Section 6: Maintenance
Laserglow's Virtualine™ LED SWITCH fixtures require very little maintenance. Depending on the cleanliness of your
environment, maintenance may be required with some regularity, or never at all. Inspect the fixture regularly to ensure
there is no buildup of debris or dust on the output lens or rear heatsink.
CLEANING THE OUTPUT LENS
Depending on the operating environment, it is possible that some dust may accumulate on the output lens of the projector.
You can use a can of clean compressed air to try to blow the dust off of the lens or use a soft cloth to wipe away any
debris. Do not use alcohol or any other chemicals to clean the lens – doing so may cause irreversible damage to the lens
and is not covered under warranty.
If these steps fail to improve the quality of the beam please contact us for further assistance.
NEVER USE tissue paper, paper towel, facial tissues, etc.
The wood fibers in these products can damage
the coatings on the lens.
NEVER USE cleaning solutions other than those explicitly mentioned here.
The lens coatings are
delicate and can be damaged by common cleaning products. NEVER touch the lens or other optics with your
fingers as oil from your skin can contaminate and damage the coatings. Failure to follow these warnings can
result in damage to your laser which will not be covered by warranty.
1. Compressed air:
You can use a can of clean compressed air to try to blow the dust off of the lens without
making physical contact with the lens itself. These are commonly used to clean computer keyboards and can
be purchased at any office supply store. They usually have a long tube or nozzle attached to them. Carefully
insert this tube a few mm into the aperture of the laser to blow air over the lens. Be careful not the touch the
lens with this tube. Hold the can upright or it may produce some liquid which can leave deposits on the lens.
2. Microfiber cloth:
If there are deposits on the lens that cannot be removed with compressed air, you can
try using a microfiber lens cloth to gently wipe the output lens. Ensure that the microfiber cloth is clean before
you use it, since any oil, dirt, or grit may damage the lens. Since the lens is slightly recessed in the housing,
you may need to twist the microfiber cloth into a small "finger" to get it deep enough into the aperture to make
contact. If you still cannot reach the lens with the cloth, you may need to remove the aperture cap from the
front of the laser: DISCONNECT THE POWER BEFORE PROCEEDING. Remove the three set screws from
the aperture cap and thread the cap all the way off. The output lens should now be exposed, and you can
attempt to clean it using the microfiber cloth.
3. Microfiber cloth and lens cleaning solution:
If a cleaning solution is required use ONLY a specifically
designed lens cleaning solution. (Available from camera stores or optics companies.) Use a very small
amount and wipe the lens only with a microfiber lens cloth. Do not use any other type of cleaning solution or
you may permanently damage the lens.
