Description
The new LM Mini series of miniature laser rangefinder modules is developed based on our self‑developed 1,535 nm erbium‑glass laser, and it is a Class 1 eye‑safe product. The product has significant advantages in size and weight, supporting a measurement range of 10‑4,000 m, with a detection range of up to 3,000 m for vehicle targets. Compared with the previous‑generation 1535 nm rangefinder module of the same measuring range, the size has been reduced by 66% and the weight by 56%. While achieving ultimate miniaturization and lightweight design, this product further reduces power consumption and features stable performance and high shock resistance.


The module supports functions such as single measurement, continuous measurement, first/last target, and multi‑target ranging. It can be widely used in civilian UAVs, outdoor observation, and security applications.
