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.
