Rapid, non-invasive diagnosis is a crucial goal of healthcare. With hyperspectral and Raman imaging, life-saving decisions can be made. Headwall’s Hyperspec instruments offer medical researchers access to accurate, calibrated, and repeatable spectral analysis. When used as a multi-channel spectrometer, high-throughput screening experiments can be conducted where high spectral resolution, spatial differentiation, and channel separation are all critical parameters.
Raman imaging differs from hyperspectral because the sample is excited with a laser rather than illuminated by a light source. Molecules in the sample ‘scatter’ the laser light, which is then collected and analyzed by the Raman spectrometer to produce a Raman spectrum. Unknown molecular compounds can be rapidly identified with this technique.
