GENERAL HISTOLOGY

Detailed explanation-1: -Iris Diaphragm controls the amount of light reaching the specimen. It is located above the condenser and below the stage.

Detailed explanation-2: -Condenser Diaphragm-the lens system beneath the microscope stage, positioned to concentrate light correctly on the specimen and direct the light rays into the objective.

Detailed explanation-3: -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.

Detailed explanation-4: -The iris diaphragm is a shutter within the condenser that can be controlled by a lever to adjust the amount of light passing through the condenser. The lever can be moved to close the diaphragm and improve contrast. If your field of view is too dark, you can open the diaphragm to let in more light.

Detailed explanation-5: -Iris or diaphragm is the rotating disc found under the stage. Its main role is to control the amount of light passing through the specimen. It is located below the microscope stage and above the condenser lens. An Abbe condenser with an iris diaphragm is often found in most high-quality microscopes.
