The biological microscope for teaching BS-2030MH10 is designed for 5 persons to view
simultaneously and is provided with achromatic objectives, wide field eyepieces, abbe condenser,
adjustable Lamp housing illumination, demonstrating indicator with i l luminator and also coax i al coarse
and fine adjustment with focus stop. This microscope with his wide field eyepieces gives a nice and
sharp image and is designed in a very modern way. It is specially designed for clinical examination and
teaching demonstration in laboratories, colleges and medical field, it is also an ideal instrument for
bio l o gical bacteriological, pathological and pharmaceutical research.

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 this instrument stable.
2. Illumination system:
In order to make observed specimen have enough brightness and make the resolving power of
the objectives be used fully, this instrument adopt 24v100w lamp housing illumination. It

composed with condenser and iris diaphragm, turning the iris of the condenser and making the
aperture of condenser suitable for the aperture of objective. Demonstrating indicator with
il l uminator of 6V/3W.
3. Stage and shifter:
Stage is installed on stage rack. It can move up and down and is perpendicular to optical
axis .the shifter 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.
Five persons observe in the same time, one of binocular heads can rotate 360
0
, in the field view,
the center of the image is coincident. This is guaranteed by the instrument, so that the operator
do not adjust by themselves. The eyepiece tube is inclined 45
0
,so it observed 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. One is used as tightness adjustment for
coarse focusing knob. The other is used as coarse focusing stopper. When you lower the stage
and raise it again the stage is at the same level. When you do not the location, you can turn the
flange of the stopper and loose it.

Usage:
1. Rotate the objectives in sequence, according to their magnification, into the 4 thread of the
nosepiece. Insert the eyepiece into the inclined eyepiece tube.
2. Put the specimen on the stage. Adjust shifter 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.

Maintenance:
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 to seep it into the inside of the
objectives so as not to dissolve glue. 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.
