A motorized iris lens is an optical lens with a motorized variable iris. In industry, lenses with a motorized iris are used to compensate for large differences in brightness in the environment. For instance, in traffic situations that change light levels throughout the day, the motorized iris automatically adjusts the exposure to match the scene.
Manual iris control in this situation would result in uneven exposure and poor image quality or is physically impossible.
To achieve the highest precision, Schneider-Kreuznach uses a stepper motor to adjust the aperture.
