The simulated gas discharge spectrum is synthesized by assigning each emission line to a gaussian and each point in the spectra is computed as a mathematical sum of all the emission lines. Should be adjusted to 'burn out' the strongest lines and boost the intensity of …
Gas-discharge lamps are a family of artificial light sources that generate light by sending an electric discharge through an ionized gas, a plasma. Typically, such lamps use a noble gas (argon, neon, krypton, and xenon) or a mixture of these gases.
The graphs for the gas discharge lamps and for “broadband” tungsten light at two brightness settings (faint = cool lamp, bright = hot lamp) are shown on the following pages.
Below are images of the spectra of the lines of each element which would be observed as emission lines in an electrical gas discharge. The images are screen shots of an applet - originally written by John Talbot - which reads in a file with wavelengths and intensities and makes a colourful representation of the spectrum.
The simulated gas discharge spectrum is synthesized by assigning each emission line to a gaussian and each point in the spectra is computed as a mathematical sum of all the emission lines. Contrast: Range: 1 to 10000 (the upper limit comes from intensity of the weakest line)
• Observe the emission spectra of gases in discharge tubes. • Observe the light emitted by solutions of cations in a flame. • Obtain wavelength values from a calibration graph.
The spectra of a series of gas discharge sources were measured with a spec-tral radiometer from 350 to 2500 nm in 1 nm increments. The radiometer used was an ASD (Analytical Spectral Devices). This instrument was also cross-calibrated, in some cases, with a spectraphotometer (Photo Research PR650). Two high-pressure sodium lamps were measured.
Jun 1, 2004 · The physics of gas discharge lamps is reviewed, with particular emphasis on new developments in the field. In addition to the most important light sources (fluorescent and high-pressure ...
