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.
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.
Take care never to look into the end of a fiber or any other optical
component, when they are in use. This is because the laser can seriously
damage your eyes.
