01 Introduction
In recent years, with the emergence of unmanned combat platforms, drones and portable equipment for individual soldiers, miniaturized, handheld long-range laser rangefinders have shown broad application prospects. Erbium glass laser ranging technology with a wavelength of 1535nm is becoming more and more mature. It has the advantages of eye safety, strong ability to penetrate smoke, and long range, and is the key direction of the development of laser ranging technology.
02 Product Introduction
The LSP-LRS-0310 F-04 laser rangefinder is a laser rangefinder developed based on the 1535nm Er glass laser independently developed by Lumispot . It adopts the innovative single-pulse time-of-flight (TOF) ranging method , and its ranging performance is excellent for different types of targets – the ranging distance for buildings can easily reach 5 kilometers, and even for fast-moving cars, it can achieve a stable ranging of 3.5 kilometers. In application scenarios such as personnel monitoring, the ranging distance for people is more than 2 kilometers, ensuring the accuracy and real-time nature of the data. The LSP-LRS-0310F-04 laser rangefinder supports communication with the host computer through the RS422 serial port (TTL serial port customization service is also provided), making data transmission more convenient and efficient.

03 Product Features
* Beam expansion integrated design: efficient integration and enhanced environmental adaptability
The integrated beam expansion design ensures precise coordination and efficient collaboration between the components. The LD pump source provides stable and efficient energy input for the laser medium, the fast axis collimator and focusing mirror accurately control the beam shape, the gain module further amplifies the laser energy, and the beam expander effectively expands the beam diameter, reduces the beam divergence angle, and improves the beam’s directivity and transmission distance. The optical sampling module monitors the laser performance in real time to ensure stable and reliable output. At the same time, the sealed design is environmentally friendly, extends the service life of the laser, and reduces maintenance costs.
