Aperture Value

The system aperture value meaning depends upon the system aperture type selected. For example, if "Entrance Pupil Diameter" is selected as the system aperture type, the system aperture value is the entrance pupil diameter in lens units. OpticStudio uses the system aperture type and system aperture value together to determine such fundamental quantities as the entrance pupil size, and clear apertures for all components.

Selecting "Float by Stop Size" for a system aperture type is the only exception to this rule. The clear semi-diameter or semi-diameter of the stop surface (set on the Lens Data Editor) is used to define the system aperture if "Float by Stop Size" is selected for a system aperture type.
