Micro-Raman-Spectroscopy

HORIBA JOBIN-YVON Labram-HR800 spectrometer, excited by a frequency-doubled Nd-YAG laser (100mW, 532nm), a He-Ne laser (17mW, 633nm) and a diode laser (300mW, 785nm). Several objectives up to 100x magnification and 13 mm working distance. Lateral and depth resolution down to 5µm3, achievable spectral resolution below 1 cm-1. Motor-driven, computer-controlled x-y-stage and piezo-autofocus for mapping purposes. Heating- and cooling- stages by LINKAM for temperature-controlled measurements between -196° and 1500°C. Super-head and glas-fibre options. Several commercial spectra databases for identification of organic and inorganic compounds.
