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

∙ 13y agoDiaphragm...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.

What is the function of a diaphragm in a camera?
It controls the amount of light that reaches the film.
What is the function of the diafragm in a microscope?
it controls the amount of light let into the slide.
What lets light into the eye?

What controls the amount of light reaching the retina?
the iris controls the amount of light by limiting the volume of light admitted through the iris.
What is 'irie'?
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
What two parts of a camera controls the amount of light reaching the film?
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

What controls the amount of uv light that enters the atmosphere?
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.
Two parts of the microscope that regulate the amount of light visible through the ocular are the?
The condenser and iris diaphragm.
What lens function controls the amount of light that will exit the lens and expose the sensor?
SHUTTER in Camera controls the amount and time of light that the Sensor will exposed to.
Does the amount of UV light reaching the earth vary in a predictable manner?
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.
Shutter speed can be used to?
