SO-5000 Ophthalmic Microscope
POSITIONING THE MICROSCOPE
Note that the equipment must be located more than 25 cm away from any medical gas system or
disinfection or degreasing system containing flammable vapour. The power supply must also be
protected from liquid splashes and spills.
1.
Set the instrument approximately in position by swinging the elbow as required.
2.
Set the focus adjustment to the midway position by rotating the focus knob appropriately.
3.
Adjust the height of the microscope by moving the arm vertically so that the work area is
approximately in focus. Tighten the pillar and elbow lock knobs.
4.
Check the eyepiece setting to ensure clear vision with each eye separately, and set the
pupillary distance. Note that the working distance is increased by rotating both eyepieces in a
clockwise direction, and reduced by rotating both eyepieces counter-clockwise.
5.
The microscope can now be swung aside ready for use with a patient.
6.
Swing the microscope over the patient
7.
Hold the focus knob to move the microscope to the correct position. The most accurate
focusing can be obtained at the highest magnification, as the depth of focus is then minimised.
8.
Tighten the p illar lock k nob until the microscope is prevented from moving freely, but is still
able to be moved when required. The friction of the arm and elbow knobs should be adjusted
so that the movement feels uniform in all directions.
9.
Focus and zoom knobs may be used to manually focus the microscope or manually set the
magnification level, even though a foot control is fitted.
10.
To swing the microscope out of the way, unlock the pillar lock knob and swing the microscope
about the vertical pillar. It will remain in focus when returned to the work area.
