General Information

Read the user manual carefully before you start working with a microscope. Levenhuk MED Series biological microscopes are 

safe for health, life and property of the consumer and the environment when properly used, and meets the requirements of 

international standards. These microscopes are designed for observing transparent objects in the transmitted light using the 

bright field 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 scientific research in agriculture and 

microbiology.

Microscope assembly

• 

Unpack the microscope carefully and place it on a flat surface.

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

•  Install the monocular, binocular or trinocular head and tighten the locking screw.

• 

Inspect all the items included in the kit and define their purpose.

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

Use

Please refer to the fig. 1а (monocular model), fig. 1b (binocular model) and fig. 1c (trinocular model).

•  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 firmly in place.

•  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.

• 

Slide the filter holder, place the filter in it and then return the holder to its initial position.

• 

To change the objective magnification, 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.

•  Looking into the eyepiece, slowly turn the coarse focusing knob until you can see the image of the observed specimen. Turn 

the fine focusing knob to make the image clear. The fine focusing mechanism allows you to focus on the observed specimen 

while using high magnifications.

• 

When you use an oil immersion objective, the space between the specimen and the lens should be filled 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, fix the objective lens in its working position. 

Make sure that oil fills the entire space between the objective lens and the specimen. After use, wipe the lens dry.

• 

To place the specimen in the field of view, move the stage horizontally back and forth or left and right using the stage 

moving knob.

• 

Look through the right eyepiece with your right eye and adjust the image sharpness with the coarse and fine focusing knobs. 

Binocular and trinocular models: Then, look through the left eyepiece with your left eye and rotate the diopter adjustment 

ring to equalize the difference between your left and right eyes vision. Remember the setting for future use. Adjust the 

distance between the eyepiece tubes of the binocular head so that the image merges into a single circle. 

•  Trinocular models: you can install the digital camera to the third eyepiece tube.

Fuse replacement

Unplug the microscope from a power source. Open the fuse holder located on the back of the microscope body with a flat head 

screwdriver. Remove the old fuse and install a new one. Only use the appropriate types of fuses. Close the fuse holder.

Digital camera

Levenhuk MED D10T comes with a digital camera (fig. 2a), Levenhuk MED D10T LCD comes with a digital camera with an LCD 

screen (fig. 2b). A digital camera is installed to the third eyepiece tube and enables observing specimens on the screen in 

exquisite detail and true color, taking photos and videos, and saving the images for future reference.
