NBP460nm narrowband filter

Working principle of narrowband filter:
Narrowband filters are further subdivided from the same bandpass as bandpass filters, allowing light signals to pass through a specific frequency band and blocking light signals on both sides outside of that band. The passband of narrowband filters is relatively narrow, generally less than 5% of the center wavelength value.
