INFO
Do not clean the internal optical surfaces. Touching or cleaning these surfaces
may lead to serious damage to the optical system.
Cleaning the Optical Surfaces To clean the external optical surfaces of components:
Procedure 1 Switch the device off completely and pull the mains plug.
2 Remove the component from the microscope or move the stage so that the
component can be accessed.
For a list of components that can be removed and the corresponding
instructions, see Disassembling the Microscope [

3 Gently rub the optical surfaces with an optical cleaning cloth dipped in an
optical cleaning solution (mixture of 85% petroleum ether and 15%
isopropanol).
– Rub the surfaces in a circular motion from the center outwards.
– To avoid scratches, do not use dry lens paper or a dry cloth.
– Make sure that no fluid enters the system.
4 Once the optical surfaces have dried, reinsert the component into the
microscope.
