Care and Cleaning
26.3 Cleaning Immersion Lenses
The immersion oil should be removed from oil immersion lenses immediately after it is
applied:
1. First, remove the immersion oil using a clean cloth.
2. Once most of the oil has been removed with a clean tissue, a piece of lens tissue should
be placed over the immersion end of the lens.
3. Apply a drop of the recommended solvent. Gently draw the tissue across the lens
surface.
4. Repeat this procedure until the lens is completely clean. Use a clean piece of lens tissue
each time.
Caution when objective lens is contaminated
If an objective lens is contaminated by unsuitable immersion oil or by the
specimen, please contact your local Leica branch office. Certain solvents
may dissolve the glue which holds the lens in place.
26.4 Care
• Always keep the optical components of the microscope clean.
• Never touch the optical components with your fingers or anything which may bear dust
or grease.
•
Always place dust caps over the objective nosepiece positions when no objective is in
place in the nosepiece
.
• When not in use
,
cover the system with a plastic cover or a clean piece of cotton cloth.
Avoid condensation
Allow the entire system to cool down to room temperature before
covering the system with a dust cover. This prevents condensation from
forming below it, which can enter the system and damage it.
