Sensitivity class
The sensitivity of the film screen system is determined by the dose required for
attaining an optical density of 1.0 (over fog density and film base). The sensitivity
classes are pre-defined ranges, mostly differentiated by a factor of 2. The higher
the numerical value of the sensitivity class (e.g. 200), the lower the dose required.
