Assemble the Microscope Body
Remove the decorative cover (1) of the focus
bracket. Loosen the M4 inner hexagon screw with a
M4 inner hexagon Allen key.
Match the dovetail interface (3) of the microscope
body with the dovetail groove (2) of the focus
bracket group, and insert it from top to bottom in
the direction as shown in the gure.
Tighten the M4 inner hexagon screw on the focus
bracket group with a M4 inner hexagon Allen key.
Replace the decorative cover (1).
Assemble the Objective
Attach the objective (2) into the bottom of the
microscope body (1) by rotating the objective until
objective is fully installed.
Assemble the Focusing Bracket
Loosen the lock knob (1) of the focusing bracket
group. Insert the hole (2) of focusing bracket group
into the column (3), until the focusing bracket group is
in the lowest position. Then tighten the lock knob (1)
to prevent the microscope from turning.
Ensure the focusing bracket is assembled
correctly to prevent the microscope from
tipping over.

Assemble the Microscope Head
Loosen the head set screw (1) fully with a M4 inner
hexagon Allen key.
With the microscope head facing forward, insert the
bottom of the microscope head into the top hole
of the microscope body matching the orientation
groove (2) with the orientation pin (3) of the body.
Secure the microscope head to the microscope body
with the set screw.
Assemble the Eyepieces
Remove the eyepiece tube covers (1).
Insert the eyepieces (3) into the eyepiece
tube until the bottom of the eyepieces
touches the bottom of the eyepiece tube.
Secure the eyepieces with the set screws (2).
Assemble the Stage Plate
Place the stage plate into the well space on
the microscope stand.
To remove the stage plate, press down with
ngertips on one edge of the stage plate.
This will result in the other side of the stage
plate lifting, allowing it to be removed.

position.
Insert one end of the optical ber (1) into
the inner hole (2) of the power supply box
aligning the at surface with the lock screw
(3). Secure the optical ber in place with the
lock screw (3).
Insert the other end of the optical ber (1)
into the hole of the base (4), then secure in
place with the lock screw.
Insert one end of the power adapter (6) into
the inner hole (5) of the power supply box.
Insert one end of the power cable (7) into
the corresponding hole of the power adapter

Before Use:
9Fein
Do no shake or drop the microscope
Do not expose the microscope to direct
sun, high temperatures, dust, or damp
environments. Use a at work surface. Indoor
operating temp 32°- 104°F (0°- 40°C), max
relative humidity of 85%.
When moving the microscope use both hands, holding
by the base and the back of the microscope.
Do not adjust the right and left focusing knob in
opposite directions simultaneously.
After use, cover the microscope with a dust cover and power o the light.
For a clear image, ensure you do not leave ngerprints
on the eyepieces or auxiliary lenses.
Wipe lenses gently with a soft tissue. Wipe o ngerprints from lens surfaces with
lens paper using a small amount of microscope cleaning solution or a 3:7 mixture
of alcohol and ether or dimethyl benzene. (Alcohol and ether are ammable, do
not place these chemicals near re and clean in a ventilated area.)
When cleaning other surfaces of the microscope use water only. A basic detergent
can be used to clean the surface if necessary, but ensure that all the detergent is
removed from the frame with a clean, damp cloth prior to drying the surface.

Set Illumination:
Plug in the LED light source and turn on the
main power switch to “ON”.
Adjust the illumination intensity knob (2)
until the illumination is comfortable for
observation. Rotate the knob clockwise
to increase the brightness and rotate
counterclockwise to reduce the brightness.
Adjust the Reector on BFDF Stand:
The reector has two surfaces, a mirrored surface
and a sandblasted aluminum surface. Both
surfaces are reective with the mirrored surface
being more reective.
Adjusting the reector knob changes which
reective surface is in the light path. The reector
knob moves forward and backward to achieve
dierent lighting eects.

Adjust the Focusing Tension:
If the handle is very heavy when coarse focusing
or the specimen leaves the focus plane soon
after focusing, or the stage declines itself, these
problems can be solved by adjusting the tension
adjustment ring (1).
Rotate the tension adjustment ring (1) according
to the arrow direction in the gure, to tighten the
focusing system; rotate the tension adjustment
ring (1) in the opposite direction to loosen the
focusing system.

Adjust Rheostat / Color Temperature on ILB Stand
The illumination intensity can be controlled by
turning the Rheostat dial.
Adjust the color temperature by inserting the color
temperature control tool and rotating to desired
setting. LCD display will provide a read out of color
temperature and illumination intensity.

Adjusting Diopters:
Turn the zoom knob to maximum
magnication. Adjust both diopter
adjustment rings to zero. Look through
the right eyepiece. If the image is not clear,
turn the focusing knob until it is clear. Turn
the zoom knob to minimum magnication.
Look through the right eyepiece. If the
image is not clear, turn the eyepiece diopter
adjustment until it is clear. Look through the
left eyepiece. If the image is not clear adjust
the left diopter adjustment to get a clear
image.

Adjusting the Interpupillary Distance:
Hold the left and right prism boxes and
rotate them according to the arrowhead
pointed as shown in the gure to the
right. Rotate until viewing is comfortable.
Adjustment rage: 50 - 76mm.
Adjusting the Angel of Observation Head:
Using both hands to move the binocular
components up or down to position the
eyepieces for comfortable viewing.

Right diopter
adjusting ring Engage Detents:
Detents are stop positions at every zoom
magnication value. When the detents
are engaged, there will be a “click” when
the zoom has been positioned in a zoom
magnication. Detents are ideal when the
application requires accurate repeatability.
Insert the Allen wrench into the positioning
screw (1). Rotate the positioning screw
clockwise to engage the detent function.
Rotate the positioning screw counter-
clockwise to disengage the detent function.
* Do not over rotate the positioning screw
as it will damage the hosing and internal
mechanisms of the microscope.

Using the Eye-cups:
The eyepieces feature rubber eye cups that
can be used if desired during observation. To
use the eye cups, roll the edges of the rubber
eye cup up. Fold the edges downward as the
arrows indicate if not in use.
Adjust the Aperture Diaphragm:
Use the aperture diaphragm adjustment
pole to adjust the aperture diaphragm.
Position the adjustment pole to the left
to enlarge the aperture diaphragm and
position the adjustment pole to the right
to decrease the aperture diaphragm.

Selecting the Light Path:
When the beam splitter pole (1) is in the
innermost position, the light is directed to
the binocular head for observation through
the eyepieces. When the beam splitter pole
is in the outermost position, the light is
directed to the trinocular tube which is used
for observation using a camera.
Assembling the C-Mount Adapter:
Loosen the lock screw (1) on the trinocular tube
and remove the dust cap (2). Remove the two
dust caps (3) on the c-mount adapter. Insert the
c-mount adapter into the trinocular tube and
secure in place with the lock screw (1). Connect
the camera to the c-mount adapter. Ensure
the beam splitter pole (4) is in the outermost
position for observation using the trinocular
tube. If the image is not clear, loosen the lock
screw (5) on the c-mount adapter and rotate
the focusing portion of the c-mount (6) until the
image is clear. Once the image is clear, tighten
the lock screw (5).
Assemble and Use the Polarizer Device:
Remove the stage plate (2) from the base
and insert the polarizer (1) onto the base.
Attach the analyzer (3) to the outside
diameter of the main objective (4) and
secure it in place with the lock screw. The
analyzer (5) is adjustable by 360°. Rotate the
analyzer for adjustment.
