86 WinView/32 Manual Version 2.4.M
If using an intensified camera, note that data collection in the following procedure will
be done in the CW/Shutter mode, in which light overload can easily occur. Before
powering the controller and camera, reduce the room light to reduce the risk of overload
damage. Note that intensifiers are particularly at risk in pulsed laser operation, where
overload spot damage can occur without raising the average current to where the
overload detection circuits will be activated. It is far better to be careful than sorry.
Before proceeding, take the time to carefully read the manual for your intensified
camera.
Also, take particular care that your intensified camera is connected properly for shutter-
mode operation. Cabling and peripheral considerations for intensified cameras are more
complex than for unintensified cameras. Again, read your camera manual.
Temperature Control
Before continuing, the array temperature should be set to some easily achieved value in
the operating range and Temperature lock should be established. The way this is done
depends on the controller. With an ST-121, ST-130 or ST-138, the temperature is set by
means of a dial on the front panel of the Controller. In the PentaMAX it is set from the
front panel of the Power Supply. In the case of MicroVIEW, the temperature is solely
under software control and can not be set by the user. With the MicroMAX, ST-133 or
V/ICCD (or V/ICCD Control Box) the temperature is set via software. To set the
temperature with one of these controllers, open the WinView/32 Setup menu and click
on Detector Temperature. This will cause the Temperature dialog box to appear as
shown in Figure 66. Then set the
Target Temperature
to the desired value (0°
suggested for initial data acquisition) and click the SET button. When the
Current
Temperature: Unlocked
message changes to
Current Temperature: Locked
,
temperature lock will have been established. Note that both the MicroMAX and the ST-
133 additionally have a
Temp Lock
LED on the panel of the Analog/Control module
that visually indicates when temperature lock occurs. In the case of the V/ICCD or
V/ICCD Control Box, you can also set the temperature from the
Video Focus
dialog
box.
Skips & Cleans
With some controllers, specifically the PentaMAX, ST-130, ST-133 and ST-138, there is
a Cleans/Skips tab page in the Hardware Setup window. For the procedures that follow,
load the default values for these parameters by bringing the Cleans/Skips tab page to the
front, and then clicking on
Load Defaults
followed by
Yes
.
Exception:
With an PI-
MAX camera, set Cleans to 1 and Strips per Clean to 4.
