Renishaw inVia micro-Raman spectrometer

The setup contains a regular upright microscope as well as an open-space microscope for special experiments. Argon laser lines (514, 488, 457 nm) and 830 nm from a laser diode with corresponding line-rejection filters are available for excitation. The regular microscope allows automatic µm-resolution confocal mapping of Raman or luminescence signal. The open-space microscope can accommodate a cold-finger helium-bath cryostat for low-temperature measurements.
