Iris Diaphragm Lever Microscope : Microscopy 1 - This diaphragm is located closer to the light source of the microscope.. This operates in the same way, but this controls how much light and how large the field of view of the resultant image will be. In a case with unhindered light, we have something like this: There is balance between contrast, brightness and area that you just need to play with and get a feel for. This diaphragm is located closer to the light source of the microscope. The iris diaphragm is named "iris" mainly because it does the same exact thing as the iris does for our eyes.

On the other hand, if you have it almost completely closed, you are preventing a lot of light from getting to the sample. It depends on many factors that could be specific to the specimen, or your microscope. Finally, the light will end up passing through the objective lens (far right) which will magnify the light. This is why focusing microscopes can take such a long time. For example we can use the diaphragm to change how much light will get focused onto the sample.
