5.7 Lighting control
The microscopes in the OSF-4G series have an adjustable
reflected and
transmitted light illumination
.
The power supply is guaranteed by connecting the mains cable and pressing the
main switch on the right, rear corner
.
The
control wheel
on the righthand side surface
of the stand base is responsible
both for
on-/off-switching
and the adjustment of the
light intensity
of the
transmitted illumination
.
The same functions
belong to the
control wheel on the lefthand side surface
of
the stand base according to the
reflected illumination
.
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 OSF-4G 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.
