6
Gives the highest magnification with a magnifying power of 97x-100x with a working distance of 1.8mm.
Oil Immersion Objective
7
Found at the top of the microscope which gives the final magnification of the specimen with a magnifying power of 10x.
Ocular or Eyepiece
8
These are found below the stage for light gathering and regulation
Illuminating Parts
9
Has two reflecting surfaces: plane and concave
Mirror
10
Found below the stage connected to the condenser and is used to regulate the amount of light by means of a lever
Iris Diaphragm
11
Found below the stage and is used to concentrate light to the specimen under study
Condenser
12
Consists of precise parts of metals to support and adjust the optical parts
Mechanical parts
13
A heavy U-, V-, or Y-shaped foot that makes the microscope stand stable on any flat surface
Base
14
A short piece of metal supporting the rest of the microscope
Pillar

17
A tubular part attached to the body and bears the upper arm
Body Tube
18
Facilitates the changing of objectives in focus
Revolving or Rotating Nosepiece
19
A concave disc which protects the objectives from dust
Dust Shield
20
A platform with central aperture for the passage of reflected light from the mirror and where the slides to be observed are placed
Stage
21
Replaces the clips and is used in manipulation of the slide
Mechanical Stage
22
Controls and facilitates the movement of the slide forward, backward, or from left to right
Coaxial Stage
23
Regulates the intensity of light given by the microscope
Light Intensity Control Knob
24
Used to raise or lower the stage to get the right image of the specimen
Focusing Mechanism
25
Larger focusing knob for big adjustments
Coarse Focus Knob
