1535nm DPSS Laser Rangefinder Module

ERDI LASER® Eye-Safe Laser Rangefinder Module develops and manufactures Class 1 eye-safe laser rangefinder modules based on proprietary erbium glass laser technology. Utilizing time-of-flight (TOF) measurement principle, these modules deliver accurate distance calculation by emitting laser pulses toward targets and measuring their round-trip travel time. Engineered for seamless OEM integration, our modules feature compact form factor, high measurement accuracy, exceptional environmental robustness and flexible communication interfaces. With a comprehensive product portfolio covering ranging distances from 3km to over 18km, we provide tailored solutions to meet diverse mission requirements. Operating at the eye-safe 1535nm wavelength, ERDI rangefinders ensure reliable long-distance performance even in harsh operational conditions. They are ideally suited for UAV payloads, EO/IR systems, reconnaissance platforms, border security, military observation equipment, and airborne, ground-based and maritime surveillance systems.
