Chapter 5 LightField First Light Procedure 45
The
Experiment Settings
stack to the left now displays several expanders. Because
this is a new experiment, the default settings for the detector are active.
The
Status
bar at the bottom of the window displays an icon for temperature status
which reports the current temperature and whether the set temperature has been
reached. Clicking on the icon opens the
Sensor
expander where the set temperature can
be changed.
3.
From the
Shutter
expander, select
Shutter Mode: Normal
.
5.4 Confirm System Setup
Perform the following procedure to confirm proper system setup and configuration:
1.
Turn on the light source at the spectrograph entrance slit.
2.
Click
Run
to begin previewing data. Depending on the display settings, either a spectral
band (i.e., image,) or a graph should be displayed. Background noise will decrease as
the camera cools to its default temperature.
3.
Turn off the light source.
Does the displayed data change to a background noise pattern or low intensity graph?
• YES
Light entering the spectrograph is being seen by the camera. The system may now
be aligned and focused. Proceed to
Section 5.5, Rotational Alignment , on page 46.
• NO
There is no difference between data displayed when the light source is on or off.
Proceed to step 4.
4.
Verify that the light source has power and is turned on.
5.
Verify that the entrance slit is open a minimum of 10 µm.
6.
Verify the
Exposure Time
on the
Common Acquisition Settings
expander is as
required.
7.
Confirm that
Shutter Mode
is set to
Normal
on the
Shutter
expander. If it is not,
change it to
Normal
.
8.
Check the shutter cable connections.
9.
Can the shutter be heard opening and closing while operating in
Run
mode?
• YES
Turn the light source on, wait a minute, and turn the light off while viewing the data
display.
Is the issue resolved?
— YES
Stop acquisition and proceed to Section 5.5, Rotational Alignment , on page 46.
— NO
Stop data acquisition and proceed to step 10.
• NO
Stop data acquisition and proceed to step 10.
