This series microscope is a high precision instrument designed
and produced by our company. It is specially designed for clinical
examination and teaching demonstration in medical and health
establishments, laboratories, agricultural science and technology
field, research institutes. It is used for routine work and research in
biology, bacteriology cytology and pharmacology. Providing with
some optional accessories, the microscope will be enlarged its
functions in demonstrating, collecting, saving and analyzing of the
miro-image.
B) Principle:
The principle of the microscope is showed in Fig 1. The lamp(a)
illuminates. The light from lamp is introduced to the condenser( b)
and then converged on the specimen (c) by the condenser. The
image of the specimen(c) is first magnified by the objective(d) and
then further magnified by the eyepiece(f). The prism(e) is used to
change the direction of the light.
Total magnification=（magnification of objective）multiply
（magnification of eyepiece）
C) Structure and main specifications:
The structure of microscope is showed in Fig 2.
1. Eyepiece(1):
Usually,the microscope is only equipped with wide-field and
plano-scope eyepiece WF10X. If you need, we will also provide
you wide-field eyepieces as WF5X, WF6X, WF12.5X, WF15X,
WF16X, WF20X, or Huygenian eyepieces as 5X, 6X, 10X, 12.5X,

Fig 1.The Principle Draft
In this microscope, the standard outfit of the objective system is DIN achromatic objectives which are
4X, 10X, 40X (spring loaded), 100X (spring loaded, oil immersion). The objective 100X is a immersion lens.
When the 100X objective is used, between its top and the cover glass, should drop some immersion oil and
be sure to make the air bubble out. If there is some air bubble in oil, you may rotate the nosepiece once
more, or add more oil again. After finish observing, the top of the objective(100X and 40X) and the cover
glass should be cleaned at once. Otherwise the remained dry oil will impair the imaging quality in the next
observing. According to your requirement, we can also provide you infinity system plane-scope achromatic
objectives, infinity system achromatic objectives, plane-scope achromatic objectives, and semi-plan
achromatic objectives.

The stage of this microscope is double
layers mechanical stage showed in Fig 3.
Its size is 125(L)X130(W)mm. Push the rod
of the clamp in the arrow direction showed
in Fig 3, and insert the apecimen into the
clamp carefully. Leave your finger away
from the clamp, the clip will turn back
slowly, and then the specimen will be
holded and moved with the clamp. Rotate
the knob(14) to move the clamp lengthwise
in 30mm. Rotate the knob(15) to move the
clamp crosswise in 60mm. The moving
precision is 0.1mm in both directions.
8. ABBE condenser(26)：
The numerical aperture(N.A.) is 1.25. The screw(9) is used to fix the condenser easily
on the microscope without any tools. The center of the condenser in microscope can be
adjusted by rotating the black-head screws(8) without any tools as following steps: a)turn
the objective 4X or 10X in working; b)turn the plate(10) to make the diaphragm diameter
smaller; c)lower the condenser to make the image of the diaphgram sharp by rotating the
knob(25); d)rotate the screws(8) to concentre the image of the diaphragm with the
eyepiece viewing field. The condenser has been adjusted coaxial with the objective
before the microscope is finished. If not, there will be large different in the veiwing field:
one side may be dark and another side may be bright. Rotate the knob(25), built-in rack
and pinion mechanical system controls the condenser up or down. Usually, raise the
condenser higher when 100X or 40X objective is used; Down the condenser lower when
10X or 4X objective is used. The highest position of the condenser raising up is limitted to
lower 0.2mm below the stage surface before the microscope is finished. When it is
necessary to readjust, do as following steps: a)loose the nut on the screw(12); b)put a
slide on the stage; c)raise the condenser up to 0.2mm about lower below the slide;
d)rotate the screw(12) to touch the bottom of the stage; e)fix the screw(12) with the nut.
Fig 3. Mechanical Stage
9. Focusing system:
It is a coaxial coarse and fine focusing system with rack and pinion mechanism. Its
focusing range is 20mm, and its precision of fine focusing is 0.01mm. Rotate the coarse
focusing knob(24) to raise the stage up or down quickly. Rotate the fine focusing knob(23)
to raise the stage up or down slowly.
Turn the diaphragm plate(10) to adjust the diameter of the iris diaphragm from ? 2 to
? 30mm to match with the numerical aperture of objective in using. When the diameter of
the iris diaphragm is 70-80% of the objective's numerical aperture, the image observed is
sharp in contrast. Look into the tube without eyepiece, you can see the image of the iris
diaphgram.
The filter holder(11) can be turned out to insert the filter when you need. The color of
the filter may be blue, or green, or yellow.
10. Illumination system:
Usually, the illuminator of this series microscope is 6V/20W halogen lamp.(It also may
be 20W incandescent lamp, or 5W fluorescent, or 3.5V/1W LED lamp). Turn the plate
(18) to adjust the brightness. So the image backdrop will be not too bright under the
lower-powered objectives, or too weak under the higher-powered objectives. LED lamp

