The aura is a miniature broadband FTIR spectrometer designed for cutting-edge infrared and terahertz applications. With a footprint of only 15 × 10 × 10 cm, it combines compactness with an exceptionally wide spectral range from 5 µm to 500 µm (0.6–100 THz). The system is built entirely on reflective optics and a lamellar grating design, ensuring alignment-free operation, long-term stability, and compatibility with high-vacuum environments down to 10⁻⁶ bar. Delivering spectral resolution down to 1 cm⁻¹, the aura enables researchers and industry users alike to perform precise and reliable measurements in a portable form factor.

Typical applications include synchrotron and FEL diagnostics, time-resolved spectroscopy, and material characterization in the mid-IR to THz regime.
