Versatile instrument that has been proving its value every day.
Application Area: Surface characterization and polymer morphology
"Excellent instrument that is easy to use and has high resolution. Beside chemical information, it allows for morphology information and height profiling of surfaces. We are very content with the instrument."
True Surface Microscopy - Confocal Microscopy Along with Large Area Optical Profiling
WITec´s new True Surface Microscopy option (patent pending) allows confocal Raman imaging guided by surface topography. Confocal microscopy is often desirable due to its suppression of out-of-focus light but can be challenging when analyzing large or rough surfaces. In these cases, only those points that are in focus contribute to the image. True Surface Microscopy follows the surface topography with high precision, so that even rough or inclined samples always stay in focus. To achieve this unique capability, the WITec alpha500 series can be equipped with a highly precise sensor for optical profilometry. The topographic coordinates from the profilometer measurement are used to perfectly follow the sample surface in confocal Raman imaging mode. The result is an image revealing chemical properties at the surface of the sample, even if this surface is rough or inclined.
