the pupils Iris diaphragm-controls the amount of lightreaching the condenser. The size of the iris diaphragm opening should approx- imate that of the face of the objective lens. Thus, as a general rule, the diaphragm is completely closed when liquid preparations are observed with the low-power objective, and wide open when stained preparations are observed with the oil-immersion lens using natural light. http://74.125.47.132/search?q=cache:MjyDOLz_L4AJ:www.tpub.com/content/medical/10669-c/css/10669-c_228.htm+3.+What+controls+the+amount+of+light+reaching+the+ocular+lens%3F&hl=en&ct=clnk&cd=2&gl=us
Diaphragm...Generally a five hole disc placed under the stage on a high power microscope. Each hole is of a different diameter. By turning it, you can vary the amount of light passing through the stage opening. This will help to properly illuminate the specimen and increase contrast and resolution. The diaphragm is most useful at the higher powers.
The iris diaphragm controls the amount of light entering the ocular lens. The iris diaphragm is located at the bottom of the stage above the light.
A diaphragm regulates the amount of light entering the microscope. Stage opening allows light to pass through the stage of the microscope.
I believe that it is the diaphragm!

the iris controls the amount of light by limiting the volume of light admitted through the iris.
The Lens. The Iris controls the amount of Light reaching the Retina.
It controls the amount of light that reaches the film.
it controls the amount of light let into the slide.
The pupil is a hole that allows light into the eye.
the iris controls the amount of light by limiting the volume of light admitted through the iris.
The colored, and muscular ring around the pupil in your eye. It narrows in bright light and widens when light is dim.It also controls the amount of light reaching the retina
The Shutter and the Aperture are the two controls the Shutter is used to control how long the Film is exposed for and Aperture is used to control how much light is let in
Iris controls the amount of light entering into the eye.
the diaphragm controls the amount of light entering the microscope
The pupil controls the amount of light that enters the eye.
The Lens. The Iris controls the amount of Light reaching the Retina.
There are several factors that control the amount of UV light that enters the atmosphere. The main factors include the ozone layer and weather conditions.
The condenser and iris diaphragm.
SHUTTER in Camera controls the amount and time of light that the Sensor will exposed to.
The amount of UV light reaching the earth varies in a predictable manner. This is determined by the various reactions that take place in the ozone.
How many amount of light are reaching in the film.
