Take a CD and a cereal box, and what do you have? With a little help from Mark Tiele Westra, your very own spectrometer! Time to explore the
To build and calibrate a simple box spectroscope capable of measuring wavelengths of visible light. To use this spectroscope to observe and measure the line spectra
Ion microprobes, also known as secondary ion mass spectrometers (SIMS), use a finely focused ion beam to probe a selected sample domain.
In this activity, you will go deeper to explore the science and engineering of spectroscopy—the study of the spectrum and what it tells us about our world and the universe. In 1665, Isaac Newton
Most modern Mass Spectrometers now employ a dual detector system. These detectors are a Faraday cup and a Secondary electron multiplier.
Secondary ion mass spectrometer. The glove box allows sample introduction into the main chamber without radiation exposure of the SIMS operator.
Constructing a cereal-box spectrograph We can make good use of these household diffraction gratings for constructing our own spectrometer. It consists of two important elements: a CD, which separates
