- Measurement vs. Concentration—conduct a Beer's law experiment.
- Measurement vs. Time—collect time-based data for a kinetics experiment.
By default, Absorbance is expanded. You can also choose from % Transmittance, Fluorescence, Emissions, or Advanced Full Spectrum. Use the Advanced Full Spectrum mode to switch between all the measurement types in the same session. For complete instructions, refer to the Spectral Analysis user manual at www.vernier.com/spectral-analysis
Measurement vs. Wavelength (Full Spectrum)
- Select Measurement vs. Wavelength.

If using Fluorescence, Intensity, or Advanced Experiment modes, you can modify this value to increase the amount of light hitting the detector and the signal spectral output.
- Wavelength Smoothing: This is the number of adjacent readings on either side of a given value that is used to calculate an average value.
- Temporal Averaging: This is the number of readings taken at a given wavelength to calculate an average reading.
- Select the Calibrate button to recalibrate your spectrometer at any time.
Measure an Emission Spectrum with Spectral Analysis
You may use your Spectrophotometer to measure the emission spectrum of a light source such as an LED or a gas discharge tube. To do so, you will need to purchase the Vernier Optical Fiber (order code: VSP-FIBER).
Measure Intensity of Light Emissions
Insert the Vernier Optical Fiber into the SpectroVis Plus.
- Connect the sensor following the steps in the Getting Started section of this user manual.
- Open Spectral Analysis.
- 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 Spectrophotometer is not calibrated for measuring intensity.
- Aim the tip of the optical fiber at a light source. Start data collection. 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).
To adjust the integration time, click or tap the gear. Set the integration time to a suitable value.
Measure Fluorescence with Spectral Analysis
You may use your Spectrophotometer to measure the fluorescence spectrum of an aqueous sample, such as chlorophyll, riboflavin, and fluorescein. Fluorescence is the emission of light by a compound after it has absorbed a particular wavelength of light. Under most circumstances, the emission of light will occur at a longer wavelength than the light used to excite it. The SpectroVis Plus has two excitation wavelengths: one at 405 nm and one at 500 nm.
There are three general types of data collection that measure fluorescence— fluorescence vs. wavelength, which produces a spectrum, fluorescence vs. concentration, and fluorescence vs. time for kinetics experiments. To collect these types of data after the experiment type has been selected as Fluorescence, follow the instructions in the Spectral Analysis user manual at www.vernier.com/spectral-analysis. Note: You may need to change the integration time to get accurate peak intensities in fluorescence mode. To adjust the integration time click or tap on the gear. Set the integration time to a suitable value.
