The next step is to adjust the field diaphragm, which is the iris diaphragm closest to the front of the microscope as illustrated in Figure 4. Unplug your microscope and wrap the cord around the base of the microscope, underneath the stage and condenser and around the field iris diaphragm. Usually, lenses such as those found on cameras have the iris diaphragm built in the objective lens. In a microscope objective the iris diaphragm would have to

Diaphragm or Iris: Many microscopes have a rotating disk under the stage. This diaphragm has different sized holes and is used to vary the intensity view in the microscope. One is to reduce the amount of light with the iris diaphragm. Name another way. I'll say by using the rheostat (reduce the amount of light with iris diaphragm: Look for a lever just under the stage near the front. Always replace the cover on the microscope when you put it away

Answer This iris diaphragm of a microscope contains the amount of light that can enter through to the specimen. If the condenser iris diaphragm is open, the image c.Turn on the microscope's light source. d. Place the condenser at its highest position and close the iris diaphragm somewhat to prevent overbrightness. Light from the illumination source of the microscope passes through the diaphragm and is focused closer to or further from the stage, and another, the iris diaphragm
