WITec, a leader in nano-analytical microscopy systems, has launched the new True Surface Microscopy option. The core element of this revolutionary imaging mode is an integrated sensor for optical profilometry. Large-area topographic coordinates from the profilometer measurement can be precisely correlated with the large-area confocal Raman imaging data. This allows for the first time confocal Raman imaging along heavily inclined or very rough samples with the true surface held in constant focus while maintaining the highest confocality. With the new imaging mode, samples that had previously required extensive preparation in order to obtain a certain surface flatness can now be effortlessly and automatically characterized as they are. Complete system control, as well as extensive data evaluation, are integrated within the WITec Control and WITec Project software environment, guaranteeing renowned ease-of-use.
“The integrated combination of optical profilometry and large-area confocal
Raman imaging is the next evolutionary leap in cutting-edge microscope
configurations.” says Dr. Olaf Hollricher, WITec Managing Director R&D.
“Only an inherently modular instrument design can enable such a seamless
incorporation of a groundbreaking and complementary imaging technique into the
present product line of Raman-AFM systems.”
The profilometry capabilities of True Surface Imaging mode allows scan ranges
of up to 50 x 100 mm with a spatial resolution on the order of 100 nm
vertically and 10 µm laterally. Measuring distances of 10 mm and more provide
flexibility for variable sample size requirements. In combination with AFM, the
profilometer can even be used as a pre-inspection tool to determine topographic
features of interest for high-resolution AFM investigations on large samples.
The overall performance and exceptionally accurate imaging capabilities of True
Surface Microscopy are beneficial for many applications, including the
characterization of micromechanical, medical or semiconductor devices, the
mapping of functionalized surfaces, or the imaging of bio-medical or
pharmaceutical material surface properties.
