Scan Optics microscopes are supplied with two sets of sterilisable covers – one set may be used while
the other set is undergoing sterilisation. Additional sterilisable covers may be purchased from Scan
Optics in the event of loss or damage.
The covers may be sterilised by:
boiling
autoclaving
chemical sterilisation
gas sterilisation.
Note that national authorities may require the use of specific sterilisation or disinfection methods.
"
Note that sterilised covers should be applied to the manual focus and zoom knobs and the guide
handle (if used) before these parts of the microscope are touched by a sterile operator.
1. Move the head into approximate position using the arm assembly articulations.
2. Use the foot control to move the microscope focus up to the half-way position. This is indicated
by the two black dots on the left hand side of the microscope head, and will leave approximately
25mm of movement up or down from the central position.
3. Use the manual focus knob or optional side handle to move the head up or down while looking
through the eyepieces to roughly focus the microscope.
4.
If the microscope eyepieces are higher than the most comfortable position for the operator and it
is not possible or practical to adjust the operator’s seat, rotate the tilt knob clockwise to tilt the
head of the microscope down. The range of tilt adjustment is from 45° downward to 5° above
the horizontal.
Focussing the microscope in the correct sequence is an important step in setting up for use.
1. Set the pupillary distance of the microscope by moving the eyepieces apart or together as
required. The eyepieces are geared together and will move equal distances on either side of the
optical centre of the microscope.
2. Set the refractive error scale to zero on the LHS eyepiece.
3. Choose a high magnification zoom setting or one which is typically used in surgery.
4. Close the left eye and look through the right eyepiece of the microscope with the right eye only.
5. Focus the microscope slowly until the image is sharply in focus.
6. Close the right eye and look through the left eyepiece of the microscope with the left eye only.
7. Rotate the refractive error adjustment ring on the left eyepiece until the left eye is in focus. The
reading on the ring will give an approximate measure of the relative refractive error between the
left and right eyes.
8. Look through both eyepieces normally and check that the image is focussed and that stereopsis
is achieved.
