1535nm Laser Rangefinder Module Eye-safe Long Distance Laser Ranging Sensor 25KM

1535nm Laser Rangefinder Module Eye-safe Long Distance Laser Ranging Sensor 25KM

Model: LRF2535C-01
The LRF2535C laser rangefinder module is a high-performance long-range laser distance sensor module, designed for precise measurements over extended distances. With a wavelength of 1535nm and Class I eye safety, it can accurately measure up to 28,000 meters for large targets and 25,000 meters for vehicle-sized targets. This makes it ideal for applications requiring extreme range capabilities, such as military surveillance, aerospace, defense, and geospatial surveying and mapping. This compact 1535nm rangefinder module also offers reliable performance for detecting drones (up to 2,500 meters) and people (up to 4,800 meters). The high-precision 1535nm laser module features ±1m accuracy, high precision, and supports multi-target detection. Its robust design ensures effective operation in extreme temperatures, making it highly versatile for demanding long-range applications.

The LRF2523C laser rangefinder module is a long-range device developed by Erdi, utilizing their independently developed 1535nm glass laser. It employs the single-pulse Time of Flight (TOF) ranging principle, achieving a range of ≥25km for targets measuring 4m×6m.

This laser rangefinder module integrates key components including a laser source, transmitting optical system, receiving optical system, and a control circuit board. For user convenience and secondary development, it features an RS422 serial interface and embedded software.

The LRF2523C offers comprehensive functions such as single and continuous ranging, three-target ranging capability, and a self-check function for front/rear target indication (reporting current APD temperature, high voltage value, internal voltage, and blind zone value). It also includes a standby wake-up function.
