Care and Maintenance 

1.  Do not attempt to disassemble any component including eyepieces, objectives or 

focusing assembly.   

2.  Keep the instrument clean; remove dirt and debris regularly. Accumulated dirt on 

metal surfaces should be cleaned with a damp cloth. More persistent dirt should be 
removed using a mild soap solution. 

Do not use organic solvents for cleansing

3. 

The outer surface of the optics should be inspected and cleaned periodically using 

an air stream from an air bulb. If dirt remains on the optical surface, use a soft cloth 
or cotton swab dampened with a lens cleaning solution (available at camera 
stores). All optical lenses should be swabbed using a circular motion. A small 
amount of absorbent cotton wound on the end of a tapered stick makes a useful 
tool for cleaning recessed optical surfaces. Avoid using an excessive amount of 
solvents as this may cause problems with optical coatings or cemented optics or 
the flowing solvent may pick up grease making cleaning more difficult. Oil 
immersion objectives should be cleaned immediately after use by removing the oil 
with lens tissue or a clean, soft cloth. 

 

4. 

Store the instrument in a cool, dry environment. Cover the microscope with the 

dust cover when not in use.
