As the air bubble in the oil immersion will make bad affect to the quality of image,
please make sure that there is no air bubble in the oil immersion before use. Please
check the air bubble as following, remove the eyepieces and open the view field
diaphragm and aperture diaphragm entirely then observe the exit pupil which is light
and in nummular shape
5.9.2.3 Remove the air bubble as following
Turn the nosepiece slowly and turn the oil immersion objective once or twice
Turn the lifting knob for condenser slowly and make the condenser a little bit of up and
down
Increase the amount of oil immersion or change the old oil immersion with new one
5.9.3 Operation for oil immersion
Use the oil immersion as little as possible. The oil immersion will be conglutinated to the stage
and condenser and this will have bad effect the performance if there is too much oil immersion.
Please clean the redundant oil on the objective and condenser after finishing the observation
otherwise the image will be affected. Use the aether to clean the oil then use the pure alcohol
(ethanol or carbinol) to make entirely cleaning. Please repeat the clean three or four times.
Notice: Please follow the instruction from manufactures when the aether or pure alcohol is
used. Keep them away from the fire or electronic spark
5.9.4 Attention
5.9.4.1 Keep the bottle for oil immersion sealed as much as possible and check it periodically
5.9.4.2 Never press the bottle overly as it may caused oil gushed out of the bottle
5.9.4.3 Clean the out surface of the bottle from remanent oil
5.10 Adjusting the coarse focusing knob’s tension
The tension of coarse focusing knob is adjustable. Please turn the
tension controlling ring of the coarse focusing knob clockwise then the
tension will be increased. This ring is near the coarse focusing knob.
If you want decrease the tension, please turn the ring withershins. The
stage will fall down automatically if the tension of the ring decreased
too much
5.11 Micrography
The image from microscope could be get by camera, digital camera and CMOS/CCD camera
5.11.1 Installation and operation for CMOS/CCD camera
5.11.1.1 Installation
﹡
It is similar to assemble the eyepiece tube, just tighten the screw to fix it. Connect the
CMOS or CCD camera with the adaptor and insert it in the photo tube. Adjust the image
to be correct then tighten the screw.
﹡
Use the USB cable to connect the CMOS or CCD camera and the computer
.
(Please
read the instruction in the software to see how to use the software)
5.11.1.2 Operation
﹡
Observe through the 10X eyepieces before photography. Do focusing as the above
steps till sharp image of the specimen displayed by the software and do not do any
adjustment to the camera system
﹡
If the image from the software is too bright or dark, please turn the power supply’s
brightness adjusting knob to adjust brightness of the illumination
﹡
Turn the fine focusing knob to make the microscope is exactly on the focusing plane.
Then turn the diopter adjusting ring on the eyepieces to make sure them are on focus
