closed, but the
MWM
device-based controller will remain running if it was
enabled.
mogwave
must also be acquiring measurements for the
mogwave
PID
controller to work, but the main display interval does not affect actual
measurement speed and thus
PID
response.

Acquisition
Exposure
Sets the exposure time, in milliseconds. If the
Auto
button is pressed,
the software will attempt to find an optimum time. The maximum time is
currently 100 ms.
Interval
Defines a dead-time between measurements. Can be anything up to 15 s.
If the
Rec
box is checked, measurements are recorded in a tab-separated
file until the
Rec
is unchecked. A new file is created each time recording
is started. The filename is generated automatically based on the current
time.
Average
The displayed numerical wavelength is the average of the most recent
n
measurements, where
n
is the number in the
Average
field.
If the
Spec
box is checked, then instead
n
spectra are averaged, and the
wavelength calculated from the spectrum average.
Zoom
The 10x and 25x reduce the wavelength range, to show greater detail of
the peak and increase the measurement rate. The wavelength range is
determined automatically to be centred on the spectral peak.
The Log button changes the display to show 20 log
10
of of the measure-
ments, relative to 0 dB at the saturated pixel value.
