Application
Raman Microscopy is applicable for the Phase and chemical identification, characterization of molecular structure, their bonding effect, environment and stress of any material of different disciplines viz. Geological, Physical, Chemical, Biological and forensic sciences. Raman spectra provides characteristic vibrational frequencies by which chemical composition and structure of material can be identified, crystallographic orientation of the sample, identification of particles in micrometre dimension variation in composition can be mapped to provide images based on the distribution of molecular composition.
Features
- Micro-Raman spectrometer-In-Via reflex Raman spectroscopy system combined with research grade Leica microscope allows scatter, line, area mapping and confocal depth profiling.
- Excitation Source: 4 types of lasers- 325 nm, 532 nm, 632 nm and 785 nm with different magnification lenses.
- Ultralow cut off filter for 532 nm excitation to record low frequency (~10 cm-1) Raman spectra
- Motorized neutral density filters offering 16 different power levels from 0.00005 to 100%.
- Micro-PL measurement facility with 325 nm laser
Capability
