Avia 2

Further Reach, Finer Details

Avia 2, Livox's new ultra-long range LiDAR. Powered by a 1535nm laser ^[1], it reaches a maximum cutoff range of 1000 m ^[2] and supports switching between large and small FOVs. With a micro laser spot, as well as the built-in rain and fog noise removal algorithm, Avia 2 can stably capture high-resolution 3D point clouds in complex conditions, revealing rich details.

Ultra-Long Kilometer-Range Detection ^[2]

^{Avia 2 features a 1535nm laser [1], which offers more concentrated energy and a smaller spot size for a massive range increase. It can detect targets of 5% reflectivity 400m away (equivalent to approx. 600m@10% reflectivity) in Normal mode, and targets of 10% reflectivity 800m away in Focus mode, with a maximum cutoff range of 1000 m [2]. A single device covers ultra-long distances. This significantly reduces deployment costs.}

1. The 1535nm laser belongs to the broader 1550nm (1.5μm) eye-safe spectrum. It delivers equivalent physical properties, Class 1 eye safety, and long-range sensing capabilities to those of a 1550nm laser.

2. In Normal mode, Avia 2 has a maximum detection potential of 600 m at 10% reflectivity. However, to ensure a stable output of 350,000 points per second (350 kHz point rate), Avia 2 optimizes the balance between time of flight and measurement rate, and locks the cutoff range of this mode at 400 m to achieve higher point cloud density and consistency within commonly used ranges. In Focus mode, the maximum detection potential at 10% reflectivity reaches 800 m, and the cutoff range in this mode is 1000 m. The 1000m cutoff range is measured against a target with 20% reflectivity, and requires sufficient point cloud integration time depending on the target size in practical applications. Measured in a controlled environment. Results may vary depending on the environment and actual use.

3. The beam divergence is calculated in a laboratory environment by capturing the laser spot with an infrared camera and factoring in the test distance. The spot diameter at 100 m is a theoretical value derived from this divergence. Actual performance may vary slightly depending on ambient temperature and atmospheric conditions.

4. The 62,500 hours is a typical MTTF value calculated using a reliability formula and confidence level, based on high-temperature aging test results in a controlled environment. It does not represent the actual continuous operating time. Continuous operation in extreme environments with high temperature and humidity, or salt spray corrosion, may shorten the product's lifespan and potentially degrade its detection range and overall reliability.

5. The rain and fog noise removal feature includes two sub-functions: the rain noise removal function and the fog noise removal function. The rain noise removal function is only designed for light to medium rain and can effectively filter out most raindrop noise. Actual noise reduction results may vary depending on the environment. For weather conditions such as fog, haze, snow, and hail, please configure the rain and fog noise removal feature as needed based on the environment to achieve optimal results.

6. The ambient temperature range is measured in a controlled environment. The actual tolerance temperature and operating status during use may vary depending on specific on-site conditions (such as ventilation and sunlight). Please refer to the actual on-site conditions for performance.

7. During deployment and operation, please avoid pointing external strong lasers with a wavelength around 1535 nm directly at the LiDAR. Additionally, do not aim the LiDAR at highly reflective targets such as Low-E glass or corner cube retroreflectors at close range. This is to prevent high-intensity light waves from entering the receiver and causing permanent damage to the internal sensors.
