Page 6: Setup Instructions
Setup Instructions 1. SpectraWiz Installation Load your CD or USB drive and install the SpectraWiz Software. Different versions of SpectraWiz are available and are stored in separate folders according to your computer’s operating system. Choose the “SETUP” application from the appropriate folder. For Windows XP, select D:\SpectraWiz for Win 2k-NT-XP Ver 4.1, SETUP. - Page 7 4. SpectraWiz Setup Run the SpectraWiz software. The dialogue box below, “SpectraWiz Spectro Hardware Setup“, will appear. The correct detector type is “CCD 2048” and the “USB2EPP cable” option should also be checked. These are the only two options you should have selected. Exit Setup. Click on the setup menu and select Unit Calibration Coefficients.

Page 8: Usb2 Cable Installation
USB2 Cable Installation 1. Disconnect the internet connection to your PC (Do not allow windows to connect to Windows Up- date). 2. Power the spectroradiometer. 3. Connect the USB2 cable to the spectroradiometer and one of the USB ports on your PC. This will prompt the following wizard: 4. - Page 9 The First Two Steps For Every Measurement 1. Set Detector Integration Time The detector integration time is like the shutter speed on a camera. It controls the amount of light reaching the detector. An integration time that is too high exposes the detector beyond its range and saturates the readings you will view.

Page 10: Integration Time
Integration Time About the Integration Time The current integration time is displayed on the status bar at the bottom of the screen (e.g. Time: 100ms). This is the amount of time (in milliseconds) that the spectroradiometer records for a single measurement. -

files for the Spectroradiometer you will not be using to swUV.ini and sw1UV.icf. Apogee suggests making separate folders (e.g. NIR Cal Files and UV Cal Files) inside the SpectraWiz folder to help to keep them separate. Change the names of the files but not the exten- sion. -
Page 15: Spectral Modes And Applications
Spectral Modes And Applications Reflectance, Transmittance, And Absorbance Measurements Reflectance and transmittance are measured as percent of the incident incoming radiation and are both measured using transmission mode: View Transmission. Absorbance is a measure of optical density and is measured using absorbance mode: View Absorbance. - Page 16 Overlaying Multiple Spectra To overlay multiple saved spectral traces: Open and navigate to the files folder. hold down the shift key (for contiguous files) or the control key (for noncontiguous files) to select multiple files before clicking “open.” Each spectral trace is graphed in a different color. Excel is capable of importing files created by SpectraWiz.
- Page 17 Applications The Apps menu allows color monitoring, solution concentration predictions, and irradiance and wavelength calibration. Cielab This CIELAB application performs color measurement using the International Commission on Illumination (CIE) techniques. The application provides a chromaticity diagram for irradiance and a spectrocolorimeter function for reflectance.
- Page 18 (see page 9). For the best results using a reflectance probe, use a fixture that holds the tip at the same distance from each sample. Apogee carries such a probe with a built in light source.

Page 19: Detailed Control Bar Descriptions
Detailed Control Bar Descriptions Move Data Cursor / Seek Peek When you click on either button, a vertical line appears on the graph of your spectrum. At the bottom of the screen, the intensity of the spectrum and the wavelength of the vertical line are reported. The line can be moved to the right or the left by clicking on these buttons. - Page 20 X Zoom Info / Y Zoom Enable Zooms out to fit the entire wavelength range supported by the spectrometer in use. Holding down the left mouse button and dragging between the wavelengths of interest will zoom in. This function also fits the y-scale to the visible spectral trace.

System Indicators The system indicators are displayed in the status panel at the bottom of your screen. From left to right, the system indicators are as follows: View Mode (SCOPE->) controlled under the ‘View’ menu Wavelength (Wave: 541.1 nm) – controlled by peak right and peak left icons Pixel number (Pix: 553) Y-value at the specified wavelength (Val: 680.053) Integration time (Time: 500 ms) –... -
Page 22: Menu Descriptions
Menu Descriptions The File menu contains the save, Export, open, print setup, print, and exit commands. • Detector Integration Time: may be adjusted manually to allow more precise integration time adjustments than the slide bar. • Number of Scans: SpectraWiz automatically averages a user-defined number of scans for each reading. - Page 23 This allows a visual estimate of variance in a sample over time. Graph trace as 1st derivative or 2nd derivative allows the examination of spectral derivatives, which are used in many studies to remove background from spectral applications. techsupport@apogee-inst.com...
