Ossila Spectrometer Software Connecting a Device When the software starts, the user will be presented with the device connection box. Any Ossila spectrometer devices connected to the computer that are detected by the software will appear in the dropdown box. -
Page 14: Window Layout
User Manual Figure 9.2. Ossila Spectrometer software main window. Window Layout The Ossila Spectrometer software window is separated into areas indicated in Figure 9.2. The function of these areas are briefly outlined below. 9.2.1 Menu Bar Access various features related to device and software settings. - Page 15 • Get Reference - Take a reference spectrum. Note that a background spectrum must be • taken first. Note: The functions in the experiment menu are all available as buttons on the Quick Access Menu. www.ossila.com Ossila Limited © 2023...
- Page 16 When disabled, the workspace can be scrolled (if enough spectra are present in the workspace) so that previously recorded spectra can be check/unchecked while an acquisition is in progress.

Page 20: Measurement Modes
In both modes a specific axis can be controlled by using these controls on the axis labels. Measurement Modes The Ossila Spectrometer software can perform measurements in the following modes: (I) Intensity The raw output from the analogue-to-digital converter is displayed. This can take values between 0 and 65534. -
Page 21: Trigger Modes
(������������������������). A background and reference spectrum must be present to select this measurement mode. Trigger Modes The Ossila Spectrometer has three trigger modes that can be selected from the ‘Trigger’ dropdown box in the Measurement Settings. (I) Internal Trigger The start and end times of acquisitions are handled by the spectrometer. The time spent collecting a signal is determined by the integration time. -
Page 22: Calibration
40 µs. With the flush disabled this delay is reduced to 15 µs. Calibration The Ossila Optical Spectrometer is factory calibrated for wavelength. Over time, it may be necessary to recalibrate the system. This can be performed by the user. The factory calibration is permanently stored in the system memory, so any user calibration can be reverted to factory calibration if required. - Page 23 The pixel numbers and wavelengths do not need to be in ascending order; however, the data pairs must be monotonic (increasing pixel number results in increasing wavelength).

Page 26: Example: Taking An Absorption Spectrum
Next, set up the experiment. Absorption measurements require a sample to be placed in between a light source and the spectrometer. In this example we will use the Ossila Broadband White Light Source and the Ossila Spectroscopy Transmission Holder (both sold separately). However, any light source that emits over the range of the required absorption spectrum would be sufficient, and any method of fixing the sample between the light source and the spectrometer is acceptable. - Page 27 Next, carefully load the sample into position. The alignment of the apparatus must not change in between taking the reference spectrum and the data. If using optical fibres, do not rearrange their positions at this point. www.ossila.com Ossila Limited © 2023...
- Page 28 Figure 10.4. Note the data outside of the light source emission range (approximately 370 nm – 850 nm) appears extremely noisy. This is because you cannot calculate the absorption of light if there is no light to be absorbed, therefore this data should be discarded. Figure 10.4.

Page 29: Offset And Gain Adjustment
Figure 11.1. Dark spectra taken with 3 different offset values: 420 - offset too low, reduces the dynamic range of the device, 455 - offset too high, signal pushed below the detection range of the ADC and 440 – offset correctly set. www.ossila.com Ossila Limited © 2023... -
Page 30: Sources Of Noise
Spectrometer User Manual The offset and gain values can be adjusted from within the Ossila Spectrometer Software by opening the command window from the System menu in the toolbar. The <offset?> and <gain?> commands can be used to query the current offset, and the <offset:value> and <gain:value>... - Page 31 It can therefore be removed by subtracting a background signal. Figure 12.2 shows an uncorrected and background corrected dark signal at 5 s integration time. Figure 12.2.

(2) with background subtraction. It is good practice to use a background correction when performing sensitive measurements. Background and reference spectra should be remeasured if any of the acquisition settings are changed (i.e., integration time, accumulations or averaging). www.ossila.com Ossila Limited © 2023... -
Page 33: Command Library
User Manual 13. Command Library The Ossila Spectrometer communicates with a host computer through a serial command library. When connected to a PC, the system will appear as a COM port, to which the serial commands could be sent. This section describes the command protocol and lists the available commands. -
