Bandpass filters pass a narrow spectral band of UV, visible, or NIR radiation and reject out-of-band wavelengths from X-ray to the far IR. Applications include spectra radiometry, medical diagnostics, chemical analysis, colorimetry, astronomy, or any application where spectral isolation is required.
