Spectroscopic Sources Homework Problem Set
This problem set was developed by S.E. Van Bramer for Chemistry 366 at Widener University.
to introduce students to several common light sources
- Students will be able to identify the type of lamp used in a spectrometer
- Students will be able to describe the tradeoffs involved in lamp selection
Newport Optical has lots of technical information on sources available on the web at:
www.newport.com. In particular see:
Additional information for the instrumentation at Widener is available in the shared files for campus cruiser.
- Look at the information from Newport Optical and compare the wavelength range and intensity for deuterium, quartz halogen, and Xe arc lamps.
- Which lamp would you select to use for a scanning UV/VIS instrument. Why?
- What type of lamp is used for the ocean optics spectrometer? Why?
- What type of lamp is used for the HP UV/VIS spectrometer? Why?
- What type of lamp is used for the spectrovision fluorescence spectrometer? Why?
- Find the table in your textbook that summarizes the different sources and their wavelength range
