Green Photonics Raman Spectroscopy

When most people hear the phrase “green photonics” they immediately think of green laser pointers.  However, green photonics is more than just laser beams with wavelengths between 500 and 550 nm. The threat to our energy supply posed by the exhaustion of fossil fuels requires renewed innovation in the development of technologies that can sustain…

High Performance Raman Spectroscopy

Raman spectroscopy allows for the detection and identification of molecules through their unique vibrational and rotational energy level structure. As opposed to fluorescence methods, which require the addition of a separate fluorescing molecule as a “tag” attached to the actual molecule of interest, Raman spectroscopy allows direct detection of a molecule with no chemical alteration.…

UV Imaging

Many biological molecules of interest naturally fluoresce when excited by shorter- wavelength UV light. This intrinsic fluorescence can be a powerful tool. One important application is the direct fluorescence imaging of aromatic amino acids including tryptophan, tyrosine, and phenylalanine, which are building blocks for proteins. The aromatic rings in these molecules exhibit strong fluorescence excitation…
