Bandpass Filter


The bandpass filter is surrounded by two cutoff bands, which allow only a portion of the spectrum to pass through. It is often used to transmit a portion of the spectrum while cutting off all other wavelengths. Bandpass filters are suitable for a variety of applications, such as spectroscopy, clinical chemistry, or imaging. AOS Optics offers a variety of half-bandwidth bandpass interference filters with a wide range of transmittance and size options.
