Hyperspectral Imaging Spectrometer Applications
HORIBA has developed a unique hyperspectral imaging spectrometer with an integrated scientific CMOS camera (12-16 bit) featuring HDR (95dB Dynamic Range and 1.7e- noise) and 95% Q.E peak efficiency:
PoliSpectra® H116 features broad UV-NIR coverage in one acquisition (185-1050 nm) combined with the highest spectral resolution (<1 nm).
The elegant all-concentric design combines high spatial and spectral resolution using a type-I holographic diffraction grating. This system is used as a line-scanning instrument (push-broom) that collects full spectral data simultaneously, across the input slit height at 188 frames per second (or higher with AOI/binning).
