Micro 5KM Laser Rangefinder Module
Product Description
The ELRF-F21 laser rangefinder module is a laser ranging module developed based on Lumispot's independently researched and developed 1535nm erbium laser. It adopts a single-pulse Time-of-Flight (TOF) ranging method with a maximum ranging distance of ≥6km(@large building). Composed of a laser, transmitting optical system, receiving optical system, and control circuit board, it communicates with the host computer through a TTL serial port. It provides host computer test software and communication protocols, facilitating user secondary development. It boasts features such as small size, light weight, stable performance, high shock resistance, and Class 1 eye safety.