is soft in light to suit the operator for a long time micro-observation. When the current and
voltage don't overstep their limits, its average life can reach to 100000 hours. It is very
securely because the bulb's temperature is lower than 30°C even in a long time using.
Equiped with rechargeable and high-capacity NiMH batteries, it can avoid the trouble of
power supply shortage.
The position of the bulb in microscope is very import to the imaging quility. When the
lighting centre is not coaxial with the objective, there will be large different in the eyepiece
veiwing field: one side may be dark and another side may be bright. The bulb has been
placed correctly in our factory. When change the bulb, please keep it centring.
Caution:
----Before change a bulb, ensure that the microscope has been disconnected with
the power source.
----The new bulb must be the same specifications as the old one.
----When the illuminator is halogen lamp or incandescent lamp, the base near the
lighting source may be very hot. Don't worry about it, but it must be treated
carefully. Please take the combustible material(such as gasoline, paper, plastic and
cloth) far away from the microscope.
----When change incandescent bulb or halogen bulb, wait until it is cool enough,
otherwise the hot bulb will burn your fingers.
----Don't leave any dust and fingerprints on the bulb, otherwise it may affect its life
and illuminating efficiency.
Lay the microscope on its side, Loose the screw(16) under the bottom, open the bulb
case(19) to change the bulb.
D) How to use and assemble:
1. Unpack the microscope and its parts carefully. Check and sort out all parts according
to the packing list;
2. For the convenience of packaging and delivering, the components and parts may be
separated from the mainframe. Before using, please assemble them together according to
the structure draft(Fig 2).
1) Install the viewing head:
The viewing head of model XSP21-01M, or XSP21-01S, or XSP21-01V is fixed on the
mainframe. But the binocular head of model XSP21-01B and the trinocular head of model
XSP21-01T are usually separated from the mainframes. Loose the screw(27) and take off
the plastic plate cover on the body(22). Take the plastic plate cover on the viewing head.
Finally install the viewing head on the body(22) and fix it with the screw(27). Don't try to
loose another two screws for centring the viewing head on the body(22).
2) Install the objectives(4):
Usually, the objectives are fixed stably on the nosepiece by us. Sometimes, they are
separated from the mainframe. Screw the plastic dust cover out off the nospiece(1) and
take the objectives out off their plastic bottles. Screw them on the nospiece(1) by their
maganification order from low to high.
3)Install the eyepiece(3):
Take off the plastic dust cover from the eyepiece tube and insert the eyepiece needed.
3. The operating steps:
1) Select a position to work where little direct light falls on the instrument. Keep the
microscope far away from a large window and not to face the window, because the direct
light may adversely affect the contrast and resolution of the image.
The following working surroundings are required:
a) Room temperature: 0°C-40°C The highest relative humidity: 85%
b) High temperature and humidity can cause mildew and damage the instrument.

www.optoecu.com 10 / 15 [e-mail]
c) Keep the microscope away from dust. When it is not used, please put the dust cover
over it.
d) Keep the microscope away from vibration.
2) Insert the micro-slide specimen into the clamp(5). Be sure that the cover glass is
facing towards the objective. Otherwise you will not be able to focus your specimen at
using higher powered objective(40X, or 100X).
3) Place a lower powered objective(4X, or 10X) into position and simply turn on the
illuminator.
Caution:
The power supply voltage must be fitted to the microscope; Otherwise it will
damage the circuit and bulb, even lead to insecurity.
4) Rotate the knobs(14,15) to move the specimen so that it is centred over the in-stage
condenser.
5) Focus the objective on the specimen by turning the coarse focusing knob(24) until the
image of your specimen is bright and clear. You can find the focal plane and focusing
upwards by using the lower powered objective, and then you can bring the specimen into
sharp focus by turning the fine focusing knob(23).
6) The specimen now is in sharp focus. Rotate the nosepiece(1) to the other objectives
and focus using only the fine focusing knob(23). Since the optics on the microscopes are
Par-focal and Par-centered, only slightly turn the fine focusing knob(23) to make the image
bright and clear.
Note:
It is important to note that the 4X and 10X objectives can never come into
contacting with your micro-slide specimen because of our built-in stop. The 40X
and 100X objectives may occasionally touch the micro-slide specimen. But because
they have retractable mounts, the micro-slide specimen will not be damaged.
7) To make the image clearer, you can adjust diameters of the iris diaphragm to match
with the numerical aperture of objective in use(Sction 8. ABBE condenser in P.5).
E) Trouble Shooting:

