The 1550nm wavelength is a popular choice in LiDAR systems due to its advantages in range and performance. Its longer wavelength, in contrast to the 905nm option, allows for better penetration of dense fog, dust, and other atmospheric particles. This capability makes it particularly suitable for applications where visibility is compromised, such as autonomous driving in adverse weather conditions.
Conversely, the 905nm wavelength is frequently used in shorter-range LiDAR systems. It performs well in clear atmospheric conditions and is commonly employed in applications such as robotics, industrial automation, and indoor mapping.
