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.
Finally, the dimmer control also 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 picture for your eyes.
As a general rule you will find that the higher the magnification you use, the more
light is required and so all light controls will need to be increased.
After using your microscope, turn the dimmer control to the lowest setting and
turn off the power to prolong the life of the halogen bulb.
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.
Please keep the original packing for shipment in case of need for repair or
servicing.
IMPORTANT: Use of Immersion Oil
The only objective requiring oil is the x100 objective. However, once oil is used it
must be wiped off the objective (and possibly the slide) with a lens tissue
otherwise it can ruin the lens. The use of oil also can lead to contamination of the
x40 objective if it is not cleaned off immediately. Unfortunately, it is common for
busy operators to forget to do this.
We strongly recommend that you try to use the x40 or x60 objectives first,
whenever possible, when attempting to examine stained smears (including those
stained for viewing bacteria) before using the x100 objective. You may also wish
to try using the x16 eyepieces as well to increase the magnification without the use
of oil.
