MD5 Dual Beam Spectrograph

A prealigned optical system that provides high throughput (f/2) and low stray light, as it disperses sample and reference spectra onto a single photodiode array, providing a self-compensating reference beam. A rugged and compact module designed for industrial applications, the MD5 has no moving parts and provides superb optical stability at a very attractive price.

Handheld, Multi-Channel Imaging Spectrometer Raman Discovery™

Integrated Raman Explorer™ Instruments

The Raman Explorer family of integrated spectrometers, designed and optimized for Raman imaging applications, has been expanded to include fully integrated spectrometer instruments as well as new configurations to take advantage of a range of different laser excitation wavelengths. These instruments take advantage of Headwall's patented, retro-reflective design in order to drive performance and high optical efficiency for the most demanding applications.

• Raman Explorer 785™ for 785 nm laser excitation
• Raman Explorer 532™ for 532 nm laser excitation
• Raman Explorer 532/685™ for dual laser excitation

Raman Explorer™

The first member of a family of multi-channel, multi-spectrum spectrometers based on Headwall's patented, retro-reflective concentric configuration - an innovative, high reciprocal dispersion design. The configurable multi-input design provides the ability to place multiple spectrums onto a single detector plane. The optical design yields high optical efficiency and imaging results with superior resolution, photometric accuracy, and improved quantitative analysis across extended spectral ranges.

• A high performance spectral engine for OEM applications
• Small instrument size enables laboratory and field analysis
• High efficiency optics optimized for Raman performance

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.

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:

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.
