Connected
LED next to USB icon is solid green.
Using the Spectrometer with Spectral Analysis
You may use your spectrometer to measure the emission spectrum of a light
source such as an LED or a gas discharge tube. To do so, you may wish to
purchase an optical fiber assembly (www.vernier.com/vsp-em-fiber) though this is
not required.
Connect the sensor following the steps in the Getting Started section of this user
manual.
Measure Intensity of Light Emissions
Connect the Optical Fiber to the spectrometer (optional). Intensity is reported in
relative units with a range of 0–1.
Note:
The spectrometer is not calibrated for
measuring absolute intensity.
1. Launch Spectral Analysis.
2. Connect the spectrometer following the steps in the Getting Started section of
this user manual.
3. Select the appropriate Emissions experiment from the listed options and follow
the prompts in the app. Intensity is a relative measure with a range of 0–1.
Note:
The Spectrometer is not calibrated for measuring intensity.
4. Aim the tip of the optical fiber at a light source. Start data collection. Click or
tap the Stop button to end data collection.
If the spectrum maxes out (flat and wide peaks at a value of 1), increase the
distance between the light source and the tip of the optical fiber cable or reduce
the integration time (see the Change the Settings in Spectral Analysis section).
