A laboratory spectrometer is a device used to measure the intensity of light as a function of the color of light.
Brimrose's core Acousto-Optic Tunable Filter (AOTF) technology is being used in the spectrometer. Using AOTF, an RF signal is applied to a TeO2 crystal, producing acoustic waves within the crystal.
The final implemented hyperspectral imaging spectrometer can provide an instantaneous FOV of 0.22 mrad in 6.57 degrees and a spectral sampling of 1.6 nm and covers the range of 450 to 850 nm.
"The spectrometer would be especially useful in clinics and hospitals that have a large number of samples without on-site labs, or for doctors who practice abroad or in remote areas," he said.
A particular claim for the work was that the CQD spectrometer is advantageous over interferometric techniques because of photon efficiency, resolution, and spectral range.
1st Detect Corporation was formed to develop and commercialize miniature mass spectrometer technology first developed under an agreement with NASA for use on the International Space Station.
According to the reader survey, issues researchers have identified with existing spectrometers include the high cost of repairs and maintenance of older systems (38% of respondents), out-dated systems lacking the characteristics and amenities of new systems (24%), availability and cost of service for older systems (20%) and the reliability of these older systems as well (20%).
--an optical channel which comprises a digital laser telemeter connected to the portable computer- meant to measure and fix the required distance between radiation source and video spectrometer as well as to centre the optical axis of spectrometer on the source of spectral radiation using the targeting of maximum emission area with red beam of laser radiation

Scientists will use data captured by the spectrometers to estimate atmospheric CO2 concentrations all over the globe.
Spectra acquired on the 200 MHz spectrometer were acquired at a [sup.13]C frequency of 50.3 MHz and with a MAS rate of 5 kHz, while those acquired on the 400MHz spectrometer were acquired at a [sup.13]C frequency of 100.6MHz and a MAS rate of 7kHz.
Two startup companies have been established on the basis of DESI and the portable mass spectrometer: Prosolia, Inc., of Indianapolis, has commercialized the DESI source, and Griffin Analytical Technologies LLC, of West Lafayette, Indiana, has commercialized miniature ion trap mass spectrometers.
