MICROSCOPE

The microscope is an instrument that can magnify or enlarge the image of the object  under it which is too small for the naked eye to see clearly. There are two kinds of  microscopes: the simple and the compound microscope. The simple microscope, like the  magnifying glass, uses a single lens. The compound microscope has two or more lenses  that provide a more powerful magnification.

The parts of the compound microscope (compound light  microscope in some text books) can classified into three  groups: the illuminating, the magnifying, and the  mechanical parts.

Illuminating Parts of the Microscope

Mirror – collects and reflects light through the specimen

Condenser – found underneath the stage and focuses the  reflected light to the specimen

Diaphragm – found at the opening of the condenser and  adjusts the light that passes through the opening of the  stage to the specimen.

Magnifying Parts of the Microscope

Eyepiece – it is where the observer peeps through and  focuses the reflected light to the eye

Objectives – gathers and magnifies the image; often there  are three objectives

  • Low Power Objective (LPO) – shortest of the three objectives that locates and  magnifies the specimen 10x
  • High Power Objective (HPO) – longer tube that magnifies the specimen 40x,  43x, or 45x
  • Oil Immersion Objective (OIO) – may be long or short and enlarges the  specimen 100x.

Mechanical Parts of the Microscope

Adjustment knobs – knobs used in lowering or raising the body tube

  • Coarse adjustment knob – bigger of the two knobs that is used for faster  movement in focusing the LPO
  • Fine adjustment knob – smaller of the two knobs that is used for slower  movement in focusing the HPO.

Arm – supports the base, stage, and body tube and the part held in carrying the  microscope

Base – stable structure that supports the weight of the microscope

Body tube – a cylinder attached to the draw tube where light passes from the object to  the ocular/eyepiece

Draw tube – smaller cylinder attached to the body tube and holds the ocular

Inclination joint – this is a movable hinge that can be tilted to incline the microscope if  needed

Pillar – the post or upper extension from the base to the arm

Revolving nosepiece – holds the objectives and facilitates the circular movement

Stage – the platform with opening at the center where the slide is placed for viewing

Stage clips – keeps the glass slide in place so that it will stay in place and not move.
