General/Location
First you must make sure that your microscope is on a stable and solid surface. -
Electric LED lighting with dimmer
Check before use whether the light switch (Fig. 1,21) is set to “off”.
The microscope has two lighting units. Lighting can be of three types. Set the switch (Fig 1, 21) to „II“ to light the specimen from above (reflected light) or „I“ to light it from below (direct light). Use setting „III“ to have the specimen simultaneously subjected to direct and transmitted light. The transmitted light unit (Fig 1, 10) is used for transparent specimens (those on glass slides). To view, solid non-transparent specimens use the direct light unit (Fig 1, 20). Use of both forms of lighting simultaneously is only recommended for semi-transparent specimens. This operating mode is not recommended for direct light specimens on slides as it may cause reflection on the slide.
Use the switch (Fig 1, 21) to select the desired lighting mode and set the dimmer to the desired brightness (Fig. 1, 18).
As your device has continuously controllable lighting (dimmer) optimal illumination of the object to be viewed is guaranteed. -
Colour filter disc
The color filter under the microscope table (Fig. 1, 19) aids in viewing very bright and transparent objects. Just select the right color for the specimen in question. The components of colorless/transparent objects (e.g. starch particles, single-cell -specimens) can thus be better recognized. -
Attach stage
A stage is included along with your microscope (located in the case, under the CD). To install this on the microscope, proceed as follows:
1. Place the stage (Fig. 4, 28) on the microscope stage (Fig. 4, 8) in such a way that the attachment screws (Fig. 4, D) are positioned over the middle threaded hole (Fig. 4, E).
2. Tighten the attachment screws securely. -
Microscope setup
The microscope’s eyepiece (Fig 1, 6) will now be prepared for the first observation.
First, loosen the screw (Fig. 1, X27) and rotate the eyepiece into a convenient position.
Begin every observation with the lowest magnification.
Place the microscope’s table (Fig. 1, 8) with the focus knob (Fig 1, 9) into the lowest position and rotate the objective revolver (Fig. 1, 7) until it locks on the lowest magnification (4x).
NOTE:
First, drive the Microscope’s table (Fig. 1, 8) in its lowest position before changing the objective in order to prevent damages.
Insert the 5x eyepiece (Fig. 3, 1) in the Barlow lens (Fig. 3, 3).
Take care, that the Barlow lens is inserted completely in the monocular head (Fig. 3, 5). -
Observation
After you have set up the microscope with the corresponding illumination, the following principles are important:
Begin each observation with a simple observation at the lowest magnification, so that the center and position of the object to be viewed is in focus.
The higher the magnification the more light is required for good picture quality.
Place a permanent slide culture (Fig. 5, 15) directly under the microscope lens on the plate (Fig. 5, 8) and clamp it on the cross-table (Fig. 5, 28). To do so push the lever (Fig. 5, C) aside.
The specimen to be examined must be directly over the lighting. If not turn the two knurled screws (Fig. 5, A+B) on the mechanical plate.
TIP:
On the mechanical plate (Fig 5, 28) there are two knurled screws (Figs 5, A+B). They are used to precisely position the specimen laterally (Fig 5, A) and vertically (Fig 5, B).
Look through the eyepiece (Fig. 1, 1/2) and turn carefully the focusing wheel (Fig. 1, 9)) until you can see a sharp picture.
Now you can get higher magnification, while you pull out slowly the Barlow lens (Fig. 6, 3) of the monocular barrel (Fig. 6, 5). With nearly entirely pulled out Barlow lens the magnification is raised to 2x.
For still higher magnification you can put the 16x eyepiece (Fig. 2, 2) into the objective revolver (Fig. 1, 7) and set it on a higher position (10x / 40x).
TIP:
Depending on the preparation higher magnifications do not always lead to better pictures.
With changing magnification (eyepiece or objective lens changes, pulling out of the Barlow lens) the sharpness of the image must be newly defined by turning the focusing wheel (Fig. 1, 9).
NOTE:
Please be very careful when doing this. When you move the mechanical plate upwards too fast the objective lens and the slide can touch and become damaged. -
Viewed Object –condition and preparation
7.1. Condition
With the Barlow lens, nearly fully extended magnification can be doubled. Both transparent and non-transparent specimens can be examined with this microscope, which is a direct as well as transmitted light model. If opaque specimens are examined – such as small animals, plant parts, tissue, stone, and so on – the light is reflected from the specimen through the lens and eyepiece, where it is magnified, to the eye (reflected light principle, switch position I). If opaque specimens are examined the light from below goes through the specimen, lens, and eyepiece to the eye and is magnified en route (direct light principle, switch position II). Many small organisms of the water, plant parts, and finest animal components have now from nature this transparent characteristic, other ones must be accordingly prepared. Is it that we make it by means of a pre-treatment or penetration with suitable materials (media) transparent or thus that we cut finest wafers off of them (hand-cut, MicroCut) and these then examine. With these methods will use the following part make familiar.
