Cleaning and care of the microscope
Changing the bulb
Before changing the bulb, make sure that the power switch is off and the Power cord has been
disconnected from the main supply.
For Incident light, unscrew the lamp collector piece 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.
For transmitted light, remove the stage glass plate by pushing down its rear side, and move the old bulb
from the socket and carefully plug the new bulb in.
Never touch the glass surface of the bulb with naked hand, any grease stain brought onto the bulb by the
naked hand will negatively affect the heat dissipation, and thus, greatly shorten the life span of the bulb.
Clean the bulb surface with Ryf Lens Cleaner or alcohol and tissue if the user has touched the bulb
surface accidentally.
Cleaning
lf dust is found on the optical surface, try to remove by air blower or better with canned air (Ryf cleaning
Set).
For fingerprint, grease stain or dust which cannot be removed by the air blower possible methods are
recommended:
•
To breathe lightly on the glass surface and wipe with a clean piece of cloth, lens paper or cotton
swab.
•
Please notice that small cotton fiber may be left onto the lens surface if cotton swab is used.
•
Use a cotton swab or lens paper dip with a small amount of absolute alcohol (or better with Ryf
cleaning Set) and clean the lens surface carefully. No other aggressive solvents should be used.
•
In no circumstances should the user clean any lens surface with dry cotton swab, cloth or lens
paper. This will scratch the lens surface causing irreparable damage.
•
Water is not recommended fop cleaning of lens as it will leave some water stain on the lens
surface and if water residue is left on the lens, fungus can grow causing irreparable damage.
