Advantages OF Narrow Bandpass Optical Filter

High selectivity: Narrow bandpass filters can selectively pass light in a small wavelength range across a wide spectrum, which is particularly useful for applications that require the exclusion of background noise or interfering light.

Central wavelength: Each narrow bandpass filter has a specific central wavelength, which is the wavelength position of the maximum transmittance it is designed to pass.
