Abstract
A 250-mm imaging spectrograph was combined with a CCD detector, fiber-optic sampler, and diode laser (783 nm) to yield an efficient Raman spectrometer. A variety of sampling modes for liquids and solids were demonstrated, none of which required careful optical alignment. Of practical interest are spectra obtained from liquids inside glass containers, rapid (30 seconds each) spectral acquisition from successive solid and liquid samples, and spectra of normally fluorescent materials such as rhodamine 6G and common plastics.Keywords
