6. Coarse Adjustment: 50mm 7. Fine Adjustment: 1.8-2.2mm 8. Stage: 120×100 mm 9. Mirror (plane and concave) 50mm diameter

Operation

1. Place the specimen slide on the stage and clamp it with clips.

2. Mount objectives on revolving nosepiece and eyepiece on body tube respectively.

3. Use low power objective to observe the object first and then move the objective to the center of the bright field of view, then with a high power objective to observe.

4. When focusing, first adjust knob forward until a sharp image is obtained. When using high power objective raise the objective from the lowest position gradually to make it not in contact with the specimen slide to avoid any possible damage.

5. Turn reflecting mirror until the illuminating light reflects into the tube and brightfield of view is visible, then adjust the aperture of iris diaphragm (disc) to secure clear image. Note: DO NOT REFLECT THE SUN WITH THE MIRROR.
   This can cause serious eye injury or permanent eye damage.

6. Observe the specimen using the lowest magnification objective first. The 4x objective provides a larger field of view to search specimen.

7. To clearly see the outline of the specimen, rotate the coarse adjustment knob and lower the barrel to the space limiter.

8. Rotate the fine adjustment knob until the image is in sharp focus. When using other objectives, rotate the fine focus adjustment until the image is in focus.

Diaphragm

1. To obtain the best contrast for observing, match the hole size to the objective that is being used to view the specimen.
2. Each hole has a corresponding number from 1 to 5. 1 is the smallest hole; 5 is the largest hole Use the following guidelines to match the hole number to the objective that you have selected
   • 40x objective: Use #5 hole
   • 10x objective: Use #4 or #3 hole
   • 4x objective Use #2 or #1 hole

Maintenance

Proper care and storage of this instrument is essential. Please read the following guidelines

1. Keep the instrument in a dry and moisture-free location.
2. Do not expose to acid, alkali fumes or moisture.
3. Keep optical parts clean and free of dust. To clean optical parts gently wipe with lens cleaning tissue and a mixture of alcohol and diethyl ether. Depending the weather conditions the following is the recommended mixture rations.
   • Wet weather 1:2
   • Dry weather 1:1
4. After use, cover the instrument with the plastic dust cover.
5. If instrument is to be store for an extended period of time remove the eyepiece and oculars and store in moisture proof container.

2. Attach 4x, 10x and 40x objectives to revolving turret.

3. Place the specimen on the stage and secure with spring clips. NOTE: The cover glass must face upward (the thinner glass is the cover glass), otherwise when the 40x objective is used the specimen cannot be observed.
   Observation is best when the thickness of the cover glass is 0.1-1.1mm and the cover glass is 0.17mm.

4. Plug power cord into an electrical outlet. Turn microscope lamp ON.

5. Observe the specimen using the lowest magnification objective first. The 4x objective provides a larger field of view to search specimen.

Structure

Mounting
Mounting is the base of the microscope. It supports the all weight of the microscope. This mounting has four rubber foots and that makes the instrument stable.

Illumination System
In order to make the observed specimen have enough brightness and make the resolving power of the objectives be used fully, this instrument adopt 6V20W built-in brightness variable lamp. Turn the iris of the condenser and make the aperture of condenser suitable for the aperture of objective. The condenser is composed of two parts. One is installed on trestle. This trestle can move up and down by rack and gear. The light axis of the condenser must coincide with the light axis of this instrument. When they diverge, adjust 3 screws in the trestle of the condenser. The other is installed on the mounting.

Mechanical Stage
The mechanical stage can make the specimen move transversely and longitudinally.

Eyepiece, Objective and Nosepiece
The microscope imaging system is composed of eyepiece and objective.
According to their magnifications, rotate the objectives into the threaded holes of the nosepiece so that when turning the nosepiece, you can change the objectives and get the needed magnification swiftly. The nosepiece adopts precise and advanced structure. When changing the objectives, the center area of the field view always locates within the range of observing and satisfies the focusing requirement. The eyepiece tube that the eyepieces are inserted into is inclined 450 and so observing is comfortable and convenient.

Coarse and Fine Focusing Equipment
This instrument adopts coaxial coarse and fine focusing equipment. The knobs are located below the stage. So it is easy to operate. Coarse and fine focusing
range is 30mm. There is knob beside each coarse focusing knob. Right one is used as tightness adjustment for coarse focusing knob. The other is used as coarse focusing stopper. When you see the specimen clearly, you may lock up the stopper. When you lower the stage and raise it again the stage is at the same level. When you do not need the location, you can turn the flange of the stopper and loose it.

Warning: When using high power objective, move adjustment knob slowly.
Moving the adjustment quickly may cause the objective to break the slide.

Usage

1. Rotate the objectives in sequence, according to their magnification, into the thread holes of the nosepiece. Insert the eyepieces into the inclined eyepiece tube.
2. Put the specimen on the stage. Adjust it and make the specimen in the center of the hole of the stage. Use adjustment knobs located on the left side of the microscope.
3. First use objective 10x, turn the coarse focusing knob and make the objective near specimen and then observe the image through eyepiece and turn the coarse focusing knob down until you can see the specimen image. After that turn the fine focusing knob until you get a sharp image. Because this instrument adopts precise and reliable nosepiece, you can always observe a clear image with different objectives.
4. Take out the lower condenser and put a plan-concave reflecting mirror and you can also observe the specimen image.

Includes

Maintenance

• The microscope is the same as other optical instrument. Need to be kept in cool, dry, dustless and aidless place. The instrument should be covered with dust guard after using.
• Never disassemble the lens because they are corrected stringently. If there is stain on the lens, it can wipe out by alcohol, but you should pay attention not seep it into the inside of objectives so as not dissolve glues. Dust on the lens can be wiped away by clean brush.
• Coarse and fine focusing equipment and nosepiece are precisely constructed and should not be dismantled without authorization.
• When not in use, keep the objectives in the objective box and cover the eyepiece tube with eyepiece tube cover.
