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.
