Cleaning the projector optics

Learn about cleaning the optical components in the projectors.
Unnecessary cleaning of optics, increases the risk of degrading delicate coatings and surfaces. Only
clean optics when dust, dirt, oil, fingerprints or other marks are obvious and are causing performance
problems. Maintenance of optical components requires a qualified service technician. Inspect exposed
optical surfaces periodically in a clean, dust-free environment using a flashlight.
Never touch an optical surface with your bare hands. Always wear latex lab gloves.
Use the following products when cleaning the optical surfaces:
• 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), Opto-wipes (18LAB022),
Kim Wipes or equivalent
• Cotton swabs with wooden stems only
• Lens cleaning cloth/microfibre, such as Melles Griot (18LAB024) or equivalent

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.
1. Brush most of the dust off with a camelhair brush or use a dust-free blower.
2. Wrap a lens tissue around a swab and soak it in lens cleaning solution.
The tissue should be damp but not dripping. Do not use a cleaning solvent that contains
ammonia. Avoid lens contact with Xylene and Ether.
