1. Eyepiece (Ocular lens) - It is the lens where the final image of the object is viewed. Usually; these lenses have a magnification of either 10X or 15X.
2. Objective lens - There are 3 types of this 10X (Low power objective lens),
40X (High power objective lens), and 100X (Oil immersion objective lens).
Illuminating:
1. Condenser - It is seen below the stage and made up of a system of convex lenses which focus light from illuminating sources and is used to condense light towards the object. Lowering the condenser diminishes illumination whereas raising the condenser increases the illumination.
2. Diaphragm - It is seen immediately below the condenser and operated by small lenses which protrude to one side. Opening and closing of diaphragm controls the light reaching the object.
3. Illuminator - Illuminator is the light source for a microscope
Mechanical:
1. Base - It helps in holding the various parts of microscope. It also contains a light source.
2. Arm - It is used for holding the microscope. And which is connected the eyepiece to the objective lens.
3. Stage - It is a rigid platform on which specimen to be viewed is placed. It has an aperture at the centre to permit light to reach the object from the bottom. The object on the slide can be moved either sideways or forward and backward with the help of the positioning knobs.
4. Adjustment Knobs:
Coarse Adjustment Knob - It is a large-sized knob used to move the body tube up and down for bringing the object into focus.
Fine Adjustment Knob - It is a small-sized knob. It is used for fine and sharp focusing of the object. Exact focusing is done by this knob.
5. Head - The upper part of the microscope that contains the eyepiece tube and prisms. A monocular head has one eyepiece, a binocular has two (one for each eye), a dual head has two but they are not together, and a trinocular head has three, one which is generally used for a camera connection.
