Software Features
Acquisition Modes
Live Acquire : This is a continuous (free run) acquisition mode. The
spectra are collected as rapidly as permissible by the spectrometer. For
continuous or transient monitoring, this acquisition method is
recommended.
Snap : This mode enables software triggered single shot spectrum
acquisition. The spectrum is collected only once. For single shot
evaluation of your sample, this method is recommended.
HW trigger Snap: This enables HW triggered acquisition mode. The
spectrum is collected only once when the switch on top of the
spectrometer is clicked. For single shot evaluation of your samples, this
method is recommended.
Spectrometer Controls :
Integration Time Sets the integration time, the time over which the
detector captures incident light. At the end of the
integration time the accumulated signal is read from the
detector by the electronics. Minimum is 10 us. Maximum
is 1s.
Gain Sets the gain on the device to capture low level light
signals. Use only in case of low light. High gain can lead
to nonlinear spectral/intensity inaccuracies. Maximum
setting allowed is 18.
Averages Signal, especially at low levels, is significantly impacted
by noise. Averaging several spectra together reduces the
impact of noise and improves the accuracy of the result.
Maximum averages are limited to 100. Use higher
integration times to record low light spectra. Please note
that, at long integration times, averaging can increase
the total time of a measurement significantly.
