1.APPLICATIONS:
The biological microscope model A11.1141 can be widely used in medical and sanitary
establishments, laboratories, institutes, network of agricultural research, colleges and
universities for clinical microscope inspections and used as instructional equipment. They
also can be used in research work such as biology, bacteriology, cytology, histology and
pharmaceutical chemistry.

3.STRUCTURE:
1.MOUNTING
Mounting is the base of the microscope. It supports the all weight of the microscope. This
mounting has four rubber foots and that makes the instrument stable.
2.ILLUMINATION SYSTEM:
In order to make the observed specimen have enough brightness and make the resolving
power of the objectives be used fully, this instrument adopt LED built-in brightness variable
lamp.
Turn the iris of the condenser and make the aperture of condenser suitable for the aperture
of objective. The condenser is composed of two parts. One is installed on trestle. This
trestle can move up and down by rack and gear. The light axis of the condenser must
coincide with the light axis of this instrument. When they diverge, adjust 3 crews in the
trestle of the condenser. The other is installed on the mounting.
3.MECHANICAL STRAGE
The mechanical stage can make the specimen move transversely and longitudinally.
4.EYEPIECE, OBJECTIVE AND NOSEPIECE:
The microscope imaging system is composed of eyepiece and objective. According to their
magnifications, rotate the objectives into the threaded holes of the nosepiece so that when
turning the nosepiece, you can change the objectives and get the needed magnification
swiftly. The nosepiece adopts precise and advanced structure. When changing the
objectives, the center area of the field view always locates within the range of observing
and satisfies the focusing requirement. The eyepiece tube that the eyepieces are inserted
into is inclined 450and so observing is comfortable and convenient.
5.COARSE AND FINE FOCUSING EQUIPMENT:
This instrument adopts coaxial coarse and fine focusing equipment. The knobs are located
below the stage. So it is easy to operate. Coarse focusing range is 30mm. Fine focusing
range is 30mm too. There is knob beside each coarse focusing knob. Right one is used as

tightness adjustment for coarse focusing knob. The other is used as coarse focusing
stopper. When you see the specimen clearly, you may lock up the stopper. When you lower
the stage and raise it again the stage is at the same level. When you do not need the
location, you can turn the flange of the stopper and loose it.
4. USAGE:
1. Rotate the objectives in sequence, according to their magnification, into the thread holes
of the nosepiece. Insert the eyepieces into the inclined eyepiece tube.
2.Put the specimen on the stage. Adjust it and make the specimen in the center of the hole
of the stage.
3.First use objective 10X, turn the coarse focusing knob and make the objective near
specimen and then observe the image through eyepiece and turn the coarse focusing knob
down until you can see the specimen image. After that turn the fine focusing knob until you
get a sharp image. Because this instrument adopts precise and reliable nosepiece, you can
always observe a clear image with different objectives.
4.Take out the lower condenser and put a plan-concave reflecting mirror and you can also
observe the specimen image.

6. MAINTENCE:
1.The microscope is the same as other optical instrument. Need to be kept in cool, dry,
dustless and acidless place. The instrument should be covered with dust guard after
using.
2.Never disassemble the lens because they are corrected stringently. If there is stain on the
lens, it can wipe out by alcohol, but you should pay attention not seep it into the inside of
objectives so as not dissolve glues. Dust on the lens can be wiped away by clean brush.
3.Coarse and fine focusing equipment and nosepiece are precisely constructed and should
not be dismantled without authorization.
4.When not in use, keep the objectives in the objective box and cover the eyepiece tube
with eyepiece tube cover.
