What Is The Function Of The Iris Diaphragm. What does Parfocal mean. If the diameter of the field of view is 56 mm at 40x what would the diameter be at 80x.
Decrease the aperture when viewing. The microscope diaphragm also known as the iris diaphragm controls the amount and shape of the light that travels through the condenser lens and eventually passes through the specimen by expanding and contracting the diaphragm blades that resemble the iris of an eye. The iris diaphragm is a part of the microscope.
A diaphragm is typically found on higher-power microscopes versus less expensive or toy models.
Combined they control both the focus and quantity of light applied to the specimen. The main function of the iris diaphragm is to maximize resolution and image contrast by properly channeling the light rays passing through the specimen. What is the function of the iris diaphragm of the microscope. It is located above the condenser and below the stage.
