Parts of Microscope
These tenses, also known as ocular lenses, are typically 10o, and also come in 5% 5X and 20X varieties
Eyepiece lens
_______is what you actually look through to see your specimen. The interocular distance is adjustable so that you can keep both eyes open when looking into the microscope.
Eyepiece lens
Also called a revolving nosepiece or turret, this structure holds the objective lenses. Rotating it allows the objective lens to be switched.
Nosepiece
refers to the main section of the microscope, minus the stand (base) orany illuminators
The body
omponents generally include the eveniece and objective lenses out not the focusing block.
The body
is the arca of the microscope between the tube and the base. To carry a microscope, grip the arm with one hand and place the other hand underneath the base.
The arm
Controls the power to the microscope.
On/off Switch
The lens closest to the object being viewed is known as the objective lens.
Objective lens
has a different magnification, including the scanning tens (4X), low porter lans (10X), mid-power lens (40X), and high-power lens (100x).
Objective lens
Most useful at higher powers, the diaphragm is typically a five hole disc housed under the stage that adjusts the amount of Light passing through the stage opening.
Diaphragm
This area is the main, flat surface that holds the slides for observation.
Stage
Each opening is a different diameter controlling how much light passes through to help property illuminate the specimen while also increasing contrast and resolution.
Diaphragm
The larger of two adjustment knobs that moves the objective lenses closer to, or farther away from, the specimen in large steps (See also Fine Focus)
Coarse focus
are a brand of special paper based cleaning wipes suited for cleaning laboratory equipment and instruments, camera lenses, fiber optic connectors and other sensitive electronic components.
Kimwipes
is the bottom support structure of the microscope, To carry a microscope, grip the arm with one hard and place the other hand underneath the base.
Base
The mechanical stage allows for adjustment of the side position forward, backward, and left or right.
Stage Adjustment Knob
The smaller of two adjustment knobs moves the objective lens close to, farther away from, the specimen in very small steps.
Fine Focus
A special oil is used exclusively with a 100X on high objective lens, typically at 1000X total power.
Immersion Oil
. It can be used to fine-tune the focus on various parts of a specimen after first using the Coarse Focus to get close, (See also Coarse Focus).
Fine Focus
These special paper cleaning materials are specifically designated to be used for cleaning lenses and other glass components without introducing scratches to the surface.

This rectangular plate, made of either plastic or glass is used to bold the specimen. In some cases, it may also contain a depression on well to hold several drops of liquid
