1. INTRODUCTION
Although this product features the same basic principles as the photographing device used with the SL-7F/7E,
8Z, the following main improvements have been performed: clear view and greater operational ease.
1-1 Features
•There are five types of camera (TV camera) to take a photograph: Nikon D1, Fuji S1 Pro or S2 Pro,
JVC KY-F70, SONY DXC-390 and Topcon DC-1. The user can select a camera.
The above are main features which are different from the photographing device used with the SL-7F/7E, 8Z.
1-2 Target Users of This Manual
This is optical equipment designed for ophthalmic testing. This manual is intended mainly for those experi-
enced in handling optical instruments, including repairs and adjustments. Those who have no experience in
those areas should take the repair course sponsored by Topcon.
1-3 How to Use This Manual and Precautions
1-3-1 Precautions for repair
(1) Carry out repair, assembly, disassembly and adjustment on optical systems in clean areas where no dust or
foreign matter will affect instrument performance.
(2) Refer to the SL-D7/accessories assembly and instruction manuals regarding assembly and inspection.
(3) Always carry out repairs according to the instructions in this manual, by using the specified materials and
tools.
(4) Compilation of instructions in this manual is based on the assumption that metal parts must be changed as
a single part and optical components by individual units.
(5) Refer to the service parts list for disassembly and assembly of parts not described in this manual.
(6) Never use grease or sealant except when specified by this manual.
(7) Order parts using the name and numbers found in the service parts list.

2-2 Adjustments
* Before carrying out adjustment, if the screw lock has been applied to any screw, dissolve it using Isoamyl
acetate.
2-2-1 SR-52
Illustration Procedure
(1) Focusing
The photographic focal point is poor and pho-
tographs are not clear.
Attach SR-52 to the main unit, turn the magni-
fication drum to 16× and project the φ10 aper-
ture on the test bar.
Remove the aperture frame (45520 1112).
Attach the focus positioning tool to the camera
mount unit.
Lower the return mirror with your finger and
make sure that the scale line on the focus posi-
tioning tool is fit to the focus on the test bar
surface.

Illustration Procedure
If the focus is off, remove the rubber cap,
loosen the hexagonal screw, and move the tool
up and down to where the focus is best. After
adjusting the position, apply the screw lock and
attach the rubber cap.
Project the φ0.2 aperture on the test bar and, as
looking into the focus positioning tool, check
the amount of shift.
When the optical axis is shifted, carry out posi-
tioning of optical axis.
* Refer to "(2) Positioning of optical axis" in P.17
and P.18.

Illustration Procedure
When the optical axis is shifted by 1mm or
more in the right-and-left direction:
Loosen the 3 screws CR2×4S and move the one
side of the mirror holder (1011) up and down
for adjustment.
After adjusting accuracy, tighten the 3 screws
CR2×4S securely and apply the screw lock.
When the optical axis is shifted by 1mm or
more in the up-and-down direction:
Loosen the 1 piece 1N2.6, adjust 1 piece
U2.6×6S and bring the optical axis to the cen-
ter.
