The images you see in your microscope will be upside down and reversed right to left. Your microscope includes prepared slides to help you get started.

1. This microscope uses a mechanical stage

(4) with a stage holder clamp (3) and directional knobs (17). Use the clamp lever to open the clamping arm of the stage holder clamp (3).

2. Carefully place a prepared specimen slide

(3 in x 1 in/76.2 mm x 25.4 mm size) inside the holder and close the clamping arm against the slide.

3. Use the stage movement knobs (17) to

position the specimen over the opening in the stage (4). The large stage movement knob moves the X-axis (forward and backward), while the small stage movement knob moves the Y-axis (side to side). NOTE: To position the specimen directly under the objective lens, close the opening on the iris diaphragm until it is almost completely closed by moving the small lever. You should see a small beam of light projected on to the specimen slide. Now use the stage movement knobs to move the specimen directly inside the beam of light. You are now ready to focus and view the specimen. Use caution to avoid damaging the slide or object. When using higher powers while focusing, make sure the objective lens (2) does not hit the slide or specimen.

1. Start with the lowest power (4x objective

lens and WF 10x eyepieces). Rotate the nosepiece (12) to change the objective lens (2) until the 4x objective lens is directly over the specimen.

2. Rotate each eyepiece diopter (9) clockwise

so that they are all the way down.

3. Adjust the distance between the

eyepieces by sliding the eyepiece in or out horizontally. Grasp the knurled portion of each side of the plate to adjust the plate.

4. While looking through the eyepieces

(1), gradually turn the coaxial focus knob (14) until the specimen comes into view. You may need to adjust the stage movement knobs (17) slightly to center the specimen in the field of view.

5. Adjust the eyepiece side plate until the

whole field of view can be observed through both eyes at the same time without moving your head side to side. Depending on your individual eyes, you may need to make slight adjustments to the right and left eyepieces for the most comfortable viewing. Move the diopter (9) up or down until you have the specimen slide in sharp, comfortable focus.

6. For higher powers, rotate the nosepiece

(12) to change the objective lens (2) to 10x, 40x or 100x. This will yield a greater magnification. Gradually turn the coaxial focus knob (14) to refocus on the specimen. NOTE: To be safe, you should first turn the coaxial focus knob to lower the stage, before turning the objective carriage.

7. You can replace the WF 10x eyepieces

with the WF 20x eyepieces to obtain four additional high power magnifications, including (2000x), the highest power possible. To change the range of working distance of the stage, you need to adjust the limit stop lock. Unlock the limit stop lock by pushing it down. Move stage upward or downward to desired position and then lock the limit stop lock by pushing up. The stage is now locked and will not raise any further from the locked position. Locking the stage also prevents an objective lens from hitting a specimen when viewing.

ADJUSTING THE LIGHTING

Specimens of different sizes, thicknesses, and colors require different levels of illumination. There are three ways to change the amount of illumination when viewing a specimen: adjusting the illumination using the illumination adjustment wheel (18), adjusting the Abbe condenser (5) and adjusting the iris diaphragm (15). ADJUSTING THE ILLUMINATION When viewing a specimen that is not transparent or dark in color you may need to increase the amount of light to resolve certain features or details. To do this, increase the brightness of the illuminator by turning the illuminator adjustment wheel (18) all the way to its highest setting. ADJUSTING THE CONDENSER When viewing with lower power (4x and 10x) objective lenses, you will need to lower the condenser lens in order to spread the light over the larger field of view. To change the position of the condenser (5), rotate the Abbe adjustment knob (6) until the beam of light spreads wide enough to illuminate the entire field of view.

DIAPHRAGM As you lower the condenser (5) to spread out the light or change to a higher power objective lens, your image will appear dimmer. Instead of increasing the light intensity of the illuminator (which may “wash out” fine detail of the specimen you are viewing), open the aperture of the iris diaphragm (15) by moving the lever to let in more light. Opening and closing the diaphragm (15) will give a relief view of the specimen and allow you to change the depth of field of the specimen being viewed. USING FILTERS To bring out different levels of detail, experiment with changing the lighting color. To change colors, open the filter holder on the bottom of the diaphragm (15) by pushing it counterclockwise. Place the color filter in the filter holder and close it. You may need to refocus by adjusting the focus knobs. TRINOCULAR FEATURE Your microscope comes equipped with a trinocular feature. To use the trinocular, follow these simple steps.

1. Unscrew the metal cap on top of the

binocular head (10).

2. Thread the trinocular eyepiece tube onto

head to until fully extended.

4. Insert an eyepiece into trinocular

eyepiece tube. You can now view through the trinocular tube.

CARE, MAINTENANCE, AND

WARRANTY Your Celestron Labs microscope is a precision optical instrument and should be treated with care at all times. Follow these care and maintenance suggestions and your microscope will need very little maintenance throughout its lifetime.

• When you are done using your microscope, remove any specimens left on the stage.

• Turn off the illuminator switches.

• Turn off the LCD monitor — push the on/ off button until you see “Shutting Power Off.”

• Unplug the power cord.

• Always place the plastic bag or dust cover over the microscope when not in use to help keep it clean.

• Store the microscope in a dry and clean place.

• Be very careful if using your microscope in direct sunlight to prevent damage to the microscope or your eyes.

• When moving your microscope, carry it by the “arm” with one hand and not by the focuser knob, LCD monitor, etc. Then, put your other hand under the base for support.

• Clean the outside surfaces (metal and plastic) with a moist cloth.

• Always unplug any cords before cleaning.

• Never clean optical surfaces with cloth or paper towels as they can scratch optical surfaces easily.

• To clean optical surfaces, use an air blower or camel hair brush.

• To clean fingerprints off of optical surfaces, use a lens cleaning agent and lens tissue available at most photo outlets and when cleaning do not rub in circles as this may cause sleeks or scratches to occur.

• Never disassemble or clean internal optical surfaces. This should be done by qualified technicians at the factory or other authorized repair facilities.

• When handling glass specimen slides, use care as the edges can be sharp.
