6) Reflecting mirror
Both short and long reflecting mirror
are available in this instrument. Use
the long mirror in normal examination.
When the angle between the
illumination part and the microscope
is within 3o to 10o, the examined
image might be obstructed. In this
case, use the short mirror. The short
mirror is also used when the
illumination part is inclined over 10o
(Fig.31).
4) Deflecting the illumination light
Loosen the centering knob (25) and
swing the slit width control knob (23)
back and forth so the light spot moves
away from the center of the
microscope vision field . It is mainly
used to examine the eyes by indirect
retro-illumination.

7) Filter selection
Turn the filter selection lever (31) in
the horizontal surface to add four
different kinds of filters respectively
into the illumination pathway. Usually
the heat-absorbing filter is used so
that the patient may feel more
comfortable in long period of
examination (Fig.32).
Fig.29
5) Oblique illumination
Oblique illumination is used for
sectional or fundus examination by
using contact lens. Press down the
inclination lever so that the
illumination part may incline to 20o,
(5oof each division). Since the
illumination part may touch the
patient’s head, operate carefully

3.5 Fundus observation with Hruby lens (optional)-------------------------In routine using, the observation with
the slit lamp is limited within the
range from the cornea to the anterior
part of the vitreous body owing to
refraction effects of the cornea and
the crystalline lens. However with the
Hruby lens (I) in the front of the
microscope, the posterior part of the
vitreous body and fundus then can be
observed.
7) To examine different parts, either turn
the microscope and the illumination
arm or change the patient’s fixation
by manipulating the fixation target.
8) If the long mirror interference in the
examination, just replace it with the
short mirror.
9) After examination, move the Hruby
lens back to the original position on
one side of the chin-rest.
Operation procedure:
1) The pupil should be dilated for about
20 minutes.
2) Insert the Hruby lens guide plate (15)
into the main shaft hole of the
illumination and the microscope arm.
Attention: before moving the
Hruby lens to the right and
left, first have the patient’s
head move away from the
chin-rest to avoid his nose
touching the Hruby lens.
3) Pull out the Hruby lens holder from
one side of the head-rest as shown in
Fig.33. Move the Hruby lens holder
toward the operator so that it can slide
freely to the left and right below the
chin-rest. Insert the lower end of
Hruby lens lever into the groove on
the guide plate.
4) Move the focus of the illumination
light and the microscope to the
patient’s eye.
5) Move the lever to locate the Hruby
lens at the center of the vision field
and near the patient’s eye as shown in
Fig.33.
6) Move the lever to focus the Hruby
lens at the fundus, then adjust the slit
height and width to reduce the
unnecessary inter-ferrential light in
the vision field.
