Laser Induced Breakdown Spectroscopy
is a form of atomic emission spectroscopy which is typically performed using a pulsed laser to create a surface ablation on a sample which is then analyzed spectroscopically for its elemental and molecular composition.

Laser Induced Breakdown Spectroscopy
. Laser Induced Breakdown Spectroscopy or LIBS has become the common acronym for element detection via laser induced plasma. This permits real-time qualitative identification of trace elements in solids, gases, and liquids via optical detection of elemental emission spectra. Using this technique, little or no sample preparation is required and calibration-free quantitative analysis has been reported without matrix effects.

Atomic Fluorescence Spectroscopy explained
. When the energy required to excite an electron is the same energy as the photon it gives off when it returns to its ground state, it is called resonance fluorescence, and is easily detectable using AFS. The J505 instrument uses a mercury lamp to excite the mercury atoms at the 254nm wavelength, and then uses a detector to measure the emission of the photons, at the same wavelength, as the electrons return to their stable ground states. Because AFS measures the emission of photons... (read more)

IR Filters-NIR , MWIR, and LWIR
Cascade Optical Corporation has been making IR filters for over 25 years. We work with NIR , MWIR, and LWIR. We also have the distinct advantage of manufacturing Exotic substrate material suitable for each band. NIR 0.8 -1.8 μm --applications can range anywhere from Telecommunications and Spectroscopy to Night Vision. Where, MWIR 3 -5 μm is typically used on heat seeking missiles where the jet engine photon emission is the greatest. And, LWIR 8 -12 is often used for thermal imaging... (read more)

Using emission spectroscopy to perform impurity analyses in UHP gases
, but of equal importance was the use of a new technique: emission spectroscopy. When excited in an electric discharge, the gases dissipated some of the energy as electromagnetic radiation at wavelengths that were specific to each gas. The spectral lines were intense enough to be easily observable
OH Emission Spectra of Hybrid Rocket Motors Using

vibrations specified in wave numbers (1/cm) where: Wavelength (in micrometers) = 10,000 / wave numbers. Raman scattering is a very weak effect. The strength of the Raman emission is typically a million times less than the strength of the illuminating beam. Thus measuring the Raman-scattered radiation
