Fluorescent light spectrograms
WebFluorescent lamps work by ionizing mercury vapor in a glass tube. This causes electrons in the gas to emit photons at UV frequencies. The UV light is converted into standard visible light using a phosphor coating on the … WebThis methodology was tested on fluorescent lamps, white LED torch light, 100W Incandescent lamp and noon solar spectrum. The resulting spectrograms of the test light source were in close agreement with the respective theoretical references. Camera spectrometer is auto-calibrated and the need for a standard source during calibration is …
