Optical Maintenance
a.
Do not attempt to disassemble any lens component. Consult an expert technical service company
when repairs not covered by these instructions are required.
b.
Prior to cleaning any lens surface, brush dust or dirt off lens surfaces using a camel hair brush. Or use air
to blow dust and lint off surfaces. Compressed air, available at any computer supply store, is a good
source of clean air.
c.
Cleaning eyepiece lenses.
Do not remove eyepiece from eyepiece tube. Clean only the outer surface. Breathe on lens to
dampen surface, then wipe with lens paper. Do not wipe lens surface while dry as lenses are
scratched very easily. Wipe in a circular motion from center to outer edges.
d.
Cleaning objective lenses.
Do not remove objective lenses from the microscope. Clean front lens element only. Using a cotton swab
saturated with distilled water, clean front lens surface. Inspect the lens using a magnifying glass to insure
that the element is clean. If immersion oil or specimen material of any kind is evident, use a cotton swab
dipped in a small amount of Windex to clean all foreign material from objective lens surface. Such material
will reduce or totally block, image quality.
e.
Cleaning condenser lens.
Clean only the top lens surface, visible when looking through hole in top of stage. Use same procedure as
used for eyepiece or objective lenses.
f.
Illuminator condenser lens.
Use same procedure as used for eyepiece or objective lenses.
