Hyperspec™ VS Imaging Spectrographs

Headwall Photonics’ Hyperspec™ VS family of imaging spectrographs are very compact, high-throughput imaging spectrographs for use with the latest large-format focal plane array detectors. With an exceptionally large and distortion-free image plane, these concentric design spectrographs are intended for hyperspectral imaging applications where very high spectral-spatial resolution is required.

 
 

Employing our world-renowned original holographic diffraction gratings to dramatically reduce stray light, the Hyperspec™ VS family employs Headwall’s patented, aberration-corrected convex grating designs which eliminate focal plane distortions such as keystone and smile. High throughput optics (f/2.0 VNIR, f/2.3 NIR, f/2.5 SWIR) ensure high signal to noise ratios. The concentric spectrograph design enables exceptional imaging over the full extent of an 18 mm tall slit, providing the highest spatial resolution available. The entrance slit is 12 µm wide resulting in superb spectral resolution, which permits “binning” for enhanced sensitivity.
