Light Manager of motorized microscope
The Light Manager of the motorized microscope (Axio Imager.M2, .M2m, .Z2, .Z2m) controls the light
intensity for the observation of specimens in such a way that for all adjusted magnifications the operator
gets the same impression of image brightness. The operating mode of the Light Manager can be selected
via the Settings menu on the TFT screen (OFF, CLASSIC, SMART). Then, follow this procedure:
•
Select the required contrast method.
•
Adjust the light intensity for all objective nosepiece positions.
•
Press the
LM-Set
button. On doing so, the current settings are transferred to the permanent memory.
They will thus be available again when you switch on the microscope the next time.
The light intensity is changed for all others objective, too, depending on the objective and post-
magnification. When turning on the nosepiece the light manager sets the light intensity as follows:
−
if installed the motorized filter wheels are turned to keep the color temperature constant.
−
If this will not do to completely match the calculated light-intensity levels, the intensity of the halogen
lamp is varied by changing the lamp voltage. That way, of course, the color temperature for object
observation changes as well.
−
The luminous-field diaphragm is adapted to the visual field of the eyepieces (see also Section 4.8.6.1
on page 119), the user, however, may readjust it individually.
−
The aperture diaphragm is adjusted according to the objective aperture (changes will be saved
separately for bright field and DIC).
−
If you want to reset temporary Light Manager
values to the last settings saved with the
LM-
Set
button, you can do this bay pressing the
User defined
button. On doing so, the
temporarily stored values are overwritten by the
permanently stored ones and activated.
−
If the manufacturer’s default settings are to be
used instead, the
Default
button must be
pressed. On doing so, the default values will be
loaded, written to the temporary memory and
activated. If you want to use the default settings
permanently, write them to the permanent
memory by pressing the
LM-Set
button. The
manufacturer defaults cannot be overwritten.
The calculated intensities apply only to the contrast technique selected. That means the
intensity must be adjusted specifically for each contrast technique.
The Light Manager works only if all dependent components were configured correctly (see
Section 4.8.6).
