Fig. 24.7: Dialogue window CCD Settings
The wavelength, attenuation, and operating mode are all set in the
CCD Settings
dialog window.
Trigger modes
The appropriate settings must be configured here in keeping with the operating mode of the laser to be mea-
sured. Here it is important to consider that pulsed lasers with a pulse frequency of more than 500 Hz can be
measured in cw mode. If, however, the operating mode is set to pulsed and a cw laser system is involved,
the measuring device will always display the error message “Error Black Pixel Measurement” or “Time Out
During Measurement” in reaction to a measurement request.
Delay
This function can only be used with a “triggered operation” trigger mode. The time the measuring system
should wait between when it detects the trigger pulse and the start of the measurement is set here. Together
with the function “Integration Duration”, defined “Windows” from the plus cycles can be measured (e.g. ex-
actly one pulse or parts of an ms pulse. The minimum delay is 12 µs.
CCD operating modes
Three different modes can be set here. If the
Raw Data
setting is activated, the measuring system will return
the uncompensated data of the CCD when a measurement is requested. Especially with NIR irradiation,
these can be riddled with measuring errors such as “smear effect” readout noise. Even the numeric beam
data generated from this data will be affected by this.
If a
Background
is selected as the operating mode, only correction data will be returned while measuring.
Measuring Data
mode should always be the default setting here though. Only when this mode is turned on
can the measuring system deliver reliable measuring values.
