Explanation:
Detailed explanation-1: -The condenser has an iris diaphragm that controls the angle of the beam of light focused onto the specimen. The iris diaphram is an adjustable shutter which allows you to adjust the amount of light passing through the condenser. The angle determines the Numerical Aperture (NA) of the condenser.
Detailed explanation-2: -Condenser Aperture Diaphragm Operation The opening and closing of this iris diaphragm controls the angle of illuminating rays (and thus the aperture) which pass through the condenser, through the specimen and then into the objective.