7.2. Creation of thin preparation cuts
Specimens should be sliced as thin as possible, as stated before. A little wax or paraffin is needed to achieve the best results. A candle can be used for this purpose. The wax is put in a bowl and heated over a flame. The specimen is then dipped several times in the liquid wax. The wax is finally allowed to harden. Use a MicroCut (Fig 2, 24) or knife/scalpel (carefully) to make very thin slices of the object in its wax casing.
DANGER!
Be extremely careful when using the knives/scalpels or the MicroCut. There is an increased risk of injury due to the sharp edges!
These slices are then laid on a glass slide and covered with another.
7.3. Creation of an own preparation
Put the object which shall be observed on a glass slide and give with a pipette (Fig. 8, 22a) a drop of distilled water on the object (Fig. 8).
Set a cover glass (in each well-sorted hobby shop available) perpendicularly at the edge of the water drop, so that the water runs along the cover glass edge (Fig. 8). Lower now the cover glass slowly over the water drop.
TIP:
The gum medium supplied (Fig 2, 25b) is used to make permanent slide cultures. Add it instead of distilled water. The gum medium hardens so that the specimen is permanently affixed to its slide. -
Experiments
If you made yourself familiar with the microscope already, you can accomplish the following experiments and observe the results under your microscope.
8.1. Newspaper print
Objects:
1. A small piece of paper from a newspaper with parts of a picture and some letters 2. A similar piece of paper from an illustrated magazine Use your microscope at the lowest magnification and use the preparation of the daily paper. The letters seen are broken out because the newspaper is printed on raw, inferior paper. Letters of the magazines appear smoother and more complete. The picture of the daily paper consists of many small points, which appear somewhat dirty. The pixels (raster points) of the magazine appear sharply.
8.2. Textile fibers
Objects and accessories:
1. Threads of different textiles: Cotton, linen, wool, silk, Celanese, nylon etc..
2. Two needles
Each thread is put on a glass slide and frayed with the help of the two needles. The threads are dampened and covered with a cover glass. The microscope is adjusted to low magnification. Cotton staples are of vegetable origin and look under the microscope like a flat, turned volume. The fibers are thicker and rounded at the edges than in the center. Cotton staples consist primarily of long, collapsed tubes. Linen fibers are also of vegetable origin; they are round and run in straight lines direction. The fibers shine like silk and exhibit countless swelling at the fiber pipe. Silk is of animal origin and consists of solid fibers of smaller diameters contrary to the hollow vegetable fibers. Each fiber is smooth and even moderate and has the appearance of a small glass rod. Wool fibers are also of animal origin; the surface consists of overlapping cases, which appear broken and wavy. If it is possible, compare wool fibers of different weaving mills. Consider thereby the different appearance of the fibers. Experts can determine from it the country of origin of wool. Celanese is like already the name says, artificially manufactured by a long chemical process. All fibers show hard, dark lines on the smooth, shining surface. The fibers ripple themselves/crinkle after drying in the same condition. Observe the thing in common and differences.
8.3. Saltwater prawns
Accessories:
1. Prawn eggs (Fig 2, 25d)
2. Sea salt (Fig 2, 25c)
3. Prawn breeding plant (Fig 2, 23)
4. Yeast (Fig 2, 25a)
CAREFUL!
Eggs and prawns are not fit for human consumption.
8.3.1 The lifecycle of the saltwater prawn
The saltwater prawn or artemia salina to scientists has an unusual and interesting lifecycle. The female‘s eggs are hatched without any male shrimp having to fertilize them. The resultant baby prawns are all female. Under unusual circumstances such as when a swamp is drained the eggs may produce male prawns. These males fertilize the female‘s eggs, resulting in a specific type of eggs. These are called winter eggs and have a thick shell as protection. They’re pretty rugged and can survive the swamp or lake drying out causing the death of the entire prawn population for up to a decade in a form of hibernation. The eggs hatch once the right ambient conditions are again obtained. The eggs supplied (Fig 2, 25d) are of this type.
