6. Unpacking
The microscope is housed in a moulded Styrofoam container. Remove the tape from the edge of the container
and lift the top half of the container. Take some care to avoid that the optical items (objectives and eyepieces)
fall out and get damaged. Using both hands (one around the arm and one around the base), lift the microscope
from the container and put it on a stable desk.
Do not touch with bare hands optical surfaces such as lenses, lters or glasses. Traces of grease or other
Residuals may deteriorate the nal image quality and corrode the optics surface in a short time.

7.5 Assembling procedure
7.5.1 SLX-1 / SLX-2 / SLX-3
• The microscope is shipped from the factory
with the batteries already installed. However,
in some cases it is necessary to ship the mi-
croscope with the batteries disconnected.
1. Open the lid of the battery compartment. (Fig. 1)
2. Insert the provided rechargeable batteries (re-
specting the polarity of each battery). (Fig. 2)
3. Close the lid.
4. Insert the microscope body in the holder. (Fig. 3)
5. Lock the xing knob ①. (Fig. 4)

6. Remove the eyepieces dust caps and insert the
eyepieces in the empty eyepiece sleeve. (Fig. 5)
7. Connect the jack of the power supply to the sock-
et in the rear part of the microscope base. (Fig. 6)
7.5.2 SLX-4 / SLX-5
1. Screw the pillar on the base. (Fig. 7)
2. Tighten the screw to lock the pillar. (Fig. 8)

3. Insert the drop preventing ring and x it at the de-
sired height by screwing the xing knob. (Fig. 9)
4. Insert the horizontal arm and secure it with the
xing screw ①. (Fig. 10 - 11)
5. Install the head holder. Unscrew the locking knob
③ and insert the arm for the focus support from
above ② into the hole of the horizontal arm. (Fig.

8. Use of the microscope
8.1 Adjust interpupillary distance
Hold the right and left eyepiece tube with both han-
ds and adjust the interpupillary distance by moving
the two parts (Fig. 16) until one circle of light can be
seen. If two circles appear, the interpupillary distance
is too big, and if two overlapped circles appear, the
interpupillary distance is too small.
8.2 Focus
Put the sample to be observed on the stage plate
and focus the sample using the focusing knobs of the
stand ①. (Fig. 17)
8.3 Adjusting the tension of the focus knob
• This adjustment allows to increase or decre-
ase the tension of the knob by avoiding an
involuntary descent of the microscope body
under its own weight. Adjust the tension just
above the point where the focus is stable.
Grab the focus knobs with both hands and, holding
left knob rotate the right one in the direction shown
in Fig. 18 to increase the tension. Tension increases
or decreases according the sense of rotation of the
right focus knob.

8.4 Dioptric compensation
• This compensation makes possible for peo-
ple wearing glasses to adjust the microscope
to their eyes and use the microscope without
glasses.
1. Put the zoom ② down to the lowest magnication
and focus the specimen with the focusing knobs
③. (Fig. 19)
2. Put the zoom to the maximum magnication and
repeat the focusing.
3. Return to the lowest magnication: the specimen
will be out of focus.
4. Adjust the diopter compensation ring of the right
eyepiece ④ until the image of the right eyepiece
is clear and sharp (Fig. 20). Repeat the procedu-
re for the left eyepiece.
5. Then, check the focus of the image for the whole
zoom range. It should now be perfectly parfocal
(focus is always maintained during the change of
magnication).
8.5 Magnification
SLX-1
1. Rotate the magnication changer ⑤ to insert the
desired lens in the optical path. (Fig. 21)
• Rotation in clockwise direction will move from 2X
to 4X lens.
• Counterclockwise rotation will change from 4X to
2X.
SLX-2 / SLX-3
1. Select the desired magnication by adjusting the
zoom knob ⑥.
• Change the eyepieces and/or add an appropriate
additional lens if necessary.
• The microscope body is equipped with a “ma-
gnication lock” function that allows to obtain a
precise setting of the desired magnication. Ma-
gnication lock can be activated or deactivated
by operating with the provided allen wrench in the
hole ⑦ placed in front of the microscope body.

