The BP1550nm narrowband filter for laser radar is mainly used in emerging fields such as infrared driverless car LiDAR, including automotive head-up display HUD, Laser radar scanning and ranging applications. This infrared filter can allow infrared light of a specific wavelength (i.e. 1550nm) to pass through while blocking light of other wavelengths, thereby improving the performance and accuracy of laser radar. It helps laser radar to more effectively collect and analyze information in the environment, achieving more accurate target detection and distance measurement. In addition, infrared light in the 1550nm band has the characteristics of strong penetration, not easily affected by scattering of particles in the atmosphere, and relatively high safety for human eyes, which makes the BP1550nm narrowband filter have significant advantages in applications such as driverless cars.

andpass filters are filters with cut-off bands adjacent to the transmission bands on both sides of the spectral characteristic curve. Bandpass filters are roughly divided into two types according to spectral characteristics: broadband filters and narrowband filters. The two types of filters are usually combined. The principle of light wave interference is applied to prepare bandpass filters, and bandpass filters have been widely used in various fields.
