When To Check; Supplies For Removing Dust And/Or Grease; Cleaning Lens; Cleaning Reflector - Christie CP2000 Setup Manual

WHEN TO CHECK

Lens: A small amount of dust or dirt on the lens has minimal effect on image quality. To avoid the risk
of scratching the lens, clean the lens only if absolutely required. For more information, refer to
Cleaning Lens, on page 2-7.
Lamp Reflector: Inspect the mirror surface (reflector) for cleanliness only during lamp replacement,
when the lamp is out. Wear protective clothing while inspecting or cleaning. Note that the color on the
reflector surface may vary - this is normal. For more information, refer to
page 2-7.

SUPPLIES FOR REMOVING DUST AND/OR GREASE

• Soft camel-hair brush
• Dust-free blower-filtered dry nitrogen blown through an anti-static nozzle
• Dust-free lens tissue, such as Melles Griot Kodak tissues (18LAB020), Optowipes (18LAB022),
Kim Wipes or equivalent
• Lens cleaning solution, such as Melles Griot Optics Cleaning Fluid (18LAB011), or equivalent (for
lens only)
• Methanol (for reflector only)
• Cotton swabs with wooden stems only
• Lens cleaning cloth/microfibre, such as Melles Griot (18LAB024), or equivalent

CLEANING LENS

Removing Dust
1. Brush most of the dust off with a camel-hair brush and/or blow dust away with compressed air.
2. Fold a microfibre cloth smooth and gently wipe remaining dust particles from the lens. Wipe
evenly with the smooth portion of the cloth that has no folds or creases. Do not apply pressure with
your fingers - use tension in the folded cloth to collect the dust.
3. If significant dust is still bound to the surface, dampen a clean microfibre cloth with lens cleaning
solution (damp, not dripping). Wipe gently until clean.
Removing Fingerprints, Smudges, Oil
1. Brush most of the dust off with a camel-hair brush and/or blow dust away with compressed air.
2. Roll a lens tissue around a swab and soak in lens cleaning solution (damp, not dripping).
3. Gently wipe the surface using a figure-8 motion. Repeat until blemish is removed.

CLEANING REFLECTOR

Removing Dust
1. Brush most of the dust off with a camel-hair brush and/or blow dust away with compressed air.
2. If some dust remains, leave as is - air circulating at the lamp is unfiltered, so some dust is
inevitable. Avoid unnecessary cleaning.