8.6 Use of additional lens
• Additional lenses can be used on models SLX-2 /
SLX-3 / SLX-4 / SLX-5.
1. Screw the desired additional lens on the micro-
scope body. (Fig. 14)
• Each additional lens has a specic Working Di-
stance (see table below).
• (SLX-2 / SLX-3 only): The stroke of the focus
adapter could not compensate the di󰀨erent wor-
king distances of the several additonal lenses.
Fig. 23
Total magnication used can be calculated as:
Eyepiece magnication * Zoom magnication * Objective lens magnication.
Eyepiece 10X 15X 20X
Field number 21 15 10
Objective Total mag. F.O.V. (mm) Total mag. F.O.V. (mm) Total mag. F.O.V. (mm)

8.6.1 Use of 0.5X additional lens (ST-085.1)
0.5X additional lens has a Working Distance of 165
mm and therefore the total stroke of the focus pillar
cannot compensate.
In order to let the 0.5X additional lens working pro-
perly (when used with SLX-2 / SLX-3 models), pro-
ceed as follows:
1. Screw the additional lens on the microscope body
as already described in chapter 8.6.
2. Uninstall the microscope body from the head hol-
der.
3. Install the provided spacer ① in the head holder
and screw the xing knob ②.(Fig. 24)
4. Re-install the microscope body onto the spacer
and screw the xing knob ③.(Fig. 25)
5. Begin working normally.

8.6.2 Use of 1.5X additional lens (ST-086.1)
1.5X additional lens has a Working Distance of 47
mm and, in case of very thin specimens (when wor-
king with SLX-2 / SLX-3 models), the microscope
cannot get a proper focus.
In order to overcome this e󰀨ect, the 1.5X lens is pro-
vided with a transparent spacer ④ that must be pla-
ced on the base plate (Fig. 26).
Once placed the transparent spacer, the user can put
the specimen on the spacer and begin the observa-
tion as usual.
8.7 Use of illumination
1. Turn the transmitted light knob ⑤ in order to turn
ON/OFF or to change the intensity of the transmit-
ted light LED. (Fig. 27)
2. Turn the incident light knob ⑥ in order to turn ON/
OFF or to change the intensity of the incident light
LED.
• It is possible to use both illuminations at the same
time.
8.8 Use with rechargeable batteries
When the power supply is connected to the micro-
scope socket, the “CHG” led ⑦ is lit. (Fig. 28)
RED light: battery with low charge or recharging
GREEN light: battery charged.
• NOTE: when the power supply is disconnected,
the CHG led is always o󰀨.
8.9 Use of eye shields
• Use with eyeglasses
Fold rubber eyeshields with both hands. Folded
eyeshields avoid scratching the lenses of eyeglasses.

• Use without eyeglasses
Raise eye shields and observe at the microscope
placing eyes to the shields, avoiding external light to
disturb the observation. (Fig. 30)
8.10 Use of overhanging stand
Moving the horizontal arm
1. Unlock the knob on the right side of the horizontal
arm ①. (Fig. 31)
2. The arm can be extended or shortened according
to specic needs. (Fig. 32)
Swivel the head
1. Unlock the xing knob ① and rotate the head to
the desired swivel angle (left or right), then tighten
the knob again. (Fig. 33)

Rotating the horizontal arm
1. Loosen the horizontal arm xing knob ② and
rotate the arm, then tighten again the xing knob.
(Fig. 34)
• NOTE: 180° rotation of the microscope with
respect to the base could cause a rollover of
the entire system.

9. Microphotography
9.1 Use of C-mount adapter
1. Loosen the clamping screw ① on the trinocular
port and remove the dust cap ②. (Fig. 35)
2. Screw the C-mount adapter ③to the camera ④
and insert the round dovetail of the C-mount into
the empty hole of the trinocular port (Fig. 36),
then tighten the clamping screw ①.
9.2 Use of Reflex cameras
1. Insert the Reex adapter ① into the relay tube
②.
2. Screw the “T2” ring ③ (not provided) to the reex
adapter.
3. Connect the Reex camera ④ to the “T2” ring just
installed. (Fig. 37)
4. Mount the other end of the relay tube ② into the
empty hole of the trinocular port, then tighten the
clamping screw. (Fig. 35)
• “T2” ring is not provided along with the microsco-
pe, but is commercialy available.
• While shooting dark specimens, darken eyepie-
ces and viewnder with a dark cloth to miminize
the di󰀨used light.
• To calculate the magnication of the camera:
objective magnication * camera magnication *
lens magnication.
• When using an SLR camera, mirror mo-
vement may cause the camera to vibrate.
We suggest lifting the mirror, using long ex-
posure times and a remote cord.
