Changing from a large field of view to an increased magnification increases the exposure required … WebGenerally, increasing magnification levels results in a decrease to the brightness gain of the image intensifier. The automatic brightness control algorithms used in analog image intensifiers will compensate by increasing the radiation dose rate by the square of the magnification factor.
