You would adjust the diaphragm in a microscope to control the amount of light passing through the specimen. Opening the diaphragm allows more light to pass through, while closing it reduces the amount of light.
You would adjust the diaphragm of a microscope to control the amount of light entering the lens system. This is particularly useful when trying to enhance contrast or reduce glare in the specimen being viewed.
After switching the microscope from low to high power, you may need to readjust the diaphragm to regulate the amount of light entering the lens. This adjustment helps maintain optimal image brightness and clarity at different magnifications. Start by opening the diaphragm fully and then gradually close it until the image is clear and properly illuminated at high power.
Your light intensity knob which is either on the right, or left of the base of the microscope. When you increase your magnification via the objective, increase your substage iris diaphragm. ie) 10x objective ~ 0.2, 40x ~ 0.4
You would measure the release bearing clearance at various points to ensure proper engagement. The spring diaphragm would be measured at the fingers to gauge its condition and effectiveness in disengaging the clutch.
Microscopes use refraction by bending light as it passes through lenses to focus the image. The bending of light allows the microscope to magnify the image and create a detailed view of small objects that would otherwise be difficult to see. By controlling the amount of refraction, the microscope can adjust the magnification level.

the diaphragm
You would adjust the diaphragm on a microscope to control the amount of light that reaches the specimen, enhancing visibility and contrast. This adjustment is especially important when switching between different magnifications or when observing specimens with varying transparency or color. Additionally, it may be necessary to adjust the diaphragm when using different types of illumination, such as brightfield or phase contrast, to achieve optimal clarity and detail.
The user would have to adjust the diaphragm to let in more or less light for their needs.

Turning the diaphragm will change how much light is let in.

Although the Lab Manual describes it, here it is... Iris Diaphragm: used to regulate the amount of light entering the lens system. Coarse-adjustment knob: used to raise or lower the body tube of the microscope. Fine-adjustment knob: used to bring specimen into sharp focus. Condenser: controls the maximum numerical aperture and to move the condenser itself. Mechanical stage control: used to adjust the slide vertically and/or horizontally to bring slide into central opening of the objective.
Cameras have an iris diaphragm.
A microscope rheostat control is a device that allows the user to adjust the intensity of light on a microscope by regulating the electrical current passing through the light source. This enables the user to increase or decrease the brightness of the light to optimize visibility and contrast when observing specimens under the microscope.
