Lighting Control; Using External Illumination Units - KERN Optics OZL 46 Series User Instructions

5.7 Lighting control

The microscopes in the OZL-46 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 central rear section of the stand base.
The control knob to the right of the main switch is responsible for the adjustment
of the light intensity of the transmitted illumination.
The same functions belong to the control knob to the left of the main switch
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 OZL-46 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.

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. For halogen lighting units, the light source is in the
housing of the unit and is emitted through one or several optical fibre cables. For
LED units, on the other hand, it us usually at the end of the cable.
These cables are flexible and therefore offer a large number of positioning options,
so that the object being observed is perfectly illuminated.
