Map spectral responses across microscopic surfaces

CRAIC Technologies says the Spectral Surface Mapping (S2M) capabilities of its UV-visible-NIR microspectrophotometers gives users the ability to map the spectral responses across of surfaces of their samples, point-by-point. With microscopic spatial resolution, surface profiles can be created using UV-visible-NIR transmission, absorbance, emission, fluorescence and polarisation microspectral data.

S2M can create maps from Raman microspectral data generated by the Craic Apollo Raman microspectrometer. Microspectrometers can now created highly detailed spectral maps with micron scale resolution rapidly and automatically.

“We worked to develop the Spectral Surface Mapping package because of customer requests. Our customers wanted the ability to automatically survey and characterise the entire surface of samples by their spectral characteristics. They also wanted a high spatial resolution” said Paul Martin, president of Craic Technologies.

“The S2M package allows you to collect spectral data from thousands of points with a user defined mapping pattern. And because our customers deal with so many different types of microspectroscopy, we gave S2M the ability to map UV-visible-NIR transmission, absorbance, reflectance, and even emission microspectra, all with the same tool”.

Spectral Surface Mapping is a plug-in software module used with Craic’s Lambdafire microspectrometer software. It allows a user to automatically take spectral measurements with user-defined mapping patterns that reach to the movement limits of the stage itself. With the ability to measure up to a million points, high definition maps of the spectral response of the surface of a sample may be generated.
