DISCOVERY NANO MICROSCOPES
General use
The Discovery Nano microscope is safe for health, life and property of the consumer and the environment when
properly used, and meets the requirements of international standards. The microscope is designed for observing
transparent and opaque objects in the transmitted and reected light using the bright eld method, for biological
use and school presentations. May be used by kids over 5 years old.
Caution! Children should use the microscope under an adult’s supervision only.
Microscope parts
• Base. It supports the weight of the microscope and houses the illumination source, electronics, and control
mechanisms.
• Eyepiece tube. Combines the eyepiece with the objectives system. Holds the eyepiece, Barlow lens (below the
eyepiece), or a digital camera (in place of eyepiece).
• Eyepiece and objective. Consist of lenses that allow magnifying the image. The total magnication is
calculated by multiplying the eyepiece magnication to the objective magnication.
• Revolving nosepiece. This triple nosepiece with 3 pre-installed objectives allows you to change objectives
smoothly and easily.
• Stage. Sturdy and reliable stage with two specimen holders can be used to move your slides while observing
them. The lower illumination light passes through the opening in the middle of the stage.
• Diaphragm disk. Is located below the stage and has apertures of various diameter to adjust the passing light
rays. Rotate the disk to select the desired aperture.
• Focusing knob. A coarse focusing system allows moving the stage up and down adjusting the sharpness of
the specimen image.
• Upper and lower illumination. Battery powered LED illuminators. The upper illumination is used to observe
opaque objects whereas the lower one allows observing transparent objects. Use both illuminations to study
semi-transparent objects.
Using the microscope
Getting started
• Unpack the microscope and make sure all parts are available.
• Move the stage to the lowermost position using the focusing knob.
• Make sure the batteries are correctly installed in the battery compartment; insert new batteries if required.
• Insert the eyepiece into the eyepiece tube.
• For the digital camera model: you can attach the digital camera to the eyepiece tube instead of the eyepiece.
Focusing
• Place a specimen on the stage and x it with the holders.
• Select the 4x objective rotating the revolving nosepiece.
• Move the specimen to place its thickest part exactly under the objective.
• Rotate the focusing knob to slowly raise the stage until the objective is close to the specimen; keep checking
the distance between the objective and the object to avoid their contact. Caution! The objective should not
touch the specimen, otherwise the objective or/and the specimen might be damaged.
• Look through the installed eyepiece and lower the stage slowly rotating the focusing knob until you see the
specimen image.
• Such adjustment protects the frontal lens from contacting the object when you use objectives of other
magnications; though, slight refocusing might be required.
• If the image is too bright, rotate the diaphragm disk until the passing light ray is reduced to a comfortable
brightness level. If the image is too dark, select a larger aperture to increase the light ray.
Selecting the objective
Start your observations with the lowest magnication objective and select a specimen segment for detailed
research. Then move the specimen to center the selected segment in the eld of view, to make sure it keeps
centered when the objective is changed to a more powerful one. Once the segment is selected, you should center its
image in the microscope’s eld of view as precisely as possible. Otherwise, the desired segment might fail to center
