What part allows you to adjust the amount of light entering the microscope?
Condenser Diaphragm
Condenser Diaphragm- This diaphragm controls the amount of light entering the lens system. This feature is useful for viewing unstained biological specimens that are translucent. Reducing the amount of light improves contrast, making the specimen “stand out” against the background.
What part of the microscope do you have to adjust to make the image brighter?
Diaphragm or Iris: The diaphragm or iris is located under the stage and is an apparatus that can be adjusted to vary the intensity, and size, of the cone of light that is projected through the slide.
How can you adjust the microscope to have more light?
The microscope rheostat control can be found on the side of the compound microscope body. It will typically be a knob that is turned clockwise in order to increase the light intensity, or counter-clockwise to reduce the light.
What regulates the amount of light in the microscope Why do you need to regulate the light?
The condenser serves two purposes; it regulates the amount of light reaching the specimen and it focuses the light coming from the light source. As the magnification of the objective lens increases, more light is needed. The iris diaphragm (located in the condenser), regulates the amount of light reaching the specimen.

Why regulates the amount of light in a microscope?
Which parts of a microscope are used to regulate the intensity and contrast of light what is the function of each of these parts?
Which parts of a microscope are used to regulate the intensity and contrast of light? the condenser and the iris diaphragm condenser:narrows the beam of light iris diaphragm: is a series of flat metal plates at the base of the condenser to regulate the amount of light passing through the condenser.
Which part of the microscope regulates the light directed at the subject?
The condenser is equipped with an iris diaphragm, a shutter controlled by a lever that is used to regulate the amount of light entering the lens system. Above the stage and attached to the arm of the microscope is the body tube.
