In the rapidly evolving landscape of UAV integration and professional electro-optical (EO) systems, the "SWaP" requirement—Size, Weight, and Power—is the ultimate benchmark. Today, ERDI Tech is proud to introduce the LRF0305C, an ultra-compact 1535nm eye-safe laser rangefinder module that sets a new standard for performance in its weight class.
Why 1535nm Technology?
Unlike traditional 905nm or 1064nm lasers, the 1535nm wavelength (Erbium-doped glass laser) offers several critical advantages for professional and tactical applications:
- Absolute Eye Safety: Classified as Class 1 (IEC 60825-1), it is safe for the human eye under all conditions.
- Atmospheric Penetration: It outperforms shorter wavelengths in smoke, fog, and hazy environments, ensuring reliable ranging when it matters most.
- Low Probability of Detection (LPD): The 1535nm signal is invisible to standard night vision devices (NVDs), making it ideal for stealth-focused UAV gimbals.
Breaking the Weight Barrier: Only 14g
The most striking feature of the LRF0305C is its weight. At just 14g, it is one of the lightest 4,000m rangefinders on the market. Its compact dimensions (27x25x15.5mm) allow it to be integrated into the smallest drone pods, micro-gimbals, and handheld thermal imagers without compromising the platform's flight endurance or ergonomics.
