Tip-Enhanced Raman Spectroscopy
TERS - Tip-Enhanced Raman spectroscopy

Laser-Induced Breakdown Spectroscopy
LIBS is considered one of the most convenient and efficient analytical techniques for trace elemental analysis in gases, solids, and liquids. LIBS spectra obtained by the Mars Curiosity Rover have confirmed that our sister planet could have harbored life

Absorbance, Reflectance and Transmission
A measure of the amount of light absorbed by a sample as a beam of light passes through it.

Fluorescence, Phosphorescence, and Photoluminescence Spectroscopy
Fluorescence, phosphorescence and photoluminescence occur when a sample is excited by absorbing photons and then emits them with a decay time that is characteristic of the sample environment.

General Raman
The most common application of Raman spectroscopy involves the vibrational energy levels of a molecule. Incident laser light in the UV, visible or NIR, is scattered from molecular vibrational modes.

Plasma Emission Spectroscopy
The different types of plasma emission spectroscopy can be categorized by how the plasma is generated. Spectra of nuclear fusion plasmas are used to ascertain the chemical species present and other properties.

Application Notes

Cherenkov Emission Imaging and Spectroscopy Using a Pulsed Linear Accelerator and the Subsequent Deep-Tissue Imaging of Molecular Oxygen Sensors in a Human Body Phantom
In 2012, a research group at Dartmouth College and Dartmouth-Hitchcock Medical Center led by Dr. Brian Pogue published results from their investigation into fluorescence and absorption spectroscopy methods using pulsed LINAC-induced CES2,5 under ambient room lighting conditions. This application note provides an overview of both that work as well as more recent experiments in which Dr. Pogue and his associates utilized Cherenkov radiation to perform high-resolution luminescence imaging of molecular oxygen sensors located at tissue depthsup to 3 cm.
