The present invention is an optical device for small spot analysis by diffuse reflectance using fiber optic interfaced spectrometers. The device comprises a source of electromagnetic radiation and a set of mirrors designed to project most of the radiation from the said source onto a less than 1 mm diameter spot on the sample, collect a portion of the radiation reflected by the sample and refocus this reflected radiation into an optical fiber. The said optical fiber then brings the said reflected radiation into a fiber optic interfaced spectrometer for spectral analysis. A means for the magnified viewing of the sample and the precise selection of the sampling spot for analysis is integrated into the invented device. Adding a digital camera and a laser module to the said device enables nearly simultaneous multimodal analysis of the same sampling spot by diffuse reflectance, Raman, and fluorescence spectroscopy and by image analysis.
