Operating the DLP NIRscan EVM
Figure 3-3. Example Quick Scan Spectrum Data
Note that the header in the download file contains many important aspects of the scan, including:
1. Method: This defaults to linescan mode at this time, referencing how the sample is taken by scanning
vertical lines across the DMD, each line representing a specific wavelength.
2. Host Date-Time: This is the date (browser date) and time the scan was taken.
3. Sample name: this is the scan name entered on the first Quick Scan screen. If the scan name has not
been changed, the sample name defaults to default_scan.
4. Spectral Range Start: always 1350 nm for Quick Scan mode
5. Spectral Range Stop: always 2450 nm for Quick Scan mode
6. Number of wavelength points: 200 for Quick Scan mode
7. Digital resolution: 5.5 nm for Quick Scan mode
8. Number of scans to average: 1 scan for Quick Scan mode
9. Total measurement time: The time taken to scan all wavelengths
10. The rest of the file is the actual data and includes:
• Wavelength
• Calculated spectrum value for each wavelength
• Average reference ADC value for each wavelength
• Average sample ADC value for each wavelength
After the data is saved locally on the machine running the browser, the user can return to the Quick Scan
screen.
