• In the eyepiece of the auxiliary microscope, besides the phase ring, the diaphragm ring can be seen.
• Center the image of the condenser annular diaphragm in respect to the objective phase ring using the adjustment screws
and then focus on the objective phase ring.
• Fully align the dark ring with the light one. If necessary, move the condenser upwards to align and center the rings with
each other and get the most contrast image. Use filters to make the image even more contrast.
• Replace the auxiliary microscope with an eyepiece and start researching.
• Note: Each change of a specimen or objective lens requires checking and/or centering of the annular diaphragm regarding
the phase ring.
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 D45T comes with a digital camera (fig. 2a), Levenhuk MED D45T 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.
