Glossary, Equations, Parameters
The following is a list of terms commonly used to describe the spectral characteristics of filters. Attentuation Region (or Blocking) The spectral region over which very low transmission is required. Attenuation requirements are generally specified in percent transmission over a given spectral interval. Example: Attenuation for a narrow bandpass filter centered at 2.0 μm may be specified as absolute transmission to be less than or equal to 0.1 percent, from 0.4 to 1.9 μm and from 2.1 to...
