1. FEATURES OF THE TOPCON PHOTO SLIT LAMP,
MODEL SL-6E
1) The convenient, one position control lever allows the base to be guided freely
in fine cross-slide adjustment and vertical movement.
2) The convergent binocular tubes allows easy and natural stereoscopic observation.
3) Camera can be attached without cluttering microscope area and without hamper-
ing slit lamp operations.
4) Unit construction photographic system and observation tube makes attachments
and exchanges very simple.
5) Stereophotographs can be taken very easily, with one shot, by simply exchanging
the normal photographic attachment.
6) Five magnification changes for observation and photography, with higher magni-
fication also possible by interchanging eyepieces.
7) Photographs are possible, with simple auto-winding operations, by simply depres-
sing the release button on the joystick control lever.
8) Background illumination can be added to the slit lamp photograph, as well as
adjusted in brightness.
9) A beam splitter unit is inserted between objective and the prism housings, with
the observation tube fixed to either of the two beam splitter mounts on the unit.
As in the case of the photographic unit, the optical path is partially diverted only
when the observer uses a lever for this purpose.
10) Goldmann Applanation Tonometers T900 and R900 can also be used.

2) Assembling and Instalation
(1) Checking the plug and the voltage
Before actually assembling the instrument, first check the primary voltage of the
instrument and the electric plug connected to the power cord. Next, check the
voltage set with the voltage selector@d.
(2) Installation of the Instrument
The Slit Lamp can be used on top of the TOPCON Adjustable Instrument Table,
or on the lower instrument arm of the TOPCON Ophthalmic Stand, as well as
being used on other similiar equipment.
As noted, however, Model SL-6E is available with two types of table or an
exclusive table@) for use on the adjustable instrument table, which is larger and
has a power unit and an accessory drawer, and an exclusive table for use on
the ophthalmic stand, which is smaller, has a power unit only and also a pro-
trusion or short pole for fitting the socket on the lower instrument arm.
a) Attachment on the TOPCON Adjustable
Instrument Table .
Mount the table of the instrument on
the adjustable instrument table using
four mounting bolts M8 X 20mm with
spring washers. Slightly raise the
AIT-5B whose vertical movement is
set to the lower limit to be deterrent
to bolt insertion.
Note: Check the input voltage and
— fuses before moving the adjustable
instrument table. Fig. 12
Allow the side of the power supply i
panel of & and the vertical operating
side of the adjustable instrument table
to face in the same direction, have
the mounting holes aligned, place ©
on the adjustable instrument table,
then tighten the bolts with a spanner.
b
Attachment on the Ophthalmic Stand
Remove the tape which holds the
plastic washer on the shaft under the
stand.
With the plastic washer attached, insert
the shaft into the hole of the
ophthalmic stand arm.
Note: When using the table, ine oph-
thalmic stand is provided with a power
supply to render the unit right-handed
for the inspector. If the ophthalmic stand
is installed left-handed, it may cause the
power supply to come in contact with
the arm, so that remove the power sup-
ply (by removing 4 wood screws) and
mount it right-handed.
12

(3) Attachment of the Chin-rest
and Head Rest Section
Unscrew, with the screwdriver four(4)
attachment screws on the chin-rest
attachment mounted below the table.
Place the cord in the gap between the
chin-rest attachment plate and the table
and confirm the cords are not caught
between plate and chin-rest section, fix
the chin rest section with four screws.
(4) Connecting the cord
Connect the cords of chin rest section.
and power cord to the power supply.
Remove the cord holders 4 . Pass the
cord through the cord holder 44 fitted
to the lower face of table and fix it.
Fig. 16
(5) Checking the electric plug
Check whether the electric plug connected to the power cord matches that of
13

