PRODUCT DESCRIPTON
ERDI LASER® LDR25K1 is a 1064 nm laser designator and rangefinder module for UAVs, EO/IR gimbals, and compact targeting systems. It supports single-shot and continuous ranging, frequency-coded laser designation, and first/last target logic, providing reliable distance measurement and target illumination for guided weapon and cooperative engagement applications. The module is optimized for airborne integration with a compact form factor, controlled power consumption, and stable operation across wide environmental conditions.
Key Advantage
- High pulse energy：≥25 mJ output enables long-range ranging and effective target designation.
- Precision output： Low beam divergence and stable optical axis ensure accurate illumination.
- Weapon-system coding： Precise frequency coding with user-defined expansion.
- Airborne-ready design： Compact, lightweight, wide voltage input, and harsh-environment capable.
