Development of a Laser Raman Spectrometer for Deep-Ocean Science
We have extensively modified and successfully used a laser Raman spectrometer (DORISS, Deep-Ocean Raman In Situ Spectrometer) for geochemical studies in the deep ocean. The initial instrument from Kaiser Optical, was separated into 3 components: an optical head, a laser-power supply-telemetry unit, and the spectrometer. These components were modified to fit into custom designed pressure housing...
متن کاملA Low Cost LED Based Spectrometer
A low cost LED based spectrometer is described. This LED based spectrometer could be operated as a standalone instrument or under PC control via serial link. A total of seven wavelength selections are available by the plug-and-measure LED light module. With the seven wavelength selections, the LED based spectrometer could provide qualitative visible absorption spectra that predict the absorptio...
متن کاملX-ray spectrometer with a low-cost SiC photodiode
A low-cost Commercial-Off-The-Shelf (COTS) 4H-SiC 0.06 mm2 UV p-n photodiode was coupled to a low-noise charge-sensitive preamplifier and used as photon counting X-ray spectrometer. The photodiode/spectrometer was investigated at X-ray energies from 4.95 keV to 21.17 keV: a Mo cathode X-ray tube was used to fluoresce eight high-purity metal foils to produce characteristic X-ray emission lines w...

متن کاملA Cooler Raman Laser
P ower dissipation, which results in heat generation in electronic chips, is the number one difficulty facing the semiconductor industry. The problem is so severe that it threatens to halt the huge development that has been enjoyed since the microprocessor industry’s inception — a doubling in processor performance roughly every 18 months, which was predicted by the celebrated Moore’s law. And t...
