2. MICROSCOPE
•IS A TOOL THAT PRODUCES ENLARGED IMAGES OF
SMALL OBJECTS, ALLOWING THE OBSERVER TO HAVE
AN EXCEEDINGLY CLOSE VIEW OF MINUTE
STRUCTURES IN A SLIDE. IT IS PRIMARILY USED FOR
EXAMINATION AND ANALYSIS

3. •SIMPLE LIGHT MICROSCOPE- MAGNIFYING GLASS
•COMPOUND MICROSCOPE
•THREE TYPES:
•MECHANICAL PARTS- ADJUSTMENTS AND SUPPORT
•MAGNIFYING PARTS- ENLARGE THE SPECIMEN
•ILLUMINATING PARTS- PROVIDE THE LIGHT

4. MECHANICAL PARTS
BASE – BOTTOM MOST
PORTION THAT SUPPORTS THE
ENTIRE/LOWER MICROSCOPE

5. PILLAR – PART ABOVE THE
BASE THAT SUPPORTS THE
OTHER PARTS

6. INCLINATION JOINT – ALLOWS
FOR TILTING OF THE
MICROSCOPE FOR
CONVENIENCE OF THE USER

7. ARM/NECK –
CURVED/SLANTED PART
WHICH IS HELD WHILE
CARRYING THE
MICROSCOPE

8. STAGE – PLATFORM
WHERE OBJECT TO BE
EXAMINED IS PLACED

9. STAGE CLIPS – SECURES
THE SPECIMEN TO THE
STAGE

10. STAGE OPENING

11. BODY TUBE – ATTACHED
TO THE ARM AND BEARS
THE LENSES

12. •DRAW TUBE – CYLINDRICAL
STRUCTURE ON TOP OF THE
BODY TUBE THAT HOLDS THE
OCULAR LENSES.

13.  REVOLVING/ROTATING NOSEPIECE – ROTATING DISC WHERE THE OBJECTIVES ARE ATTACHED.
 DUST SHIELD – LIES ATOP THE NOSEPIECE AND KEEPS DUST FROM SETTLING ON THE OBJECTIVES
 COARSE ADJUSTMENT KNOB – GEARED TO THE BODY TUBE WHICH ELEVATES OR LOWERS WHEN
ROTATED BRINGING THE OBJECT INTO APPROXIMATE FOCUS
 FINE ADJUSTMENT KNOB – A SMALLER KNOB FOR DELICATE FOCUSING BRINGING THE OBJECT INTO
PERFECT FOCUS
 CONDENSER ADJUSTMENT KNOB – ELEVATES AND LOWERS THE CONDENSER TO REGULATE THE
INTENSITY OF LIGHT
 IRIS DIAPHRAGM LEVER – LEVER IN FRONT OF THE CONDENSER AND WHICH IS MOVED HORIZONTALLY
TO OPEN/CLOSE THE DIAPHRAGM
