Optical Spectroscopy (UV/vis) Flashcards
Learn Components, and their uses
1
Q
Instruments
A
Light source, wavelength selector, sample, light detector
2
Q
Light sources
A
Continuum sources, line sources. Source must be reliable (output stable) and powerful. Examples: tungsten lamp or deuterium lamp
3
Q
Wavelength Selectors
A
Prisms (old), diffraction grating (modern method). To increase the spectral range covered consider having multiple gratings
4
Q
Photon Detectors
A
Phototube
5
Q
Sample
A
Single beam or double beam. The schemes of these are to be known, draw on nearest piece of paper and compare with notes
