Maintenance
The eyepieces and objectives on VanGuard Microscopes are coated. They should never be wiped while dry
as
any dirt or dust will scratch the coating. The surfaces should either be blown off with an air canister, or
blown
and cleaned with an air-bulb and camel-hair brush. It is recommended to then use a lens cleaner.
Never use anything other than lens cleaner on any optical component.
Apply with a cotton swab for a
minimum of wetting, then wipe the surface clean with a quality lens tissue.
The same care instructions apply to all optical parts on this VanGuard Microscope, including the substage
collector and the condenser lenses.
All other parts can be cleaned with a paper towel and rubbing alcohol. Be aware that rubbing alcohol can
break down lubricants, so be careful when cleaning near the following parts:
Stage rack and pinion gears
Focus controls
Nosepiece
Substage gears
Substage controls
Xylene, since it breaks down the bonding material holding the lenses, should never be used as a cleaner.
Periodically your VanGuard Microscope should be fully serviced by a qualified service technician.
In order to keep dust and debris out of the optical pathways, always keep the camera port and eyetubes
covered (with either eyepieces or dust caps), and always use the dust cover when the microscope is not in use.
