The objective of this purchase is to acquire a high-performance research-grade Fourier-transform infrared spectrometer capable of advanced infrared spectroscopic measurements across the mid-IR and far-IR regions, with high spectral resolution, vacuum optics, time-resolved measurement capability, multiple detector/source configurations, and flexible sample/accessory compatibility. The system will support demanding R&D applications, including high-resolution spectral analysis, rapid-scan and step-scan experiments, far-IR measurements, reflectance/transmission/ATR measurements, and data acquisition, processing, validation, reporting, and management through integrated spectroscopy software
