the bright eld method.

They perform well in clinical research and tests; teaching demonstrations; bacterioscopy and cytology in medical and health

establishments, laboratories, universities; and may be used for scientic research in agriculture and microbiology.

Microscope assembly

• Unpack the microscope carefully and place it on a at surface.

• Remove the plastic bags and dustproof cover of the eyepiece head.

• Install the LCD screen and tighten the locking screw.

• Inspect all the items included in the kit and dene their purpose.

• D95L LCD: Connect the power cord to the microscope and plug it in.

• D85L LCD: Open the battery compartment, position the batteries according to the polarity marking on the battery

compartment, reinsert the battery compartment door and turn on the microscope. Connect the microscope to the mains

using the power adapter.

Use

Please refer to the g. 1а (Levenhuk D85L LCD) and g. 1b (Levenhuk D95L LCD).

• Turn on the power and the illumination will turn on. Set the brightness at approximately 70%. Place the specimen on the

stage. Make sure the clips hold the specimen rmly in place.

• D85L LCD: Adjust the height of the stage by rotating the locking screw.

• D95L LCD: Iris diaphragm should be adjusted in accordance with numerical aperture of a lens. The best practice is to

make the iris diaphragm slightly smaller than the aperture of the selected lens. Open or close the iris diaphragm using the

adjustment screws. If the adjustment screw is turned to the right, the iris diaphragm is fully open. Note: the diaphragm is

not intended for adjusting the brightness of the illumination. To adjust the brightness, use the brightness adjustment knob.

• D95L LCD: Slide the lter holder, place the lter in it and then return the holder to its initial position.

• D85L LCD: Rotate the diaphragm disk until the passing light ray is reduced to a comfortable brightness level. If the image is

too dark, select a larger aperture to increase the light ray.

• To change the objective magnication, turn the revolving nosepiece until it clicks.

• Make sure that the lens does not touch the sample when adjusting the focus: rotate the coarse focus knob until the

specimen is about 3.175mm (1/8") away from the lens.

• Turn the ne focusing knob to make the image clear. The ne focusing mechanism allows you to focus on the observed

specimen while using high magnications.

• D95L LCD: When you use an oil immersion objective, the space between the specimen and the lens should be lled with

immersion oil. Raise the condenser to the upper position and put a drop of oil on the lens and on the cover glass of the

specimen. Move the revolving nosepiece back and forth to get rid of air bubbles in the oil. Then, x the objective lens in its

working position. Make sure that oil lls the entire space between the objective lens and the specimen. After use, wipe the

lens dry.

• To adjust the position of the mechanical scale (D95L LCD only), turn the coarse focusing knob in a clockwise direction if you

want to x the position of the mechanical scale, or in a counterclockwise direction if you want to loosen it.

• D95L LCD: To place the specimen in the eld of view, move the stage horizontally back and forth or left and right using the

stage moving knob.

• While looking at the monitor, use the focusing knobs to adjust the sharpness of the image.
