The Jobin Yvon T64000 Raman system is equipped with a triple Jobin Yvon T64000 spectrometer, Coherent mixed Ar+/Kr+ ion gas laser and CCD detector system. The experimental set-up also includes a confocal microscope and a xyz stage. The Cryovac Konti cooling cryostat for low temperature measurements makes it possible to obtain the micro-Raman spectra within the temperature range from 4 to 300 K. Through appropriate neutral filters of the T64000 system, the laser spot is driven by the mirror combination to the microscope system, which focuses a spot on the sample surface. The confocal microscope permits experiments on small size samples, with improved spatial, lateral and depth resolutions. The light scattered from the sample surface is redirected to the microscope and than orientated by mirrors to the triple monochromator. The spectral dispersed light from the monochromator enters the CCD (Charge Coupled Device) detector
