I. NLM8200A 1535nm Coastal Security Laser Rangefinder Module

Engineered for High-Reliability Integration in Severe Environments

The NLM8200A is an advanced 1535nm DPSS Coastal Security Laser Rangefinder Module optimized for long-range target acquisition where signal integrity is paramount. Featuring a massive Φ40.4mm reception lens, the module maximizes photon collection to secure vehicular targets at 8200m and human profiles at 5100m with precise ±1m accuracy.Constructed as a 145g optical core without a secondary chassis, this assembly leverages a differential RS422 interface to maintain zero-latency telemetry even in electromagnetically noisy environments. Its wide operational spectrum of -40℃ to +60℃ and IP67-rated sealing make it the definitive choice for heavy UAV payloads and strategic coastal observation networks requiring uninterrupted performance.
