Re-INVENTING NIR Chemical Imaging
The HySPEC, a novel hyperspectral imaging instrument, utilizes a patented technique based on Tunable Laser Technology (OPO) to acquire 'chemical' images of heterogeneous samples. The HySPEC records multiple images of the target sample, each at a different wavelength. The complete set of 'pictures' provides a spectral signature of the target at each pixel. Supported by sophisticated Chemical Imaging analysis software, the HySPEC identifies, maps and quantifies sample constituents.

HySPEC Advantages
(vs. conventional spectral imagers)
Higher spectral resolution + multivariate image analysis
  = increased sensitivity
  = increased specificity
  = lower detection limits (trace analysis)
Orders of magnitude higher illumination intensity
  = larger FOV
Very low average power
  = no sample heating
Integrated fiber delivery
  = flexible architectures
  = custom designs