(6
the room receptacle. If not, exchange it for a suitable one. On the other hand, the
electric plug may not be connected at all, because of specialiazed requirements
in your region, in which case, connect a suitable plug.
There are three electric wires in the power cord.
Among three wires, the green/yellow(or green) wire should be connected to the
grounding terminal.
Setting up the Base
Simply place the base section on top of the
tablet), with the outrigger rollers aligned on
top of the toothed rails (7).
Next, insert the rail covers(8) in place, over
the rails. Insert the flange, on the base of
the cover, between the slight opening which
exists between the rail and the surface of
the table. (See Fig. 17)
Tighten the base fixing screw(9) to facilitate
further work. .
Fig. 17
(7) Attachment of the Slit Lamp Arm
Loosen the microscope arm fixing knob screw and rotate the microscope arm
19 60º or 90º to the right or left, from its central position, which will be more
convenient for attaching the slit lamp arm.
Next, loosen the setscrew protruding on the outside of the slit lamp arm's at-
tachment socket so that it no longer protrudes inside the socket.
Finally, lower the slit lamp arm carefully into position, as in Fig. 18, while, at the
same time, lining up two red dots. When properly aligned, screw :n the setscrew
tightly, as in Fig. 19, so that the slit lamp arm cannot be deiached.
Fig. 18 Fig. 19
Connect the cord which is found on the chin-rest with the Lamphouse coverá)
14

(8) Fixing the Chin-Rest Pads
Pull out the pad fixing pins, on both sides of
the chin-rest, by, first, pushing them up
from below.
Next, take a suitable quantity of the pads
and place them on top of the chin-rest.
Finally, fix them in place, by passing the two
pad fixing pins through the openings of the
pads. (See Fig. 20)
Tear off one tissue pad each, after examining
a patient, which will place a new one in place
for the next patient. Fig. 20
(9) Storage of Accessories
Store the standard accessories supplied with the instrument in the accessory
drawer(2), as shown in Fig. 21, in the case of table).
When the Slit Lamp is used on the lower instrument arm of the ophthalmic
stand, there is no accessory drawer and the standard accessories should be
stored in the box supplied for this purpose. (See Fig. 22)

(5. OPERATIONS
1) Preparations
(1)
(2)
(3)
Use the instrument in a dark room
Insert the plug of the power cord@3 into the nearest convenient room receptacle
Confirm that the grounding was completed
Set the beam splitter lever to “OUT”.
(VIN" is used in case of photography)
Insert the test rods4ğ into the opening on top of the post around which the
microscope arm and slit lamp arm rotate
Switch on the power switch@) and check whether the slit illumination lamp@
and the fixation target lamp are illuminated or not.
Project a suitable slit image on the test rod@8).
Revolve the slit width adjusting wheel@ to adjust the width of the slit and revolve
the milled knob of the slit diaphragm plate handle65, around the axis of the handle,
to change the length of the slit.
The cross-scales seen in the field of view of one of the eyepieces@ is used for
adjusting the eyepieces to the user's eyesight. (The cross-scales can be placed
in the field of view of either eyepiece, as found suitable.)
The eyepiece, in which the cross-scales can be seen, should be used for making
dioptric adjustments for both eyes of the operator, with the required dioptric
power for the other eye transferred to the other eyepiece.
Dioptric adjustments are made by, first,
drawing out the eyepiece lens fully, by re-
volving the eyepiece adjustment ring. This
will result in the cross-scales appearing
blurred and indistinct. Next, slowly turn the
eyepiece adjustment ring in, until the cross-
scales are seen clearly and distinctly and
then stop. If the eyepiece adjustment ring
is revolved beyond the point of clear focus,
then draw the eyepiece lens out completely
once and repeat the adjustment.
The eyepiece adjustment ring has a dioptric
scale engraved on it, with each scale division Fig. 23
representing one diopter. If you can remem-
ber the dioptric adjustments for both eye-
pieces, it will only be necessary to set the
adjustment rings to the required settings on
the scales of the eyepieces, without going
through the above adjustments each time.
(Fig. 23)
Adjust the pupillary distance.
The pupillary distance between the binoc-
ular eyepieces is adjusted by simply rotating
the prism housings outwards to increase the
distance and inwards to decrease the dis-
tance. Fig. 24
The adjustment range is from 55mm to
75 mm, (See Fig. 24)
When the pupillary distance is adjusted
