Your Transmitted-light Microscope

How do I use my microscope?
Before you assemble your microscope, make sure that the table, desk or whatever surface that you want to place it on is stable, and does not wobble.

Electric LED illumination?
The microscope is equipped with modern LED lighting (a light-emitting diode) that illuminates the specimen from below. (By the way, the thing you want to observe with the microscope is known as the object or specimen.)

How do I adjust my microscope correctly?
First, loosen the screw (Fig. 1, 7) and turn the microscope head (Fig. 1, 6) into a comfortable viewing position.
Each observation starts with the lowest magnification.
Adjust the microscope stage (Fig. 1, 11) so that it goes all the way down to the lowest position. Then, turn the objective nosepiece (Fig. 1, 8) until it clicks into place at the lowest magnification (objective 4x).

Note: Before you change the objective setting, always move the microscope stage (Fig. 1, 11) to its lowest position. This way, you can avoid causing any damage!

Now, insert the 10x eyepiece (Fig. 1, 1) into the Barlow lens (Fig. 1, 3). Make sure that the Barlow lens is placed all the way into the eyepiece supports (Fig. 1, 5) and is not pulled out (Fig. 2).

How do I observe the specimen?
After you have assembled the microscope with the adequate illumination and adjusted it correctly, the following basic rules are to be observed:
Start with a simple observation at the lowest magnification. This way, it is easier to position the object in the middle (centering) and make the image sharp (focusing).
The higher the magnification, the more light you will require for a good image quality.

Now place the prepared specimen (Fig. 1, 19) directly under the objective on the microscope stage (Fig. 3). The object should be located directly over the illumination (Fig. 1, 12).

In the next step, take a look through the eyepiece (Fig. 1, 1) and carefully turn the focus knob (Fig. 1, 16) until the image appears clear and sharp.
Now you can select a higher magnification by slowly removing the Barlow lens (Fig. 1, 3) from the eyepiece support (Fig. 1, 5). When the Barlow lens is almost completely pulled out, the magnification can be increased to –almost double. If you would like an even higher level of magnification, insert the 16x eyepiece (Fig. 1, 2) and turn the objective nosepiece (Fig. 1, 8) to a higher setting (10x or 40x).

Important tip: The highest magnification is not always the best for every specimen!
Note: Each time the magnification changes (eyepiece or objective change, pulling out the Barlow lens), the image sharpness must be readjusted with the focus knob (Fig. 1, 16). When doing this, make sure to be careful. If you move the microscope stage too quickly, the objective and the slide could come into contact and become damaged!

For transparent objections (e.g. protozoa), on the other hand, the light shines from below, through the opening in the microscope stage and then through the object.
The light travels further through the objective and eyepiece, where it is also magnified, and finally goes into the eye. This is transmitted-light microscopy.

Many microorganisms in water, many plan components and the smallest animal parts are already transparent in nature. Others have to be prepared. We may make them transparent through a treatment or penetration with the right materials (media), or by taking the thinnest slices from them (using our hand or a specimen slicer), and then examine them. You can read more about this in the following sections.

How do I make thin specimen slices?
Only do this with the supervision of your parents or another adult.
As I already pointed out, the thinnest slices possible are taken from an object. In order to get the best results, we need some wax or paraffin. It is best if you get a candle. Place the wax in a pot and heat it carefully over a low burner. Now, dip the object in the liquid wax a few times. Then, let the wax get hard. Using the specimen slicer (Fig. 1,19) or a knife/scalpel, cut the smallest slices from the object that is covered with wax. These slices are to be laid on a slide and covered with a cover slip.

How do I make my own specimens?
Take the object that you want to observe and place it on a glass slide. Then, add a few drops of distilled water on the object (Fig. 7) using a pipette (Fig. 1, 19). Now, place a cover slip vertically at the edge of the drop of water, so that the water runs along the edge of the cover slip. Then, slowly lower the cover slip over the water drops (Fig. 8).

Note: The included glue “gum media” (Fig. 1, 18) is used to make permanent prepared specimens. Use this in place of the distilled water. If you want to keep the object in place on the slide permanently, use the gum media.

How do I install the MicrOcular?
Note : The MicrOcular only works without the included Barlow lens! The magnification setting is changed when the MicrOcular is used, and it must be readjusted with the focus knob.
First, remove the Barlow lens (Fig. 4, 3) with the current eyepiece from the eyepiece support (Fig. 4) and place the MicrOcular (Fig. 5, 4) in the eyepiece (Fig. 5).

How do I install the software?

1. You can download the setup file for installation here: www.bresser.de/download/CamLabLite_Junior
2. Start the installation with a double click on the .exe file and follow the instructions of the installation manager.
3. It is not necessary to install a special driver. The camera is automatically recognized by your Windows operating system.

Using the MicrOcular

Preparation

1. Slide a specimen under your microscope and focus on it.
2. Remove the eyepiece and Barlow lens from the eyepiece support and the dust cap from your MikrOkular and then install the MikrOku-lar into the eyepiece support instead of the Barlow lens.
3. Start your PC if you haven‘t yet and connect your MikrOkular to the USB port of your computer.
4. Start the „CamLabLite_Junior“ software and activate the camera by clicking on „USB Video Device.
5. Click on „Snapshot“ to take a picture or on „Capture“ to record a video.
6. Click on the floppy disk icon to save the image or capture.

Troubleshooting

• Readjust focus

• Check Windows privacy settings

Image flickers (while observing with MicrOcular)

= Monitor refresh rate not adequate

| • If necessary, increase resolution of graphics card

•  Adjust brightness at the dimmer of the microscope

•  Disable automatic exposure

Make sure your microscope has a long service life.
Clean the lens (objective and eyepiece) only with the cloth supplied or some other soft lint-free cloth (e.g. microfibre). Do not press hard as this might scratch the lens.
Ask your parents to help if your microscope is really very dirty. The cleaning cloth should be moistened with cleaning fluid and the lens wiped clean using little pressure.
Make sure your microscope is always protected against dust and dirt. After use leave it in a warm room to dry off. Then install the dust caps and keep it in the case provided.
