Headwall Photonics spectroscopy spectrograph

Headwall Photonics is the leading designer and manufacturer of hyperspectral imaging sensors.


Headwall Photonics has been at the forefront of hyperspectral imaging since 1994 while continuously advancing the capabilities of its sensor products. With its patented, aberration-corrected Hyperspec™ sensors, the company has established a worldwide reputation for exceptional imaging performance.

Up to this point, wide area or high volume sampling was limited to single point measurement techniques; now hyperspectral imagers provide much greater sampling capability when deployed as a lens-based system or as multi-point/multi-channel instruments. Headwall's patented, f/2, aberration-corrected hyperspectral sensors provide users with unparalleled imaging performance free of image distortion.

Hyperspec Spectral Ranges

Key attributes of Hyperspec™ instruments include:

  • All reflective, concentric design
  • High efficiency diamond-turned or "original" holographic gratings
  • Aberration-corrected imaging
  • Tall image slit for wide field of view
  • High signal-to-noise
  • Lightweight, small form factor
  • Robust with no moving parts
  • No prism or transmissive optics

Designed for imaging in harsh environments, Headwall's Hyperspec™ and Micro-Hyperspec™ sensors lead the industry in spectral and spatial imaging performance. Headwall offers a range of high performance, concentric imaging sensors which can be readily customized performance and cost. Standard COTS hyperspectral sensors include:

Original Holographic Diffraction Gratings

Gratings for Multiple Applications


Headwall Photonics, Inc. has the history and leadership as a OEM supplier of original holographic diffraction gratings for multiple applications. Headwall's gratings include planar, aberration-corrected concave/convex, and Rowland Circle designs. Markets include telecommunications, spectroscopy, colorimetry, biomedical, and other analytical applications.

Headwall Photonics, Inc. has proven that the highest performance diffraction gratings cannot be manufactured with "replication" techniques, so we have continuously refined our process to deliver only "original" gratings, making Headwall the only company in the world that can make this statement.

The original grating manufacturing technique can accurately create the groove profiles necessary for high efficiency and low PDL. Other grating manufacturing techniques that involve replication cannot reproducibly create the subtle groove profiles required for high performance. The result of Headwall's original technology is efficiencies in excess of 90% on our High Efficiency / Low Loss designs and PDL as low as a few tenths of a dB on our LPDL designs.

The holographic original technique permits the recording of gratings on concave and convex surfaces. Headwall have pioneered the development of aberration-corrected concave gratings and continue to refine our designs to deliver the highest performance. We believe this technology will enable the future evolution of designs that are simpler and less expensive, without compromising performance.
