High-Performance 1535nm Erbium Glass Eye-Safe Laser Rangefinder Sensors

Mission-Critical DPSS Telemetry for Aerospace, Security, and Industrial Integration

Our premier 1535nm Erbium Glass laser rangefinder portfolio, encompassing 24 specialized OEM/ODM models within the NTLRA and NTLRB series, is meticulously engineered for mission-critical reliability across aerospace, strategic security, and high-precision industrial sectors. Utilizing proprietary Diode-Pumped Solid-State (DPSS) technology, these sensors deliver unparalleled measurement accuracy with Class 1 Eye-Safety certification and a specialized invisible wavelength for highly secure remote operations. Designed to excel in high-altitude aerospace payloads and harsh field environments, our sensors are built to withstand 150g-1200g shocks and operate seamlessly within a -40°C to +70°C temperature range. From ultra-lightweight 17g–32g micro-UAV integrated cores for altitude hold to heavy-duty 840g strategic units with 20km detection capabilities, the series provides superior atmospheric penetration through fog, haze, and dust. These high-end sensors ensure precise automated distance detection for UAV tracking, strategic border monitoring, coastal surveillance, advanced precision sighting platforms, and high-frequency industrial robotics for AGV navigation and 3D structural mapping.
