Diffraction Gratings feature aberration correction.July 23, 2013 -
Guaranteed to meet groove profile and density specifications from prototype to production, Holographic Diffraction Gratings are aberration-corrected, meaning that unwanted optical effects such as keystone and smile are eliminated. Small-form-factor, temperature-insensitive products offer high SNR and low stray light performance. Applications include color management, plant phenotyping, pathogen detection, semiconductor fabrication, process monitoring, and remote sensing.

OEM-Specific Designs Feature Aberration Correction, High SNR, Low Stray Light Performance
Fitchburg, Massachusetts -- Headwall Photonics, Inc. is responding to increased demand from original equipment manufacturers (OEMs) for high-performance small-form-factor diffraction gratings used in their precision optical instruments.
Application areas include color management, plant phenotyping, pathogen detection, semiconductor fabrication, process monitoring, and remote sensing. Although end users need instruments having exceptionally high signal-to-noise (SNR), high spatial and spectral resolution, and low stray light, they also want simplified optical designs that lower size, weight, and cost. Aberration-corrected holographic diffraction gratings deliver these performance characteristics and are also temperature insensitive for suitability in applications that range from ground to space.
Original gratings, unlike those produced using replication techniques, are guaranteed to meet groove profile and density specifications from prototype to production. Headwall's gratings are aberration-corrected, meaning that unwanted optical effects such as keystone and smile are eliminated. Headwall's cost-effective, high-volume manufacturing process for all-original gratings means that OEMs can move from prototype to production rapidly.
"We are seeing a fundamental shift toward small form-factor spectral instruments across all the markets we serve," stated Headwall CEO David Bannon. "Our OEM customers can differentiate their instruments thanks to the unmatched optical precision and efficiency of our aberration-corrected holographic gratings." These instruments can be found not only in laboratory settings, but in airborne platforms and satellites as well. "Temperature insensitivity is a crucial differentiator for our diffractive optics technology," noted Bannon. "Customers want to make sure that the high optical performance that they demand is locked in no matter where or how their instrument is used." Headwall's gratings can routinely survive temperatures exceeding 80 degrees C (to 150 degrees C upon request).
Headwall's gratings are used in UV, VIS, NIR, IR, absorption spectroscopy, fluorescence spectroscopy, hyperspectral and Raman spectroscopy, CARS spectroscopy, and more. Designs can be fiber-matched and self-referencing if needed and are simplified by Headwall to reduce size, complexity, and cost.