8.3.2. Hatching of the saltwater prawn
To hatch the prawn it is essential to first have a saline solution suited to the prawn‘s needs. Fill half a liter of rain- or fresh water in a container. Let it stand for about thirty hours. As water evaporates over time it‘s a good idea to have a second container of such water left standing for thirty-six hours. Once it‘s stood for this length of time pour half of the sea salt supplied into one of the containers (Fig 2, 25c) and stir until it has dissolved. Then pour some of it into the prawn breeding plant (Fig 2, 23). Add a few eggs and close the lid. Put it somewhere with plenty of light but not in the direct sun. The temperature should be approximately 25° C. The prawns will hatch in two or three days at this temperature. Should any water evaporate during this time replace it from the second container.
8.3.3. The saltwater prawn under the microscope
What comes out of the egg is known as a nauplius larva. Use the pipette (Fig 2, 22a) to put some of them on a slide for examination. They will move in the solution using their hair-like limbs. Remove a few days from the container for examination under the microscope. If you do so and save the pictures made with the MicrOcular you will then have a seamless record of the prawn‘s lifecycle. You can remove the upper lid of the prawn bleeding plant and put the whole thing under the microscope. The larvae will mature in six to ten weeks depending on ambient temperature. You will soon have bred an entire generation of saltwater prawns that constantly reproduce.
8.3.4. Feeding your saltwater prawns
To keep them alive saltwater prawns must be fed occasionally. This must be done carefully as overfeeding causes the water to stagnate and poison the prawns. Feeding is best down with dry powdered yeast (Fig 2, 25a). Give them a little every other day. If the water darkens this signifies it is stagnating. If so remove the prawns and put them in a fresh saline solution. -
MicrOcular setup
NOTE:
The MicrOcular only works without the Barlow lens supplied. The magnification setting is changed by using the MicrOcular and must be reset by focussing anew.
Remove the Barlow lens (Fig 6, 3) and eyepiece currently in use from the eyepiece holder (Fig 6, 5) and replace them with the MicrOcular (PC-Ocular) (Fig 7, 4) as in illustration 7 in the holders (Fig 7, 5)
NOTE:
Please do not yet connect MicrOcular and PC. Please go through the items below in sequence. -
Installation and usage of the software
10.1. Installing the software
You find the capturing software for Win 7 /8.1 / 10 on the CD. Double click on the exe file and follow the instructions in the installation manager. It is not necessary to install a specific driver. The camera will be recognized automatically from suitable Windows operating systems.
10.2. Capturing images
Connect the camera with your PC. Start the software „CamLabLite“ and activate the MikrOkularHD in the camera list of the software. Switch on the microscope and place a sample with good contrast on the microscope stage. Look through the eyepiece and use the lowest magnification to focus on the sample. Now insert the camera as described above. Normally only slight re-focusing is needed to see a sharp image of your sample in the software preview. The software preview will always show the full frame of view. Please note: The camera will show a smaller field of view as can be seen in the eyepiece, which is normal. Maybe choose a different magnification on the microscope to adjust the field of view of the camera. You can save images and video by clicking on the button „Snap“ (single image) or „record“ (Video) respectively. The folder to save files and the language settings of the software can be adjusted. Click the button to enter the options menu. Choose the resolution of the camera from the „Live“ dropdown menu. The resolution of the capture will be adjusted accordingly. The brightness of the image will be adjusted automatically. For best results adjust the microscope illumination to maximum brightness. To adjust the exposure time individually, remove the tick mark from „Auto Exposure“ and choose a different exposure time from “Exposure target“.
For a good result, you can adjust further values from the menu „Color Adjustment“. Depending on the exact model of your camera, certain menu points in the software might be inactive if not supported by the camera hardware.
TIP:
To use the MikrOkular long-term we recommend it always be connected to the same USB port. -
Using the MicrOcular
11.1. 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 install the same in the eyepiece supports 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.
Care and maintenance
Separate the device from the power supply before cleaning (remove batteries)!
Only use a dry cloth to clean the exterior of the device.
NOTE:
Do not use any cleaning fluid to avoid damaging the electronics.
Clean the lenses (eyepiece and/or lens) with a soft and lint-free cloth only (e.g. microfibre).
NOTE:
Do not apply excess pressure to the cloth so as to avoid scratching the
lenses.
To remove more stubborn dirt, moisten the cleaning cloth with an eyeglass- cleaning solution and wipe the lenses gently.
Protect the device from dust and moisture! After use – in particular in situations of high humidity – let the device acclimatize for a short period of time so that the residual moisture can dissipate.
