Maintenance
Only use isopropyl alcohol in your ultrasonic bath, as other
solvents may cause damage.
Warm water and liquid soap Only use water if you are sure that
there is no other way of cleaning your optical device without
causing corrosion or damage. Do not use water that is too hot or
too cold, as this may cause mechanical stress, which can
damage your optical device.
Ensure that your liquid soap has no abrasive properties or
perfume in it. You should also avoid normal washing-up liquid,
as it can cover your device in an iridescent film after it has been
air-dried.
Some lenses and mirrors also have a special coating, which may
be sensitive to mechanical stress, or to fat and liquids. For this
reason we recommend you do not touch them.
If you are not sure how sensitive your device is to cleaning,
please contact the manufacturer or your sales distributor.
Premoistened cleaning wipes Use pre-moistened cleaning wipes
as described in each individual cleaning procedure. Cleaning
wipes may be used in every instance where a moistened soft
tissue or cotton swab is applied.
Lens cleaning papers Some special lens cleaning papers are not
suitable for cleaning optical devices like connectors, interfaces,
lenses, mirrors and so on. To be absolutely certain that a
cleaning paper is applicable, please ask the salesperson or the
manufacturer.
Polymer film Polymer film is available from laboratory
suppliers or specialist mail order companies.
Using polymer film is a gentle method of cleaning extremely
sensitive devices, such as reference reflectors and mirrors.
Infrared sensor card Infrared sensor cards are available from
laboratory suppliers or specialist mail order companies.
With this card you are able to control the shape of laser light
emitted. The invisible laser beam is projected onto the sensor
card, then becomes visible to the normal eye as a round spot.
