Product Name: Hyperspec™ VS Family of Imaging Spectrographs

Product Description

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.

Detector Mounts
Mounted in an enclosure only 5.0” x 6.0” x 4.0” in size, the Hyperspec™
VS family offers very simple and robust construction and has no moving parts to
fail. A large detector flange permits sturdy mounting for a variety of detectors
operating in a wide range of harsh application environments (airborne, space
platform, and industrial).
