Regulating brightness of the view: There are several ways to adjust the amount of light
which is shed on a specimen, and the light will affect the observation. In most cases, a
better view is obtained by the use of a colored glass filter inserted below the iris
diaphragm. Slide the filter holder to the right to reveal an open ring. Insert the blue
filter into this ring and slide the filter holder back into position under the diaphragm.
The iris diaphragm below the stage can be opened (slide lever back to left) or closed
(slide lever forward) to control the amount of light directed through the condenser. The
condenser assembly under the stage can be shifted up or down by means of the control
knob (left hand side under stage) to effectively move the light beam closer to (up) or
away from (down) the specimen under observation. MRP-5000 is also equipped with a
field diaphragm installed over the collector lens for Kohler illumination. Open or close
this diaphragm as desired by rotating the outer ring to control the amount of light aimed
at the condenser assembly.
Finally, the dimmer control allows the user to adjust the intensity of the halogen light.
Vary these different methods of regulating the light beam on the specimen to obtain the
most effective view for your microscope needs.
After using your Vision microscope, turn the dimmer control to the lowest setting and
turn off the power to prolong the life of the halogen bulb. Lower the stage by rotating
the coarse adjustment knob. The instrument should be covered with a hood to keep dust
off it or dis-assembled and stored in its styrofoam case.
MAINTENANCE
Like other optical instruments, this microscope should be kept in a cool, shady and dry
place, free from dust, fumes and moisture. If not stored in its box, cover with a hood to
protect from dust.
If there is any dirt settled on the lens, wipe it off gently with some lens paper. If alcohol
is used, be careful not to let it penetrate through the lenses and dissolve the gumming.
Any dust settled on the lenses can be blown away with an air blower or wiped off with a
clean soft camel hair brush. In cleaning mechanical parts and applying non-corrosive
lubricant, take special care not to touch the optical elements, especially the objective
lenses.

APPLICATION
Vision Model MRP-5000 Microscope is one of the most modern designed instruments
for clinical examination and teaching demonstrations in laboratories, colleges and
medical fields. It is also an ideal instrument for biological, bacteriological, pathological
and pharmaceutical research.
These microscopes are equipped with achromatic
objectives, planoscope eyepieces, Abbe condenser, built-in variable light source
providing Kohler illumination and coarse and fine focus adjustment to give a nice sharp
image. The magnifying powers range from 40X to 1000X.
The binocular microscope offers the advantage of being able to observe the specimen
with both eyes at the same time, allowing more comfort for the user when compared to a
monocular microscope. The depth of field of the binocular microscope is longer and a
stereo image can be obtained when observing a specimen.
ASSEMBLY INSTRUCTIONS
1. Remove microscope stand from box and styrofoam packing and place it on a stable
work table.
2. Remove all plastic bags and covering (these can be discarded).
3. Remove binocular head from the packing.
4. Remove the plastic cap covering the neck of the microscope base. Fit the binocular
head into the neck of the microscope stand and tighten with the screw clamp as
necessary. The head is 360° rotatable and can be adjusted to any position desired.
5. Remove the plastic eyepiece tube covers and insert eyepieces into each eyepiece
tube.
6. Attach power cord to the back of microscope and connect to power source.
Your Vision microscope is now ready for use.
