11G-50 UltraScan VIS
The fluorescent standard used with the UV control feature must be cleaned as well. This plastic
standard can be cleaned with a weak liquid detergent solution and rinsed with distilled water.
Cleaning the Lens Surface and Didymium Filter
The lens and filter may be cleaned using photographic-quality lens solution and lens paper. Put a few
drops of solution on the lens paper and gently wipe the lens or filter in a circular motion for a few
seconds. Then wipe the lens or filter with a dry lens paper to remove streaks and any hazy film.
Cleaning the Sphere
Care should be taken to keep foreign materials from entering the sphere. The transmission compartment
should be closed and the sample clamp placed against the reflectance port when the instrument is not in
use. The sphere is coated with Spectraflect™, which can be damaged by putting any objects into the
sphere. If any foreign material (dust, lint, etc.) falls into the sphere, use the following steps to remove
the material.
1. Move the sample clamp away from the reflectance port.
2. Open the transmission compartment and place a vacuum cleaner hose at the sphere opening but do
not insert the hose directly into the sphere. Cup your hand around the end of the hose to provide a
good seal.
3. Quickly cover and uncover the reflectance port with your other hand. This creates gentle air currents
to swirl the foreign matter around and out of the sphere.
When shipping the UltraScan VIS, remove the sample clamp and tape a pad of foam rubber at the
reflectance port. Failure to do so may cause severe damage to the instrument.
