StellarLab
StellarNet Spectroscopy Lab Experiments
Turn light into a hands-on learning experience with StellarLab. Designed for educational laboratories, these ready-to-use experiments help students explore spectroscopy and radiometry through practical measurement, analysis, and real-world applications.
SpectroChemistry
Lab #1: Quantification of Food Dyes in Sports Drinks
How much food dye is present in sports drinks? This is the question you will answer in this laboratory experiment.
Lab #2: Spectrophotometric determination of the % cranberry juice in cranberry-apple juice
What percentage of cranberry juice is present in different cranberry-apple juice brands? As in the previous experiment, you will use visible spectroscopy to answer this question.
Lab #3: Fluorescence of riboflavin in energy drinks
How much riboflavin (vitamin B2 ) is present in energy drinks? You will use fluorescence spectroscopy to determine the concentration of a riboflavin both Rockstar and an energy drink of your choice.
Lab #4: Exploring Chemical Bonding Using Raman Spectroscopy
Now you will learn about another spectroscopic technique: Raman spectroscopy. You will use a combination of computer simulations and Raman spectroscopy to study chemical bonding.
Lab #5: Detecting art forgeries using Raman spectroscopy
You will use Raman spectroscopy to determine the validity of two paintings – one painting is a forgery and one is genuine.
Radiometery
Lab #6: Light Source Spectra and Irradiance Distribution (NEW LAB!)
In this lab, a fiber-coupled spectrometer will be used to measure the spectrum of various broadband light sources.
Lab #7: Optical Emission Spectroscopy (NEW LAB!)
Investigate the emission spectrum of a gas discharge source using a diffraction grating, lasers of known wavelengths, and a spectrometer.
