Inspecting and cleaning optics
Inspect and clean optical components such as the projection lens to ensure optimum image display.
Unnecessary cleaning of optics can increase the risk of degrading delicate coatings and surfaces. 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.
Typically, optical components do not need to be cleaned frequently if they are installed and operated in
a location that meets or exceeds the environmental standard recommended by Christie. Christie
recommends that all cinema projectors are installed and operated in an environment that meets or
exceeds Underwriters Laboratories (UL) standard 609.50 Pollution Degree 2 and ISO Class 9 Standard
for Office Environments.
Notice. If not avoided, the following could result in property damage.
•
Christie products must be installed and serviced by Christie qualified technicians.
•
Do not reuse lens tissues.
•
Always handle optics by their edges.
Recommended service kit
Use the following recommended tools to clean the optics.
•
Powder-free latex gloves
•
Soft camel-hair brush
•
Dust-free blower - air bulb or a canned air duster without additives such as Techspray 1671-
10S Ultra-Pure Duster
•
Lint-free lens tissue, such as Lensx 90 tissue or Newport Optics cleaning tissue
•
Lens cleaning solution and a microfiber cloth (for the lens only)
•
Optical grade cotton swabs with wooden stems
•
A bright, portable illumination device such as an LED flashlight
Cleaning the lens
To avoid the risk of scratching the lens, clean the lens only if absolutely required.
Removing dust from the projection lens
Remove dust from the projection lens to ensure optimum image display.
1. Brush most of the dust off with a camel-hair brush or use a dust-free blower.
2. Fold a microfiber cloth and wipe the remaining dust particles off the lens with the smooth
portion of the cloth that has no folds or creases.
Do not apply finger pressure. Instead, use the tension in the folded cloth to remove the dust.
3. If significant dust remains on the lens surface, dampen a clean microfiber cloth with lens
cleaning solution and wipe gently until clean.
Removing fingerprints, smudge, or oil from the projection lens
Remove fingerprints, smudges, or oil from the projection lens to ensure optimum image display.
Clean the lens only if absolutely required.
