Near‑infrared spectroscopy enables fast, non‑destructive spectral acquisition, often within milliseconds, making it significantly faster than techniques like Raman. The MicroNIR family of handheld and process spectrometers is designed to capture high‑quality diffuse reflectance and transmission spectra quickly. This application note explains how to perform rapid, continuous spectral acquisition using a MicroNIR PAT instrument with MicroNIR Pro v3.2 software. Devices in the PAT series, including the USB‑connected PAT‑U and PAT‑L and the WiFi‑enabled PAT‑W, support efficient real‑time spectral collection for process monitoring and analysis.
