LabRAM HR Evolution: Raman Microscopy with Photoluminescence
The Raman spectroscopy is a powerful technique for studying of materials in various forms (solid, liquid, gas) and LabRAM HR Evolution Raman microscope is capable to do micro and macro measurements with true confocal imaging in 2D and 3D. The Raman spectroscopy provides vibrational modes which are affected by mass, bond strength and symmetry of molecules (unit of gas/liquid), or primitive unit cell (unit of solid). Any physical/chemical factor affecting the surrounding of atoms (such as defects or impurities) can be probed through Raman spectrum features.
The key features of MRS includes:
-
⦁ Raman range: 50 cm-1 – 4000 cm-1
⦁ Spectral resolution: ~ 0.2 cm-1; Spatial resolution: 0.5 micrometer
⦁ Laser excitation wavelengths: 325 nm (He-Cd); 532 nm; 785 nm; and 976 nm
⦁ Photoluminescence measurements in 400-1000 nm
⦁ Objectives: 40X (NUV); 50X (LWD); 5X; 10X; 100X
⦁ 2D and 3D imaging with 0.01µm Z-resolution
⦁ Open Electrode CCD air-cooled to -60°C
⦁ Gratings: 600, 1800, 2400 g/mm
