7.0 MAINTENANCE

7.1 Lens Cleaning

Materials:
•
Optical-grade tissue (e.g., Edmund Industrial Optics part number 52105 or any similar product)
•
pure water (de-ionized or other)
•
isopropyl alcohol (IPA)
Procedure:
1. Saturate a piece of the lens tissue with the water and drape it over the lens. Let the surface
tension of the water pull the tissue onto the lens surface and then drag the tissue across the
lens surface. Repeat several times with different pieces of tissue.
2. Repeat the same step using IPA instead of water. Drag the final piece of tissue over the lens
several times to prevent pooling, which could leave a residue behind.
