6 OPTICS CARE AND CLEANING
6.1 OPTICS CARE
- Never touch the polished surface of optics.
- Hold an optic only by its edges.
- Reduce the need for cleaning optics as much as possible.
6.2 OPTICS CLEANING
- Use latex gloves when handling or cleaning optics.
- Do not reuse cleaning materials.
SPECTROMETER MIRRORS, ND FILTERS, QUARTZ PRISMS AND LENSES: In the event of
dust, blow off with rubber hand pump (avoid using your breath) or use bottled dry nitrogen to
remove particles. In the event of grease or fingerprints, dampen a very soft cloth with methyl ethyl
alcohol and wipe gently. NOTE: Wipe marks will almost certainly remain. To remove the wipe
marks, dampen a soft tissue with a mixture of ether and isopropyl alcohol and wipe gently. The
tissue should be dampened to the extent that while wiping, the mixture evaporates one to two
millimeters behind the tissue.
QUARTZ DOME AND EXTERIOR QUARTZ WINDOW: Spray with window cleaner and wipe clean
with a soft cloth.
LAMPS: Dampen a soft cloth with methyl or ethyl alcohol and wipe gently.
POLARIZING FILTER: Use only a soft, dry cloth or tissue to remove dirt and finger marks. The filter
should always be wiped gently to avoid marring the finish.
DIFFRACTION GRATINGS: Do NOT touch or attempt to clean.
