12.3 Cleaning Optical Components

The places on the device where lubricants and adhesives are to be found are
displayed in part C in the figures and indicated by numbers
Lubricants are only allowed to come into contact with designated places,
since they can dissolve or damage plastics.
• Clean and dry parts before using lubricant.
12.3 Cleaning Optical Components
• Keep the optical system of the microscope clean at all times.
• Observe that optical components are not contaminated with dust, grease or other
dirt.
• Keep the tools, auxiliary equipment and work place clean at all times. This is a
prerequisite for successfully cleaning optical components.
• Check the condition of the optical parts before you begin cleaning them. To do so,
use a cotton cloth or a hair pencil to wipe them at a place where no light beams
pass through the optical medium (for example, at the edge). If you find traces of
wiping, the surface coating is soft and it will hardly be possible to be cleaned
without damaging the coating.
• To clean the optical part (for example illuminating lens or mirror), remove it from
the mount if possible.
• Never open the objectives for cleaning.
