NLIR, a global leader in high-speed infrared sensing solutions, offers the REFLECTION Interface, a next-generation optical interface designed to bring real-time, non-invasive mid-infrared (MIR) reflection measurements to the forefront of industrial and research environments, offering unprecedented flexibility, precision, and scalability.

The REFLECTION Interface is a modular system composed of two tightly integrated components: the AURALIS Light Source and the SAMPLER Accessory. Together, they form a complete optical pathway for capturing MIR spectral data from surfaces without the need for contact or sample preparation. Operating in the 2 to 5 µm range, the interface enables users to analyze material surfaces in real time with exceptional detail, making it ideal for complex process monitoring and quality control tasks.

The AURALIS Light Source provides intense, wideband (1 to 10 µm) MIR illumination using a silicon carbide (SiC) element heated to high temperatures to produce incoherent broadband radiation, and a calcium fluoride protective window. It delivers up to 0.5 W/cm² intensity at 150 mm working distance, with active thermal management ensuring a long operational lifetime of 5000 hours. The SAMPLER Accessory collects the reflected signal within the 2 - 5 μm range using a 1 - 2 mm spot size and transfers it via an optical fiber to the spectrometer. Its compact design supports mounting with M3 and M4 threads, offering precision alignment and structural stability.

NLIR has designed the system for seamless integration with its flagship MIDWAVE Spectrometer, delivering a compact and powerful solution that can be easily adapted into existing production setups. The REFLECTION Interface allows for high-throughput material analysis even in challenging environments where speed and reliability are critical.

The applications for this technology are wide-ranging. From inspecting advanced coatings in the aerospace and automotive industries to monitoring polymer characteristics in recycling operations, and from evaluating laser processes to analyzing historic artwork, the REFLECTION Interface provides a flexible and non-destructive method for understanding the molecular composition of materials.

The REFLECTION Interface from NLIR continues to lead the field in making high-performance mid-infrared technology more accessible, adaptable, and relevant to real-world challenges. As industries seek smarter, faster, and more sustainable solutions, NLIR is committed to providing the tools that make precision spectroscopy a scalable part of the manufacturing and research ecosystem.
