How do we increase the amount of light that passes through the specimen?

The amount of light that is directed from the bottom of an optical microscope through a specimen can be increased by using a stronger bulb or light source. A potentiometer can be used to dim or increase the strength of the light source.

What happens when the moon passes through the earth's penumbra?
When the moon passes through the earth's penumbra there is a partial eclipse of the moon for those on the side of the earth facing the moon. If it passes through the umbra, the eclipse is total.
What eclipse passes through the earths shadows?
A lunar eclipse occurs when the full moon passes through the Earth's shadow.
What is it called when the moon passes through the earth's penumbra?
Apulse
What happens when the moon passes through the earth's shadow?
its a lunar eclipse
Point that earth axis passes through?
North Pole or South Pole.
What does a diaphargm on a microscope do?
It regulates the amount of light that passes through a specimen.
Why do you cut a very thin slice of specimen to look under light microscope?
The light is reflected upwards, and passes through the specimen. It passes through easier (clearer) if the specimen is not too thick.
What structure on a microscope controls the amount of light that passes through the specimen?
The diaphram Is What Controls How Much Light Is Released.
What structure on the microscope controls how much light passes through the specimen?
the diaphragm
Which structure controls how much light passes through specimen?
stage opening
Which structure's controls how much light passes through the specimen?
stage opening
Which structure controls how much light passes through a specimen?
jyhjjyiujiiiii
What is transmission electron microscopes?
A transmission electron microscope (TEM) is a microscope in which a beam of electrons is transmitted through an ultra-thin specimen, interacting with the specimen as it passes through it.
After light passes through the specimen it enters what next lens system?
objective lens system
Which structure controls how much light passes through the specimen in microscope?
The answer to this microscope question is the stage opening.
What is the iris diaphragm function on a compound light microscope?
the iris diaphragm controls the amount of light that passes through the stage and, consequently, through the specimen. Reducing the iris diaphragm aperture increases contrast for an image focused under high power by reducing the amount of light that both fills the objective lens and deracts around specimen edges. Opening the iris diaphragm under high magnification increases "flare", the appearance of light "washing out" an object. By decreasing the flow of light through the specimen, the iris diaphragm limits light defraction and saturation.
The amount of energy that passes through a given point in a given amount of time is the?
intensity
