Acquisition of Upgrades for Raman Spectroscope for Enhanced Speed, UV and Polarization Capabilities
Abstract
The goal of this proposal was to acquire upgrades such as ultrafast Raman spectrometer (ANDOR Newton EMCCD from Raman in Via)with polarization and UV Raman spectroscopic capabilities for characterizing the deformation behavior of ultra hard ceramics (e.g., SiC,B4C, and B6O) used for body- and vehicular-armor. In particular, the system is used for mapping the a morphization zones and residual stresses within boron-rich solids as well as to analyze the compositional variations in ceramic composites. The PI has upgraded the current Raman microscope system with a high-speed encoded stage (HSES), polarization optics and lenses for an ultraviolet laser, an Andor EMCCD camera, a dual-wavelength 325 nm (UV) and 442 nm He-Cd laser, a dual-wavelength laser power supply, an upgraded video camera for optical microscopy, and an enclosure for safety purposes. Several graduate and undergraduate students who are currently working on Army-funded projects have been trained in the proper use of this instrument. Preliminary results on B6O have demonstrated an improved spectral signature in response to excitation from the new UV laser as opposed to its response to the 532 nm visible laser. The total cost of the equipment was $184,184.00.
