3.1.2.2 Light Manager
The Light Manager is automatically activated each time the Axiovert 200 is switched on.
The Light Manager automatically sets the illumination intensity of the halogen illuminator last saved for
each individual objective position. Therefore, the correct brightness is immediately available in almost all
cases.
During the objective change, the lamp voltage is reduced automatically to avoid glare and to permit the
required brightness to be achieved sooner.
FL key on / off for fluorescence shutter
If this key is pressed briefly, the optional fluorescence shutter (reflected light) can be opened or closed.
Opening is confirmed by a beep. The Light Manager remembers the setting of the halogen illuminator
separately for the opened and closed shutter and resets it automatically after a changeover, i.e. the
correct lamp brightness is always available immediately after any change between reflected and
transmitted light.
☞
This function of the fluorescence shutter key is also beneficial for pure transmitted-light
operation to change quickly and easily between two different settings of the lamp brightness,
e.g. in the following cases:
− change between the brightfield and darkfield contrasting technique,
− change between differently absorbing filters in the beam path,
− change between visual observation and documentation using a camera.
Programming of switching status
The individual settings of the Light Manager can be saved permanently so that they are always available
immediately when the instrument is switched on.
• To save the Light Manager parameters, briefly press the Set LM key on the instrument rear. Saving as
switching status is confirmed by a beep. LightManager Settings stored appears in the LCD display.
