Sandia National Laboratories researchers prepare a hyperspectral confocal microscope for measurement of a biological specimen. The new microscope, shown on the left, was designed and fabricated at Sandia. The hyperspectral microscope uses laser excitation and collects 512 spectral emission wavelengths at each voxel in the image over the spectral range from 500 to 800 nanometers at a spectral resolution of 1-3 nm and at an imaging rate of 8,300 spectra/second (with extension to 64,000 spectra/sec in the future).
