Raman confocal microscope
About
Raman confocal microscope for characterisation of materials
Description
The equipment is a Horiba XploRA Raman confocal microscope. It has two excitation wavelengths: 532nm (usually best for inorganic material characterisation) and 785nm (typically best for organic or photoluminescent materials). It is equipped with a range of objectives from 10x to 100x magnification. These objectives are darkfield (suited for imaging of transparent materials). Both single point and mapping are possible
Technical specifications:
– 532nm (usually best for inorganic material characterisation) and 785 nm (typically best for organic or photoluminescent materials) lasers
– Range of objectives from 10x to 100x
– Darkfield capabilities
– Single point or mapping possible
– Typical sample size is microscope slide
Case study:
The user is trying to see the influence of processing parameters (e.g. annealing temperature, gases mixes) on the composition of prepared thin film. Acquisition of Raman spectra might give insight into the composition and distribution if sample is heterogeneous
