1535nm Laser Rangefinder Module 5000m SFB5000L

The SFB5000L laser ranging module is independently developed by our company, based on a 1535nm erbium glass laser, and adopts the single-pulse TOF (Time of Flight) ranging method.
Composed of a laser, a transmitting optical system, a receiving optical system, and a control circuit board, this laser ranging module communicates with the host computer via a TTL serial port (RS422 serial port can be customized). It also provides host computer testing software and a communication protocol, facilitating users’ secondary development.
Featuring small size, light weight, stable performance, high impact resistance, and Class 1 eye safety, it can be applied to optoelectronic devices such as handheld devices, vehicle-mounted devices, and pods.
