All parts: 1 Camera shutter 2 Reduce brightness (-) 3 Increase brightness (+) 4 Set light mode / light off 5 Focus Ring 6 Attachment Piece 7 Illuminator (12 LED Lights) 8 Lens 9 USB Cable 10 USB Connector 11 Stand 12 Focusing knob 13 Illuminated table 14 Preparation holders 15 Box with Object holder, glass covers and Adhesive labels General This is a digital refl ected light micro- scope. You hold it in your hand and can place the bottom section (attach- ment piece) on all kinds of things in order to look at them. Observe, for example, leaves, microorganisms, your skin or hair, and much more. It works best when the thing that you’re looking at (also called the “object”) is fl at. You can also view the enlarged pictures on your computer, as well as take and save them there. Installation Insert the product CD into your PC’s DVD/CD drive. The driver installa- tion starts automatically. Plug the hand microscope’s USB connector (10) into your computer’s USB slot. The lighting (7) turns on and your PC detects the hardware, which is then installed. Soon, the “AMCAP” icon appears on the desktop. Now you can use the hand microscope. Live Observation Press the camera shutter (1) for your hand microscope. A (in general blurry) live image is displayed on the monitor. Hold the hand microscope by the casing and place the attachment piece (6) on an object, for example a piece of paper with writing on it. Turn the focus ring (5) to make the live picture sharper (this is called focus- ing). For a fl at object, there are two focus settings with sharp images, which correspond to two different magnifi cations. For low-power mag- nifi cation, the lens (8) is positioned high, away from the object. For high- power magnifi cation, it is positioned lower, closer to the object. You can adjust the magnifi cation from low to high by turning the focus ring clock- wise. To turn it from low magnifi cation to high, turn the focus ring counter- clockwise. You’ll only know when you have the exact measurement value when you’ve achieved a clear picture of an object (e.g., as shown on your computer screen or printed out on a piece of paper). Turn the microscope until you have a picture that is straight and right side up.14 Light Mode Settings: You can select from 4 different light settings with “MODE”:

• white and yellow light

• white, red and yellow light The light can be shut off altogether using the “MODE” key as well. Regu- late the brightness using the “+” and “-“ keys on the device. (Press and hold the keys!) Taking Pictures Using the camera shutter (1), you can take a picture and save it as a BMP fi le.

pears on the screen with a picture.

3. To save the image, click “File” and

“Save”. Making Movies The “AMCAP” program allows you to make movies with the hand micro- scope and save them as AVI fi les.

3. You can prepare to fi lm with “Cap-

ture” and “Start Capture” in the menu.

4. Start fi lming with “OK” in the

“Ready to Capture” window.

5. Under the “Capture” menu, you

can end your fi lming with “Stop Capture”.

6. If you want to record a new fi lm, fol-

low Step 1 and specify a new AVI fi le with a new name. Otherwise, the fi le will overwrite your fi lm.

7. You can watch your fi lm using a

playback program for multimedia fi les. Magnifi cations In the lower magnifi cation, a picture includes about 10,5 mm x 14 mm of the object. The higher magnifi ca- tion includes about 1 mm x 1,4 mm. In this way, the higher magnifi cation is about fi ve times stronger than the lower one. When, for example, you print a picture that is 28 cm wide on a piece of paper, the magnifi cation is about 20x (low) or 200x (high). Deactivation and Storage Close the “AMCAP” window on your PC screen. Now, you can remove the USB connector (10) from your com- puter’s USB port. You can store your hand microscope in the storage case until the next time you want to use it. This will protect it from dust.15

Photomizer SE Software Photomizer SE Software can be downloaded free of charge from: http://www.bresser.de/downloads/ support/software/photomizer.zip Experiments with the Handheld Digital Microscope Experiment No. 1: Black and White Print Objects:

1. a small piece of paper from a news-

paper with a black and white pic- ture and some text,

2. a similar piece of paper from a

magazine. Place both pieces of paper next to each other on a table. Set your micro- scope to the lowest magnifi cation and place it on the pieces of paper, fi rst on the newspaper and then on the magazine. Compare: The letters on the news- paper look frayed and broken, since they are printed on raw, low-quality paper. The letters on the magazine look smoother and more complete. The pictures in the newspaper are made up of many tiny dots, which ap- pear slightly smudgy. The pixels (half- tone dots) of the magazine picture are clearly defi ned. Experiment No. 2: Color Print Objects:

1. a small piece of color printed

2. a similar piece of paper from a

magazine. Place both pieces of paper next to each other on a table. Set your micro- scope to the lowest magnifi cation and place it on the pieces of paper, fi rst on the newspaper and then on the magazine. Compare: The colored pixels of the newspaper often overlap. Sometimes, you’ll even notice two colors in one pixel. In the magazine, the dots ap- pear clear and rich in contrast. Look at the different sizes of the pixels.16 Experiment No. 3: Textile fi bers Objects and accessories:

1. threads from various fabrics (e.g.

Place the different threads on a table and use the needles to fray them a bit. Dampen the threads with a little water. Set your microscope to the lowest magnifi cation and place it on the threads, one at a time. Compare: Cotton fi bers come from a plant, and look like a fl at, twisted ribbon under the microscope. The fi bers are thicker and rounder at the edges than in the middle. Cotton fi bers are basically long, collapsed tubes. Linen fi bers also come from a plant, and they are round and run in one direction. The fi bers shine like silk and exhibit countless bulges on the thread. Silk comes from an ani- mal and is made up of solid fi bers that are small in diameter, in contrast to the hollow plant-based fi bers. Each fi ber is smooth and even and looks like a tiny glass tube. The fi bers of the sheep’s wool also come from an animal. The surface is made of over- lapping sleeves that look broken and wavy. If possible, compare sheep’s wool from different weaving mills. In doing so, take a look at the different appearance of the fi bers. Experts can determine which country the wool came from by doing this. Rayon is a synthetic material that is pro- duced by a long chemical process. All the fi bers have solid, dark lines on the smooth, shiny surface. After dry- ing, the fi bers curl into the same posi- tion. Observe the differences and the similarities. Experiment No. 4: Table Salt Object: normal table salt. Place a sheet of black paper on a desk. Sprinkle a few grains of salt on the paper and place the microscope on top of them. Look at the salt crys- tals using the lowest magnifi cation of your microscope. Observe: The crystals look like tiny dice and all have the same shape. Experiment No. 5: Leaves and Needles Object: 3-4 different leaves or nee- dles from deciduous trees or fi r trees. When you go for a walk in the forest with your parents, you can collect dif- ferent types of leaves and needles. At home, place them next to each other on a white sheet of paper. Place your microscope on top of them and look at the different leaves and nee- dles with the lowest magnifi cation. Observe: The leaves of the decidu- ous trees have different but more or less regular sections that are separat- ed by lines. These are called “cells.” Most often, the underside of the leaf looks different than the top, and the17

color is brighter. The stalk of the leaf runs through the middle. At its thicker end, there is a “lump” with a bulge. That is the part that connected the leaf to the tree, before it fell away. Some leaves also have a stalk upon which multiple leaves grow from oth- er stalks. Fir needles are long, thin and round. Like the leaves of deciduous trees, they have a light bulge on one side, where they grew from the tree. They do not have individual “cells,” how- ever, but look like they grew in one part. However, when you look more closely, you can see that the needle has many sections. These sections come from the step-by-step growth of the needles. In this way, you can look at many more objects, such as small organ- isms (fl ies, spiders, etc.) or other things from your daily life. Simply put everything on a fl at surface (a desk) and place the microscope on top. Or have you already looked at the hair on your head? No? Than run the hand microscope through your hair. It’s quite funny and surprising, what can be hidden in there. You can discover so many things that you did not know before. Just give it a try!18 DANGER pour votre enfant !
