How Do I Observe The Specimen?

Sitting in your location with adequate

illumination chosen from the colour filter

wheel, the following basic rules should be

observed. Start with a simple observation at

the lowest magnification. Position the object

or specimen in the middle of the stage under

the stage clips, centreed over the lower light.

Focus the image by rotating the focus knob

until a clear image appears in the eyepiece.

Place the prepared slide directly under the objective on the microscope stage

and secure it with the stage clips. The prepared slide should be located directly

over the lower illumination. Look through the eyepiece and carefully turn the

focus knob until the image appears clear and sharp. Now you can select a

higher magnification by rotating to the 15x/300x objective turret. Higher levels of

magnification can be achieved by turning the objective turret to a higher setting

(300x or 900x). Following this procedure creates a steady increase of magnification

without overpowering the view of the object. The following magnification order

should be used: 100x, 300x then 900x. Each time the magnification changes (due

to the objective change), the image sharpness must be readjusted with the focus

knob. When doing this, be careful because if you move the microscope stage too

quickly, the objective and the slide could come into contact and cause damage to

the slide or microscope.

For transparent objects (e.g. sea salt), light is projected by the lower light traveling

from below the stage, through the objective and eyepiece, and finally into your eye.

This process of light transmission is known as microscopy. Many micro-organisms

found in water, plant components and the smallest animal parts are transparent

in nature. Opaque specimens, on the other hand, will need to be prepared for

viewing. Opaque specimens can be made transparent by a process of treatment

and penetration with the correct materials (media), or by slicing. You can read

more about creating specimens in the enclosed microscope experiments booklet.
