Hyperspec™ VS Imaging Spectrographs

Integrated hyperspectral imaging sensors for industrial and life sciences applications

Superb f/2.0, f/2.3 & f/2.5 designs for high optical throughput

Aberration-corrected imaging for harsh environments

Up to 18 mm x 6 mm focal plane with very low distortion

Extremely low stray light & high signal to noise ratios

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.

Expanding on the Hyperspec™ VS-15 product, Headwall offers these proven, fourth generation sensors. The Hyperspec™ VS-25 imaging spectrograph covers 400-1000 nm over a 6 mm dispersion with extremely high optical efficiency and resolution. For applications in the NIR region, from 900nm to 1700nm, Headwall offers the Hyperspec™ VS-50 spectrograph and the Hyperspec™ VS-75 for the SWIR region of 1000nm to 2500nm. All of these products are designed for imaging in harsh environments and are available as a spectrograph or as complete, integrated hyperspectral imaging instruments.
