Welcome To The World Of Microscopy!
With the Discovery 150x Student Microscope, you can easily witness ordinary objects
transform into the extraordinary! This single power device will show hidden details in
larger objects like insect legs but still allow you to explore the unexpected structures
in tiny subjects like sand and salt. It offers two types of illumination, which lets you
experiment with both natural light and LED light to discover what type works better for
which specimen. With the included lab set, you dive right into the world of microscopy
with a prepared slide or launch your own investigations using the variety of collection
supplies and the experiment guide!
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 in the compartment located
in the base of the microscope, check the LED 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.
How Do I Operate The Illumination?
This microscope is equipped with two types of illumination – a mirror for natural light
and an LED light. The light sources are located under the stage. To use the mirror, flip
the light source so that the mirrored side is facing up toward the stage, and then angle
the mirror toward a light source. The light will reflect up into the specimen. To use the
LED light, flip the light source so that the mirror is facing down. The LED will come on
once it is facing up toward the stage.

How Do I Observe The Specimen?
Flip over the appropriate illumination source. Position the object or specimen in the
middle of the stage under the stage clips, centered over or the light source. Focus the
image by rotating the focus wheel until a clear image appears in the eyepiece.
Place the prepared slide or specimen directly under the objective lens on the
microscope stage. Secure all slides with the stage clips. The specimen should be
located directly over the appropriate illumination source. Look through the eyepiece
and carefully turn the focus wheel until the image appears clear and sharp.
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. Some specimens will need to
be prepared for viewing. You can read more about creating specimens in the enclosed
microscope experiments booklet.
Troubleshooting Table
Problem Solution
No recognizable image • Make sure the light source is
directed at the specimen
• Readjust focus
No image • Center object on slide under
lowest power objective
No light • Replace batteries
• Make sure the mirror is
angled to reflect a light source
• Check on/off position

Cleaning Tips
To ensure your microscope has a long service life, clean the lenses (objective and
eyepiece) with only a soft, lint-free cloth, like a microfiber cloth. Do not press down
too hard while cleaning, as this might scratch the lens. Ask your parents to help if
your microscope is really dirty. To avoid causing damage to electrical components, do
not apply cleaning fluids directly to the device. If necessary, the cleaning cloth can be
moistened with cleaning fluid and the lens wiped clean using very little pressure. Make
sure your microscope is always protected against dust and dirt. After use, leave it in a
warm room to dry off before storing. Batteries should be removed from the device if it
will not be used for a long period of time.
