The Si-MIR Core is a compact MIR sensing setup designed for researchers and developers exploring Si-Ware’s miniaturized FT-IR technology across different materials. Its compact and modular design and low power consumption make it suitable for experiments that demonstrate the use of MIR spectral sensing in environments where traditional MIR spectrometers are impractical. It provides a stable and flexible setup to study MIR spectral behavior, assess feasibility on specific samples, and support early system design decisions, making it an accessible starting point for teams evaluating how miniature MIR sensing could enable new applications or product concepts.
