silver halide emulsion
An emulsion in which grains of the photosensitive material silver halide are deposited. Each grain, when exposed to light, either develops or fails to develop as a unit, leaving a dark or clear region on the developed negative. The size of the grains relates to the sensitivity of the emulsion and the resolution of the image.

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...
