An 808nm bandpass filter is a type of optical filter that selectively transmits light within a narrow range of wavelengths centered around 808 nanometers (nm), while blocking or attenuating light at other wavelengths.

Such filters are commonly used in a variety of applications, including:telecommunications, medical applications and Industrial and scientific applications
