Cleaning the optics

• If the optical parts need to be cleaned try first to: use compressed air.
• If that is not sufficient: use a soft lint-free piece of cloth with water and a mild detergent.
• And as a final option: use the piece of cloth moistened with a 3:7 mixture of ethanol and
ether.
note: ethanol and ether are highly flammable liquids. Do not use them near a heat source,
near sparks or near electric equipment. use these chemicals in a well ventilated room.
• Remember to never wipe the surface of any optical items with your hands. Fingerprints can
damage the optics.
• Do not disassemble objectives or eyepieces in attempt to clean them.
5.5 Changing the incident lamp bulb
before changing the bulb, make sure that the power switch is off and the power cord has been
disconnected from the main supply.
unscrew the lamp collector piece and pull it out, remove the old light bulb from the socket,
and carefully plug the new bulb in. Screw the collector piece back after changing the bulb.
never touch the glass surface of the bulb with naked hand, any grease stain brought onto the
bulb by the hand will negatively affect the heat dissipation, and thus, greatly shorten the life
span of the bulb. Clean the bulb surface with alcohol and tissue if the user has touched the
bulb surface accidentally.
