PRODUCT DESCRIPTON
The ERDI LASER® LRF0305C Compact Laser Rangefinder is based on ERDI’s self-designed MINI-100 erbium glass laser and engineered for high-precision distance measurement in demanding applications such as UAVs, electro-optical pods, and portable observation systems. This model supports an adjustable ranging frequency of 1–10Hz, offering faster measurement speed for real-time applications while maintaining reliable accuracy.
Key Advantages
-
Eye-safe 1535nm TOF technology for precise distance measurement up to 3–4km.
-
Compact and lightweight design (≤14g), ideal for UAV integration and portable devices.
-
Adjustable 1–10Hz ranging frequency for high-speed measurement requirements.
-
Low power consumption with ±1m accuracy.
-
Supports multi-target detection, first/last target recognition, and continuous ranging modes.
