The document describes the parts and functions of a microscope. A microscope is an instrument that magnifies small objects that cannot be seen with the naked eye. There are different types of microscopes including light, electron, biological, and digital microscopes. The optical parts of a microscope include the ocular lens, objective lens, diaphragm, and mirror. The non-optical parts include the microscope body, macrometer, micrometer, arm, object desk, condenser rotator, microscope stand, condenser, and clamp. Each part has a specific function related to magnification, lighting, focusing, and holding the specimen in place for examination.

6. Optical Parts
a. Ocular Lens
Ocular lens is the lens to enlarge the image from the objective lens and make illusory
image that is upright and magnified.
b. Objective Lens
Objective lens is the lens to magnify the image of the body and make a real image
that is reversed and magnified.
c. Diaphragm
It functions to regulate the amount of light to condenser.
d. Mirror
Mirror has a function to reflect light from a light source to the condenser.

7. Non-Optical Parts
a. Microscope Body
To regulate the focus linking the ocular lense to the objective lense.
b. Macrometer (Coarse Rotator)
The macrometer functions to quickly move the microscope body up and down.
c. Micrometer (Fine Rotator)
The micrometer functions to slowly move the microscope body up and down.
d. Arm of Microscope
The arm has a functions as a handgrip while moving the microscope.

8. e. Object Desk
The object desk functions as a place to put on the object to be observed.
f. Condenser Rotator
The condenser rotator functions to move the condenser up and down in order
to obtain optimum light.
g. Microscope Stand
It functions to support and hold the microscope firmly in position.
h. Condenser
It functions to collect the light from the mirror which is used to light the
preparation.
i. Clamp
The clamp functions to hold the preparation glass to be observed to prevent
a slide.
