Bandpass filters isolate a band of wavelengths from the total spectrum by providing a band of high transmission and bands of high rejection of spectral energy on both the long and short wavelength sides of the transmission band. These optical filters are defined by cut-on and cut-off slopes establishing the transition between high rejection and high transmission. Bandpass filters can be manufactured with a wide variety of performance attributes ranging from the simplest single-cavity, unblocked Fabry-Perot construction, to the more complex multi-cavity, fully-blocked, all-dielectric, single-substrate construction. Bandpass filters are widely deployed in many diverse applications including paint-color formulation, blood chemistry analysis, and traffic control.
