2.3. Using Multiple Spectrometers#
TII Spectrometry supports the simultaneous control of multiple supported spectrometers . This can be useful in the following scenarios:
to combine spectrometers monitoring a single source with adjacent spectral ranges to expand spectral coverage. This used in the application example ‘The Solar Spectrum’
to use multiple spectrometers (with identical or different spectral coverage) to monitor several processes simultaneously
Fig. 2.20 Using multiple spectrometers in TII Spectrometry#
Examples for these applications are displayed in Figure 2.20. There are no limitations on the number or type of spectrometers that can be controlled simultaneously in TII Spectrometry.

2.3.1. Device Manager#
Fig. 2.21 The Device Manager#
To connect to multiple spectrometers, use the Device Manager (Figure 2.21), which can be accessed using . The Device Manager window will display all supported and connected devices. To connect:
enable the checkbox for the devices you would like to connect to
click OK

See Section 2.2.2.1 for details on remote connections to ARCoptix devices.
2.3.2. Use & Display Options#
Connected devices will be displayed on the top bar of the main window. Here:
you can set the exposure time and averaging number for each device device individually
use the checkbox to activate or (temporarily) deactivate one or more devices.
Two display options are available:
the Combined view. Here, spectra from different devices are combined and displayed on the same spectral axis. This is useful when using multiple spectrometers to expand spectral coverage.
the Split view. Spectra are displayed in separated graphs.

Figure 2.20 shows examples for these two display modes.
The menu gives access to Time-lapse Recordings, which allows software-synchronized time-lapse acquisitions using multiple spectrometers. In the Time-Lapse window, you can switch between Combined and Split display using the menu.
The menu gives access to spectrometer settings for each connected device, e.g Intensity Calibration
the spectrometer menu now contains the command. This allows adjusting the wavelength range covered by each spectrometer by setting a switchover wavelength, i.e. the wavelength at which switching from one to the next spectrometer occurs (see Figure 2.22 for an example)

recordings using multiple spectrometers can be processed, saved, and loaded from disk just like regular, single-device spectra.
multi-spectrometer configurations can be saved and reloaded.
