– Never place anything over the open connection to the
light guide. The material covering the connection
could be damaged by heat.
– Never use any part of your body to cover the open
connection to the light guide; you could suffer burns.
– Make sure that the connections to the light guides
are at least several centimetres away from any
materials or objects which are sensitive to heat. The
amount of heat radiation emitted from the light-guide
outlet of a fibre-optic light source is negligible, but it
is possible for objects to convert the intense visible
radiation into heat and to become damaged.
Minimize the time during which the object is illumi-
nated, and also the light intensity.
– When detaching the light guide, avoid touching the
hot inlet of the light guide. Switch off the light source
and wait until the light guide has cooled down.
Immediately above the light guide inlet is shrink-on
tubing that enables the hot light guide to be touched
without danger.
– Do not look directly into the open connector of the
light guide; you could be temporarily dazzled. First
switch off the bulb before you pull out the light guide.
