Axiovert 200
3.2.2.3 Light Manager
The Light Manager is applied with the Axiovert 200 M (storage of set values) in the same way as with
the manual version.
However, the functionality of the Light Manager is considerably greater in the Axiovert 200 M on
account of the coding / motorization of the major microscope components.
The Light Manager is automatically activated each time the Axiovert 200 is switched on. However, there
is the possibility of deactivating the Light Manager temporarily.
Temporary deactivation is achieved by keeping the key FL on / off pressed after the instrument is
switched on until a double beep is emitted. The Light Manager is then deactivated until the microscope
is switched on the next time. LM off appears in the LCD display.
In transmitted light, the following parameters are stored with each nosepiece position:
illumination intensity of the halogen illuminator
condenser turret position (i.e. one contrasting technique, e.g. H, Ph, DIC, per nosepiece position)
aperture stop opening
The intensity value is stored for each Optovar turret position (in combination with an objective), i.e. the
illumination intensity is always suitable after a change of the Optovar magnification. The condenser
turret position does not influence the illumination intensity.
In reflected light, the position of the fluorescence shutter is also taken into consideration.
The position of the reflector turret switches the halogen illuminator and the fluorescence shutter. If a
fluorescence filter set is swung in on the reflector turret, the halogen illuminator is switched off and the
fluorescence shutter is opened. If no fluorescence filter set (brightfield) is swung in or configured, the
halogen illuminator is switched on and the fluorescence shutter is closed.
If the halogen illuminator shall be used parallel to the reflected-light illuminator, it can be switched on via
the Hal on / off key, the illumination intensity can be matched, and this setting can also be stored by
briefly pressing the Set LM key (instrument rear).
Standard settings are performed and stored in the factory for all components integrated into the Light
Manager function.
The settings of the Light Manager can be manually adapted to the available conditions any time.
If manually changed settings shall be stored permanently, this is possible by briefly pressing the SET LM
key. A brief beep after release of the key confirms that storage has been performed.
