The Microscope’s Iris Diaphragm: What it Does And How it

The main function of an iris diaphragm of a microscope is to control the amount of light that reaches the specimen. This light comes from the microscope’s light source, and is gathered by the condenser, before being regulated by the diaphragm, then passing through the specimen.

How to use the Condenser Aperture Diaphragm

The opening and closing of this iris diaphragm controls the angle of illuminating wavefronts that bathe the specimen (and thus the aperture size). Condenser height is controlled by a rack and pinion gear system that allows the condenser focus to be adjusted for proper illumination of the specimen.

Focus on the Field Iris Diaphragm Function

Field Iris Diaphragm Function In the optical microscope, light emitted by the source (such as a tungsten-halogen or arc discharge lamp) is passed through a collector lens system in the lamphouse so that the filament or plasma ball can be focused onto the front focal plane of the condenser.

Diaphragm of a Microscope: What is it and how can it be

Aperture Iris Diaphragm. This diaphragm is located closer to the condenser system of a microscope. In fact, the condenser sits right on top of the iris diaphragm. It operates in the same fashion as described above, but it serves a little different purpose then just making the image more or less bright. This diaphragm is mostly used to control

Iris Diaphragm Biology As Poetry

Mar 18, 2016· 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. The pathway of light through a compound microscope is: light source → condenser → iris diaphragm → stage →
