to traditional designs. At a ranging frequency of 1Hz, the overall power consumption remains within 0.76W, demonstrating an exceptional energy efficiency ratio. Even under peak operating conditions, while power consumption increases, it is still effectively controlled within 3W, ensuring stable device operation under high-performance demands while maintaining energy-saving goals.
● Extreme Condition Capability: Superior Heat Dissipation for Stable and Efficient Performance
To address high-temperature challenges, the LSP-LRS-0310F laser rangefinder employs an advanced cooling system. By optimizing internal heat conduction paths, increasing heat dissipation area, and utilizing efficient thermal materials, the product efficiently dissipates internally generated heat, ensuring that core components maintain an appropriate operating temperature even during prolonged high-load operation. This superior heat dissipation capability not only extends the product's lifespan but also guarantees the stability and consistency of ranging performance.
● Balancing Portability and Durability: Miniaturized Design with Exceptional Performance
The LSP-LRS-0310F laser rangefinder boasts an astonishingly small size (just 33 grams) and lightweight design, while simultaneously offering stable performance, high shock resistance, and Class 1 eye safety, demonstrating a perfect balance between portability and durability. This product's design embodies a profound understanding of user needs and a high degree of technological innovation, making it a standout focus in the market.

Product application areas
▶ The laser emitted by this ranging module is 1535nm, which is safe for human eyes. Although it is a safe wavelength for human eyes, it is recommended not to stare at the laser;
▶ When adjusting the parallelism of the three optical axes, be sure to block the receiving lens, otherwise the detector may be permanently damaged due to excessive echo;
▶ This ranging module is non-hermetic, so it is necessary to ensure that the relative humidity of the use environment is less than 80%, and the use environment should be kept clean to avoid damaging the laser;
▶ The measuring range of the ranging module is related to atmospheric visibility and the nature of the target. The measuring range will be reduced in fog, rain, and sandstorms. Targets such as green foliage, white walls, and exposed limestone have good reflectivity, which can increase the measuring range. In addition, when the inclination angle of the target to the laser beam increases, the measuring range will be reduced;
▶ It is strictly forbidden to emit laser towards strong reflective targets such as glass and white walls within 5 meters, so as to avoid too strong echo and damage to the APD detector;
▶ It is strictly forbidden to plug and unplug cables when the power is on;
▶ Be sure to ensure that the power polarity is connected correctly, otherwise the equipment will be permanently damaged.
