5.8 Using external illumination units
If, when using a microscope in its standard version, the lighting is not suitable for the
application, then it often makes sense to fit an external lighting unit to overcome this
problem.
The lighting units which are suitable for devices of the OSE-4
series
, are goose
neck lighting units
(see figure)
. These are available as LED as well as halogen
versions and also have an on/off switch or different controller.
Typical goose neck lighting unit
Using goose neck lighting units
Depending on the requirements, a goose neck lighting unit is placed next to, in front
of or behind the microscope. The light source is in the housing of the unit and is
emitted through one or several optical fibre cables.
These cables are flexible and therefore offer a large number of positioning options,
so that the object being observed is perfectly illuminated.
5.9 Changing the bulb
LED
The devices in the OSE-4
series
with lighting are all fitted with LED bulbs.
Due to the long service life of an LED lighting system, for these microscopes it will
not be necessary to simply change a bulb.
Problems with the lighting unit would therefore, in most cases, be caused by defects
in the electrical system. If this is the case, then our Technical Service will be able to
help.
