Laser Monitoring – SpectraWiz Quick Start

Turn on the computer. Open the StellarNet software by double clicking on the desktop icon SpectraWiz to open the application.
When you first open the software, you should see a screen similar to the one below:
Shoot your laser into a entrance diffuser such as the CR1-UVN and couple to your spectrometer.
In SCOPE mode you will see you laser’s spectral profile and be able to use our peak tool icon to calculate AreaPSD, Centroid, Peakwave, FWHM, and Centbase of a peak.
Set the integration time so that your spectrum, in the SCOPE mode, is not saturated but as close to 65,000 counts as possible. Click on the integration time icon (and type in a value between 1 and 1000 ms) or use sliding scale . In the first picture below, the spectrum is correctly optimized to be right below the saturation limit (65,536 counts). If a portion of the spectrum is off the screen reduce the integration time. If you have a high power laser it is advised to use more entrance diffusers and a small detector exposure time and slowly remove diffusers and increase your detector exposure time. The goal is to maximize your signal in SCOPE mode. You want to adjust your integration time until the spectrum fills most of the SCOPE graph (65,000) without saturating.
This is also the time at which you should adjust the number of scans to average (more scans averaged will increase accuracy, but will take more time for each reading). You can also add smoothing controls at the time too in the setup tab.
