WITec's TrueSurface microscopy is now available as an integrated option for the alpha300 microscope series. This development enables topographic Raman imaging on large samples for WITec instruments. The imaging mode is also available as an upgrade for installed alpha300 and alpha500 systems.

The functional core of the measurement mode is the sensor for optical profilometry, now fixed in the microscope objective turret. The system measures the surface topography of large samples and correlates it with confocal Raman microscopy. This allows rough or heavily inclined samples to be chemically characterized while also being confocally imaged.
