Frequently Asked Questions (FAQ)
What is the difference between a laser rangefinder and a laser target designator?
A laser rangefinder measures the distance to a target using laser pulses, while a laser target designator illuminates a target with coded laser energy that can be recognized by laser-guided weapon systems. ERDI modules integrate both functions into a single device.
Why is 1064nm commonly used for target designation?
1064nm solid-state lasers provide high pulse energy, excellent beam quality, and compatibility with many laser-guided targeting and fire-control systems, making them a widely adopted solution for military applications.
Which model is suitable for UAV integration?
For lightweight UAV platforms, the LDR20K1, LDR25K1, and LDR40K3 are commonly selected due to their compact size and low weight. Larger UAVs may benefit from higher-energy models such as the LDR60K1, LDR80K1, or LDR100K1.
What is the maximum ranging capability available?
The ERDI 1064nm series includes systems capable of ranging beyond 30km under suitable target and visibility conditions.
Can ERDI provide customized solutions?
Yes. ERDI supports customized configurations based on platform requirements, integration constraints, operational environments, and performance objectives.
What platforms can these systems be integrated into?
ERDI laser rangefinder and target designator modules can be integrated into UAVs, EO/IR payloads, surveillance towers, tactical vehicles, naval systems, and other defense or security platforms.
