Configuration mode 2 for OPMI Vario (SETTINGS 2)
Configuration mode 2 for the OPMI Vario permits you:
– to set the adjustment speeds of focus and X-Y coupling as a function
of the zoom setting, menu item "SPEED FUNCT:"
– to set the lamp brightness as a function of the zoom setting,
menu item "LIGHT FUNCT:"
– to define the power-on behavior of the system,
menu item "POW ON MODE"
Setting the adjustment speeds of focus and X-Y coupling as a function of
the zoom setting (OPMI Vario)
Menu item "SPEED FUNCT:" permits you to select dynamic speed control
for the X-Y coupling and focus.
The depth of field of the optical system changes according to the zoom
setting:
– The depth of field is large for a large field of view (small zoom value),
and the focus needs to be adjusted over a large range for focusing the
image. This means that the XY-coupling must be adjusted over a large
range until the required position is reached. A high adjustment speed
should therefore be used in this case.
– The depth of field is small for a small field of view (high zoom value),
and the focus needs to be precisely adjusted in a small range for fo-
cusing the image. This means that the X-Y coupling must be precisely
adjusted within a small range until the required position is reached. A
low adjustment speed should therefore be used in this case.
It is therefore advisable to vary the adjustment speeds of the focus and
X-Y coupling in accordance with the zoom setting.
The instrument has been factory-adjusted for MEDIUM variation of the
adjustment speed as a function of the zoom setting. The best effect of dy-
namic speed control is achieved if an adjustment speed of <4.0 has been
selected in the speed mode.
Path: The basic mode is automatically displayed after the instrument has
been switched on.
To access configuration mode 2 from the basic mode, go via con-
figuration mode 1.
For this, simultaneously press the "MODE" and "STORE" keys
twice in succession:
1. Jump from the basic mode to configuration mode 1
2. Jump from configuration mode 1 to configuration mode 2.
