HR Evolution – Horiba

The spectrometer has a focal length of 800 mm, two grids (1800 and 600 grooves / µm), and a CCD detector (1024×256 px, -60 °C). There is also a 9-position filter system (from 100 to 0.01%) for EDGE and ULF (Ultra Low Frequency). The green Nd laser source (532 nm) has a power of 300 mW. High visualisation is by an Olympus BXFM petrographic microscope for transmitted and reflected light, connected with a 5Mpx camera (objectives: 5X, 10X, LWD 50X, and 100X). The presence of a motorised sample holder stage and the confocal system enables the acquisition of two- and three-dimensional profiles and maps in 2D and 3D at the (sub)µm scale. The system is compatible with a LINKAM THMS600 heating/freezing stage for analysis in the temperature range from 300 to -180°C.
