1535nm
Er-Glass Eye-Safe Sensors
The ultimate solution for high-performance ranging. Known for its exceptional eye safety and ability to penetrate complex environmental conditions, making it the top choice for strategic and professional applications.

- Long ranging distance: Capable of reaching several kilometers or even further.
- Strong penetration: Better performance in harsh weather (fog, haze, dust) compared to 905nm.
- High anti-interference: Low solar background radiation at this band, resulting in a higher signal-to-noise ratio during daytime.
- Large size and heavy weight due to complex pump source.
- Higher manufacturing and calibration costs (expensive Erbium glass crystals).
- Relatively lower efficiency with higher heat generation.
Application Scenarios:Military target designators, border defense reconnaissance, and professional UAV payloads where extreme safety and long distance are required.
