Description: Micro-Raman Spectrometer uses a fingerprint technique to identify materials based on vibrations. Its sensitivity can give information on composition and strain. Capabilities: 4 lasers: 355nm, 532 nm, 633nm and 785 nm. Spatial resolution: ~ 0.5 microns. Spectral resolution: < 1 cm-1. 2 spectrometers: depending on applications: 750 mm visible. 328 mm visible and Near IR optimized Si detector. (New 2025) Can collect down to 5 cm-1 with 532nm laser. Polarization control (both incident laser (including circularly polarized incident laser and signal). Raman mapping capabilities (New high-resolution stage installed in 2017). Photoluminescence from 400nm to ~1000nm. No or minimal sample preparation: Nondestructive. Works for most liquid, gas or solid. Pure phase, multi-phases, glasses, single crystals and even artwork, such as paintings. Some applications: Phase identification (compare to a published spectrum/ standard) investigate small chemical/structural. Strain/defects in some material. Sample mapping. In situ characterization at high pressure and or temperature or within a medium.
