All VisiLED illuminations can be controlled in segments using the MC 1500.
By choosing the optimal segment mode for each specimen an object
contrasting can be achieved which far exceeds the contrasts one gets using
a non-segmented ringlight.
Repeated activation of the select key (3) changes the segment mode of the
selected illumination unit (A or B):
„Full circle Semi circle Quarter circle
➔ ➔

The LED indicators of the segment control (2) display in which segment mode
the selected unit is currently set.
To change or check the segment mode of the second VisiLED unit this must first
be selected using the unit selector key (1).
If the MC 1500 is being controlled via a computer then all 8 individual segments
of each illumination unit can be accessed. By combining the individual segments
user-defined segment modes can be set.
The MC 1500 makes it possible to set the brightness of all VisiLED illumi-nations.
