Connecting and Acquiring Images

To connect to a spectrometer, click on the connect button. A popup will ask you to select the camera you will want to connect to. If you receive the error message that no camera has been found, check the IP settings of the camera if it is of GiGe type (see troubleshooting #8.1/).

Spectrum Analyzer is compatible with both the Starter and Performance Editions but also support any spectrometer for which a .dll library has been included to connect to. By default, the application will load almost any recent PtGrey monochrome cameras. So far, the program has been validated with the following camera models:

The first time you connect to the spectrometer you will get a notification that no calibration could be imported from the camera. In the absence of calibration, some options of the program are disabled and the axis will be restricted to Pixel type. You may still acquire and save spectra. When spectra are saved as Spectre files, you may later import a calibration to these files to re-enable the missing settings. Spectrometer calibration is discussed in more detail in section 6/. When connecting the camera for the first time, you may also get a warning message that the ROI is larger than the recommended value of 128 px and that it may slow down processing. Select the “yes” option. Consult section 7.1/ for tuning ROI.

To capture a spectrum, click on the single capture button:

You may also acquire images in live by clicking on the live capture button:

Live capture will usually be necessary when aligning the spectrometer. Some of the functionalities are disabled in the live capture mode. When exiting the live capture mode, the last spectra will be kept and you will be granted the same settings access as when using the single capture action.

It is also possible to capture a single image by pressing the F5 key on your keyboard.
