MICROSCOPE

• HISTORY

• IDENTIFYING THE PARTS OF

MICROSCOPE

• HOW USING MICROSCOPE

HISTORY

• Antonie van leeuwenhoek, Robert Hooke, and matthias schleiden view sciences people that used microscope device in research at 16th century.

• Microscope is an instrument to magnify small size things which cannot be seen by eye directly

HISTORY

• Microscope have one viewing lens said MONOCULER and Microscope have two viewing lens said BINOKULER

• The object that will be seen by microscope is called Preparation. Preparation is made by slashing or without slashing.

IDENTIFYING THE PARTS OF MICROSCOPE

• A microscope consist of an optical parts and non optical parts.

1. Optical Parts of microscopea. Ocular Lens

Ocular lens is the lens near the observer or the place where our eyes can see the image.

b. Objective LensObjective lens is the lens near the object

IDENTIFYING THE PARTS OF MICROSCOPE

c. DiaphragmDiaphragm has a function to

regulate the amount of light to the condenser.

d. Mirror or source of lightfunctions to reflect the light

from a light source.

IDENTIFYING THE PARTS OF MICROSCOPE

2. Non Optical (Mechanical) Parts of microscope

a. Microscope Body

The body microscope is a tube which can be shifted up and down.

b. Macrometer (Coarse Rotator)

The macrometer functions to quickly move the microscope body up and down.

2. Non Optical (Mechanical) Parts of microscope

c. Micrometer (Fine Rotator)

The Micrometer functions to slowly move the microscope body up and down.

d. Arm of Microscope

The arm functions as a handgrip while moving the microscope

2. Non Optical (Mechanical) Parts of microscope

e. Object DeskThe Object desk functions as a place to put on the object (preparation) to be observe.

f. Condenser RotatorThe Condenser rotator functions to move the condenser up and down in order to obtain optimum light.

g. Clamp

The clamp functions to hold the preparation glass to be

observed to prevent a slide

USING A MICROSCOPE

• Procedure to use microscopea. Must be carried with two hands.b. The microscope body must be in upright

position or the preparation desk must be in a flat position.c. Wet preparation must always be covered

with covering glass.d. Keep the microscope lenses clean.e. During working in lab, not allowed remove any of objective lens.
