For the development of optoelectronic payloads, drone pods, and portable observation devices, achieving long-distance ranging, stable performance, and high environmental adaptability while maintaining ultra-small size, light weight, and low power consumption has always been a core challenge for system integrators. Most conventional long-range laser rangefinder modules deliver qualified ranging performance but feature bulky size and heavy weight, limiting their application in space-constrained compact equipment.
Lumispot officially launches the brand-new ELRF-C15-Mini 3KM Laser Rangefinder Module, a high-performance mini LRF built on self-developed 1535nm erbium-doped laser technology. Adopting the single-pulse Time-of-Flight (TOF) ranging principle, this highly integrated module balances excellent SWaP (Size, Weight, Power) metrics and reliable multi-target long-distance ranging capability, providing an optimal core ranging solution for lightweight optoelectronic systems.
1. Product Overview & Hardware Advantages
The ELRF-C15-Mini laser rangefinder module integrates a self-developed laser transmitter, transmitting optical system, Φ15mm receiving optical system, and control circuit board into an ultra-compact structure. With dimensions of≤27.5×15.9×24.6mm and a lightweight weight of 15g±1g, it imposes almost no load burden on the carrier platform and can be easily embedded in micro drone pods, handheld optoelectronic devices, vehicle-mounted photoelectric systems, and mini reconnaissance equipment.
Equipped with a standard TTL 3.3V serial port (default baud rate: 115200bps) and a dedicated 6P connector, the module supports complete secondary development. Lumispot provides matching upper computer test software, official communication protocols, and online firmware upgrade functions, greatly shortening the customer’s R&D and integration cycle. It supports a wide DC input voltage range of 5V to 24V, compatible with various power supply scenarios such as battery power and vehicle-mounted power systems.
2. Core Ranging Performance & Functional Features
Featuring a 1535±5nm laser wavelength and Class 1 eye-safe level, the module ensures zero harm to human eyes during normal use, meeting civilian and industrial safety standards. Under standard working conditions (visibility ≥12km, humidity ≤80%), it delivers stable and excellent ranging capability for different target types:
- • Building target (60% reflectivity): ≥4000m
- • Vehicle target (2.3×2.3m, 30% reflectivity): ≥3000m
- • Human target (0.5×1.7m, 30% reflectivity): ≥2000m
- • UAV tiny target (0.2×0.3m, 30% reflectivity): ≥1000m
Key technical indicators guarantee high-precision and high-stability measurement:
- • Minimum ranging distance: ≤10m
- • Ranging accuracy: ≤±1m
- • Measurement frequency: 1~10Hz (adjustable)
- • Distance resolution: ≤20m
- • Measurement accuracy rate: ≥98%
- • False alarm rate: ≤1%
In terms of functions, the module supports single ranging, continuous ranging, multi-target ranging, range gating, and self-test functions. It can capture multiple echo signals simultaneously and output accurate distance data of different targets, adapting to complex and variable field measurement scenarios.
3. Low Power Consumption & Superior Environmental Reliability
Aiming at the complex working conditions of vehicle-mounted, airborne, and portable devices, the ELRF-C15-Mini is optimized for power consumption and environmental adaptability, ensuring stable operation in extreme environments.
3.1 Power Consumption Performance
- • Average power consumption: ≤0.9W @5V (1Hz operation); ≤1.5W @5V (10Hz operation)
- • Peak power consumption: ≤3W @5V
- • Standby power consumption: ≤0.3W @5V (Power ON high level); ultra-low power ≤1mW @5V (Power ON low level)
The ultra-low standby power design effectively saves the power consumption of the carrier device, greatly improving the endurance of battery-powered equipment such as drones and handheld devices.
3.2 Environmental Adaptability
- • Operating temperature: -40℃～+70℃
- • Storage temperature: -55℃～+75℃
- • Impact resistance: ＞75g@6ms
- • Vibration resistance: compliant with combined wheeled vehicle vibration environment
It can resist severe temperature changes, strong impact and vibration, maintaining consistent ranging performance in harsh outdoor, vehicle-mounted and airborne scenarios.
4. Application Scenarios
Benefiting from its ultra-compact size, light weight, eye safety, low power consumption and high reliability, the ELRF-C15-Mini laser rangefinder module is widely applicable to various lightweight optoelectronic systems:
- • UAV Optoelectronic Pods: Real-time target ranging, auxiliary positioning and tracking for micro drone payloads
- • Handheld Observation Devices: Night vision observers, portable sighting and distance measurement equipment
- • Vehicle-Mounted Optoelectronic Systems: Short and medium-range target distance perception for vehicle reconnaissance devices
- • Mini Reconnaissance Equipment: Space-limited optoelectronic equipment integration and secondary OEM development
5. Product Summary
The Lumispot ELRF-C15-Mini perfectly solves the industry pain point of “difficulty in balancing long-distance ranging and miniaturization”. It integrates 4km-level long-range ranging, Class 1 eye safety, ultra-low power consumption and strong environmental resistance in a 15g ultra-small module. With complete secondary development interfaces and convenient firmware upgrade functions, it greatly reduces the integration threshold for equipment manufacturers.
As an upgraded miniaturized LRF solution, it is the ideal core ranging sensor for new-generation lightweight drone pods, portable optoelectronic devices and vehicle-mounted reconnaissance systems.
