How Do I Use My Microscope
Before you use your microscope, make sure that the table, desk or surface that
you place it on is stable and is not subject to vibration. If the microscope needs
to be moved, hold it by the arm and base while carefully transferring it. Once
the microscope is in a suitable location and the batteries are installed, check
the light source to make sure that it illuminates. Use a microfiber cleaning
cloth to gently wipe the lenses off. If the stage is dirty with dust or oil, carefully
clean it off. Make sure that you only raise and lower the stage using the focus
adjustment knob.
How Do I Operate The Illumation?
Locate the mirror/light on the base of the microscope. Flip the mirror/light
to the “on” position (with the light facing up) and the light will illuminate.
This microscope is equipped with an incandescent light that illuminates the
specimen from below. The colour filter wheel is located in the middle of the
microscope stage. The filters help you when you observing very bright or clear
specimens. Using these filters, you can choose various brightness levels and
colours. This helps you better recognize the components of colourless or
transparent objects (e.g. sea salt).
How Do I Adjust My Microscope Correctly?
Place the microscope in a suitable location as described above, and sit in a
comfortable viewing position. Always start each observation with the lowest
magnification. Adjust the distance of the microscope stage so that the stage is
in the lowest position — farthest away from the turret head. Turn the objective
turret until it clicks into place at the lowest magnification (Objective: 5x/
Magnification: 100x). Note: Before you change the objective setting, always
make sure the microscope stage is farthest away from the turret by rotating
the focus knob. Separating the stage and turret by rotating the focus knob will
avoid causing damage to the specimen slide or microscope. When starting an
observation, always start with the 5x objective in the rotating head.

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.
