11.1 Cleaning of lenses and protective windows

The surfaces of lenses and protective windows are susceptible to scratching. Improper cleaning can
cause damage.
Lenses generally shall be treated so that cleaning is not required. Avoid smudging lenses by only
handling while wearing protective gloves, preferably made of cotton.
Do not clean the lenses and windows unnecessarily. If cleaning is unavoidable, clean the surfaces
only as intensely as necessary.
At the beginning of cleaning, first remove dust and loose particles by blowing with filtered oil-free
compressed air (for example with a small bellow or canned, compressed air) or with a camel hair
brush.
For easier cleaning of adhering particles, please only use a clean, lint- and fibre-free cloth (unused
lens cleaning or microfibre cloth, wood-free pulp cloth). If necessary, add a drop of cleaning solution
(see below) to the centre of the cloth. Run the cloth slowly over the lens surface without applying
pressure. After wiping, both the cloth and the surface of the lens should be nearly dry, meaning that
no smearing or smudges should remain.
For strongly adhering dirt or fingerprints, if necessary, a gentle uniform pressure may be applied.
For such instances, surgical cotton or cotton swabs may be suitable for use, in addition to the types
of cloths listed above. These can be moistened with a few drops of cleaning solution. Excess
solution should be shaken off before use by shaking the cloth, cotton or cotton swabs.
Wipe extremely slowly and only in one direction. Rapid wiping in multiple directions can cause
scratches. Use a new cloth, cotton or cotton swab for each cleaning.
The only suitable cleaning solutions are ethanol or methanol.
If smudges persist even after following these steps, please contact InfraTec service.
