Headwall application engineers are available to help select the best system for your application.
The Headwall Photonics Hyperspec™ family of VNIR and NIR integrated hyperspectral imaging sensors provide the foundation for utilizing hyperspectral imaging to achieve superior spectral sensing and chemical imaging results for a range of mission-critical applications ranging from process monitoring to moving webs of product across conveyor lines to non-invasive medical imaging.
Headwall Photonics’ Hyperspec™ imaging spectrometer platform is built on a totally reflective concentric, f/2 optical design. These products are based on Headwall’s patented aberration-corrected imaging systems which feature the company’s “original”, high efficiency holographic gratings.
In order to minimize stray light and aberrations, the use of transmissive optical components are not used within the imaging spectrograph. This platform is further enhanced by a telecentric optical input design which enables superior spatial imaging.
Select the Hyperspec™ model which best satisfies spectral range, desired illumination distance, and spatial resolution. Then select the entrance slit width which best provides your desired spectral resolution; the standard slit width is 12.5 microns wide. By choosing a wider slit width, spectral resolution will be approximately broadened by a factor of the increased dimension (example: 25 um =2x). The objective lenses on Hyperspec imaging sensors are field interchangeable, providing the ability to vary the FOV and IFOV within the application scene.
