2. MICROSCOPE The word Microscope is derived from the Greek word in which ‘Micro’ means is small and ‘Scope’ means examine or inspect. A Microscope is a valuable instrument and also laboratory instrument used to examine object that are too much small to be seen by the naked eyes.

3. PRINCIPLE OF MICROSCOPE The working principle of Microscope is that the arrangement of lens is such that it magnifies that objects from the complex system. SYNONYMS Eyeglass Lens Hand glass Loupe Hand lens Simple Microscope

4. PARTS OF MICROSCOPE Eye piece • Fine focusing knob Microscope tube • Light source Nose piece Objective Mechanical stage Condenser Coarse

5. TYPES OF MICROSCOPE Simple microscope Compound microscope Electron microscope Stereo microscope Scanning probe microscope

6. OPERATION OF MICROSCOPE Ensure that the microscope and its surrounding area is clean. Plug the microscope and turn on the microscope by rotating illumination control knob on the bottom left side of the instrument. Set the intensity of light. Place the Specimen on the slide. Rotate the nose piece to move object into the working position. Adjust the eye tubes for inter papillary distance and eye difference. Use the aperture diaphragm so that adjusted to enhance contrast. When changing to higher power objectives, the position of the aperture diaphragm must be reset.

7. CLEANING AND MAINTENANCE Clean the lower magnification objective and optical surface with cotton tip moistened with methanol. Avoid excessive use of solvent for cleaning. Cover the Microscope after use. The table should be away from water, inks containing chemicals to prevent damage from spills.

8. USE OF MICROSCOPE Use to magnify small objects. Also used to observe an object at cellular level. Used in medical field. Use in educational field.

9. PRECAUTIONS Always carry the microscope with two hands. Do not touch the glass part of lens with your fingers. Always keep microscope covered when there is no use of it. First focus the microscope in lower power and then change to higher power objective lens.
