OPERATION PROCEDURES
(6) Reflection mirror
Two mirrors are supplied with the SL-3E. One is a long mirror and the other is a short mirror
which has no protruding surfaces. Usually, for most examinations, the long mirror is used.
However, when the angle between the illumination unit and the microscope is within approxi-
mately 3° to 10°, the observed image is disturbed. In this case, use the short mirror.
When using the short mirror, incline the illumination unit to more than 10°.
* Replacing the mirror
1) Set the angle between the microscope and illumination arms to exceed 30°.
2) Incline the illumination column at 10° or more.
3) Remove the long mirror by holding on to the extended surface.
4) Insert the beveled side of the short mirror.
5) When removing the short mirror, since it has no extension, use an object with a sharp end
to carefully push it out as shown below.
(7) Filter selection
By shifting the filter selection lever, four different filters can be inserted into the illumination
pathway.
Usually, the heat absorption filter is used for patient comfort.