a photography eyepiece 4X as the customer's requirement). Join the camera with the
mount and fix it stably.
4) Push the rod of trinocular head in completely and adjust the microscope in the best
working state according to the manual. Then pull the rod out completely. A micro-image
will appear in the camera previewing window. Focus slightly by the fine focusing knob
and adjust the position of the condenser and the diameter of the iris diphragm to make
the image clearer.
5) Take a picture.
I) Microscope with electron eyepiece:
When the electron eyepiece is used, you can choose model XSP21-01V, or
XSP21-01S, or XSP21-01T microscope. So you can observe by using common eyepiece
at the same time of showing the micro-image in the PC screen. The electron eyepiece is
also used in model XSP21-01M or XSP21-01B microscope.
See Fig 6., and connect the camera with the microscope as following steps:
1) Prepare a PC required:
Hardware:USB2.0 Connecting Socket; CPU: Intel P4; EMS Memory: 256M
Hard Disk: 512M; PC Screen Resolution: 1024*768
Software: win2000(with Mend sp4); or winxp (with Mend sp2) and directx 9.0;
2) Insert the driver CD into your PC and run the installing program as the promating
information (See Appendix B: Digital Camera Head);
3) Prepare the microscope for using. Inser the electron eyepiece into the microscope
tube, and connect it correctly with your PC;
4) Adjust the microscope in the best working state according to the manual and find a
clear image in the eyepiece viewing field. (When a trinocular wiewing head is used, first
push the rod of the head in completely and adjust the microscope in the best working
state. Then pull the rod out completely.) Wait a moment, the micro-picture will be
showed in the PC screen. Focus slightly by the fine focusing knob and adjust the position

of the condenser and the diameter of the iris diphragm to make the picture clearer.
User-friendly sophisticated micro-image process software help you to preview, measure,
compare, count, save and delete. (See Appendix B: Digital Camera Head )
J) XSP21-01DN ditigal microscope:
1) Prepare a PC required:
Hardware:USB2.0 Connecting Socket; CPU: Intel P4; EMS Memory: 256M
Hard Disk: 512M; PC Screen Resolution: 1024*768
Software: win2000(with Mend sp4); or winxp (with Mend sp2) and directx 9.0;
2) Insert the driver CD into your PC and run the installing program as the promating
information (See Appendix B: Digital Camera Head);
3) Prepare the microscope for using. Connect it correctly with your PC;
4) Push the rod of the viewing head in completely and adjust the microscope in the best
working state. Then pull the rod out completely. Wait a moment, the micro-picture will be
showed in the PC screen.
Generally, when low-powered objective(4X, or 10X) is used, the picture in the PC
screen will be too bright to observe after the rode of the viewing head is pulled out. You
can adjust the microscopeto get a satisfied picture in the PC screen as the following ways:
1) Turn the plate(19) to make the illuminator darker;
2) Turn the plate(10) to make the diameter of the iris diaphragm smaller;
3) Rotate the knob(23) to lower the ABBE condenser.
When high-powered objective(40X, or 100X) is used, adjust the microscope to get a
satisfied picture as the opposite way:
1) Turn the plate(19) to make the illuminator brighter;
2) Turn the plate(10) to make the diameter of the iris diaphragm larger;
3) Rotate the knob(23) to lift the ABBE condenser higher.
Finally, focus slightly by the fine focusing knob to make the picture clearer. User-friendly
sophisticated micro-image process software help you to preview, measure, compare,
count, save and delete. (See Appendix B: Digital Camera Head )
