1550nm Narrow Band Filter

1550nm narrow band filter for lidar

1550nm narrow-band infrared filter is widely used in emerging fields such as optical fiber external detection, machine vision light source, water quality detection, driverless vehicle lidar and so on.

At present, 1550nm narrow-band filter is widely used in unmanned lidar applications. Compared with 905nm filter, 1550nm filter can improve higher laser power and higher safety to human eyes.
