By designing custom short-wave infrared (SWIR) optical filters with precise bandwidths, cut-ons, and cut-offs — and optimizing coatings for durability — Chroma enabled the sensor to effectively isolate chemical signatures in field conditions. The result was a highly optimized, rugged sensor system that met the customer’s performance and environmental demands. Industry: Oil and Gas Technology Focus: SWIR optical detection integrated into a compact sensor system The customer required spectral precision and rugged performance in challenging field environments. The customer’s sensor system demanded isolation of specific SWIR wavelengths associated with chemical contaminants, along with precise spectral characteristics including bandwidth, cut-on, and cut-off performance, all while remaining compatible with a compact instrument design and tight optical paths. Off-the-shelf filters were unable to meet this combination of spectral, mechanical, and environmental requirements. Solution Chroma Technology leveraged its expertise in SWIR filter design to develop a customized solution. The team adapted existing high-performance SWIR technology and collaborated closely with the customer to refine and optimize the design for real-world instrument conditions. Chroma also provided guidance on instrument design adjustments to maximize performance. This collaborative process ensured seamless integration into the customer’s sensing platform. Key Features High transmission Maximum light throughput in target bands to preserve signal strength to the detector. Deep out-of-band blocking Sharp spectral transitions Precise band placement Implementation Optimize coatings for beam shape and angle of incidence Ensure compatibility with compact optical paths Utilize sputter-coated filters for enhanced thermal and mechanical durability Results » Precise detection of contaminants at targeted SWIR wavelengths » Successful validation testing with performance meeting customer expectations Conclusion This project demonstrates that early collaboration and iterative refinement are key to delivering optimized optical solutions. Rugged sputtered coatings proved essential for industrial durability, while precise spectral engineering enabled accurate detection of chemical signatures. The success of this engagement has laid the groundwork for continued partnership and future filter development. Does your sensor application demand more than off-the-shelf optics?
