Why Deep UV Spectroscopy?
Deep UV excited Raman & photoluminescence spectroscopy is an emerging
analytical instrument technology with vast potential for a wide range ofcommercial, industrial, and research applications. A major limitation of Raman
spectroscopy conducted in the near UV, visible, or near IR is obscuration orinterference of the Raman signals due to background fluorescence from theanalyte or its background or surroundings within the laser beam interrogation
spot. This interference limits the types of materials and compositions orbackgrounds for which Raman spectroscopy is useful.
Autofluorescence is a phenomenon which does not occur below about 270 nm
for the vast majority of materials, independent of excitation wavelength.
Raman, on the other hand, is dependent on excitation wavelength and whenexcitation occurs below 250 nm, there exists a spectral region within which toobserve over 3000 cm-1 of Raman shifted emissions without obscuration orinterference from fluorescence.
This is the driving motivation for spectroscopy conducted in the deep UV withexcitation below 250 nm. Also, operation in the deep UV enables simultaneous
detection of Raman and fluorescence spectra, enabling the much higher
sensitivity of fluorescence and the higher specificity of Raman spectra. There
are many other advantages of operation in the deep UV including enhanced
Raman signal strength due to resonance effects, simplification of Raman
spectra for resonant materials making spectra easier to interpret, small depthof penetration into many materials, which limits interference with backgroundor substrate materials, and other benefits.
Deep UV resonance Raman & photoluminescence spectroscopy has beenhampered by the lack of a suitable laser source in the deep UV. Photon
Systems has developed a new enabling laser technology to address thisproblem. These lasers have exceptionally narrow and stable emission
linewidths and are hundreds of times smaller, lighter, and lower power
consumption that other deep UV lasers. Photon Systems lasers have beenvetted in a wide range of harsh commercial, industrial and research
applications and have been selected by NASA for the Mars 2020 lander missionfor a rover arm mounted deep UV Raman and fluorescence instrument.
The DUV Raman PL 200 is available in three configurations:
H1 Basic Instrument includes a standard XYZ manual translation stage andcontext camera.
H2 Scan Instrument includes a motorized XY with manual Z stage with mapping
function and context camera.
H3 Liquids Instrument includes a cuvette holder for liquids analysis.
