NATIONAL GEOGRAPHIC 300X, 1200X Microscope Set

Product Information: 300X/1200X Microscope Set

The 300X/1200X Microscope Set is a magnification tool that consists of two lenses: the ocular and the objective. The ocular (1) and the objectives in the turret (3) are made up of multiple lenses. The microscope set comes with a micro-projector that can be attached to the ocular (1) to project the image onto a screen. It also has an electronic light source/battery compartment (6) and a mirror (5) for illumination.

Product Usage Instructions

Assembly and Setup

1. Remove all parts from the packaging and ensure that you have all the necessary parts.
2. Place the microscope on a flat and stable surface, such as a table or desk.
3. Attach the ocular (1) to the microscope arm (9).
4. Insert the desired objective into the turret (3) by rotating it until it clicks into place.
5. Place the object to be viewed on stage (4) and adjust the focus knob (2) until the image is clear.

General Usage

• Avoid direct sunlight when using the mirror for illumination as it may cause glare and affect the clarity of the image.
• For electric illumination, remove the protective film from the battery compartment before first use.
• Do not disassemble any parts of the microscope as it may affect its functionality.

Using the Micro-Projector

1. Unscrew the ocular (1) from the microscope arm (9).
2. Attach the micro-projector to the open ocular port, ensuring that the matt screen faces you.
3. Adjust the illumination to brighten the matt screen.
4. The projected image can now be viewed on a screen.

Cleaning and Maintenance

• Use a soft, dry cloth to clean the lenses and other parts of the microscope.
• Avoid using water or cleaning solutions as they may damage the lenses.

Disposal and Warranty

• Dispose of the microscope in accordance with local regulations.
• To benefit from the warranty during the specified warranty period, register your product on the manufacturer’s website.

What is a microscope?

A microscope contains two lens systems: the eyepiece and the objective. We’re presenting these systems as one lens each so that the concept is easier to understand. In reality, however, the eyepiece (1) and the objective in the turret (3) are made up of multiple lenses. The lower lens (objective) produces a magnified image of the prepared specimen placed on the stage (4). The picture, which you can’t see, is magnified once more by the second lens (eyepiece, 1), which you can see as the ‘microscope picture’.

Assembly and location

Before you start, choose an ideal location for using your microscope. It’s important that you choose a spot with enough light for normal observation. Furthermore, it is recommended that you place the microscope on a stable surface because a shaky surface will not lead to satisfactory results.

Normal observation

For normal observation, place the microscope in a bright location (near a window or desk lamp, for example). Remove the microscope from the package and tilt the microscope arm (9) so that it’s in a comfortable viewing position for you.
Turn the focus knob (2) to the upper stop, and set the objective turret (3) to the lowest magnification. Now, take a look through the eyepiece and adjust the mirror (5) so that you see a uniform, bright circle of light. Or, you can use the electronic light source (6). You’ll find further tips about the light source in the next section. Now, place a prepared slide (11) under the clips on the stage (4), directly under the objective. When you take a look through the eyepiece, you can see the magnified specimen. At this point, you still might see a slightly fuzzy picture. Adjust the image sharpness by slowly turning the focus knob (2) until the picture appears sharp and clear. You can now select a higher magnification by turning the objective turret and selecting a different objective.
When you do so, note that the sharpness of the picture must be adjusted again for the higher magnification. Also, the higher the magnification, the more light you will need for good illumination of the picture.
TIP: Avoid positioning the mirror so that it is exposed to direct sunlight since it can cause a glare, which won’t allow you to get a clear picture.

Observation (electronic light source)

NOTE! Before initial operation, the foil used for protecting the battery from discharging must be pulled out of the battery compartment.
Locate the mirror/light on the base of the microscope. Flip the mirror/light with the light facing up and press the button to power on the light. This microscope is equipped with an incandescent light that illuminates the specimen from below.
TIP: The higher the magnification used, the more light is required for a good illumination of the picture. Therefore, always start your experiments with one of the lower magnifications.

Battery change

1. Remove the safety screw from the cover.
2. Remove the battery cover.
3. Slide out the coin battery holder.
4. Install the CR2032 coin battery with the positive (+) polarity facing down and the negative (-) polarity facing up on the holder.
5. Replace the battery cover.
6. Screw in the safety screw back to the cover.

Projector

The included micro-projector (15) is ideal for looking at a specimen with multiple people at the same time. To use the projector, you also have to use the electronic light source (6). This way, you can show your results to your friends and family. Unscrew the eyepiece (1) from the microscope and place the micro-projector on the open eyepiece support so that the matte screen is pointing behind you. Adjust the light so that the matte screen is lit up brightly.
You can adjust the focus of the prepared slide image using the focus knob (2). Make sure to swivel the microscope arm (9) back into an upright position so that you can comfortably observe the specimen. In a dark room, it is also possible to project the microscope picture on a white wall. To do this, remove the matte screen. Swivel the tripod so that the upper edge of the projector is horizontal. Keep in mind that the image brightness is reduced and the picture will be darker if the projector is far away from the wall.
