New Release: Lumispot ELRF-C15-Mini 3KM Mini Laser Rangefinder Module – Eye-Safe & Ultra-Lightweight LRF Solution

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.
