Iris diaphragm

Detailed explanation-1: -The condenser is equipped with an iris diaphragm, a shutter controlled by a lever that is used to regulate the amount of light entering the lens system. Above the stage and attached to the arm of the microscope is the body tube. This structure houses the lens system that magnifies the specimen.
Detailed explanation-2: -In light microscopy the iris diaphragm controls the size of the opening between the specimen and condenser, through which light passes. Closing the iris diaphragm will reduce the amount of illumination of the specimen but increases the amount of contrast.
Detailed explanation-3: -Iris: The iris is the colored part of the eye that surrounds the pupil. It regulates the amount of light that enters the eye. Lens: The lens is a clear part of the eye behind the iris that helps to focus light and images on the retina.
