Aperture Diaphragm

The aperture diaphragm can be narrowed to decrease the amount of light hitting the specimen. This will decrease reflections off the specimen and increase the image contrast. However, closing the aperture too much will cause a loss in detail.

Field Diaphragm

The field diaphragm can be narrowed to decrease the field of view.
