WITec Confocal Raman Microscope/SNOM/AFM

NanoMaterials Facility







The Alpha300 is a user friendly Near-field Scanning Optical Microscopy (NSOM) that combines in a unique way the advantages of NSOM, Confocal Raman Microscopy and Atomic Force Microscopy in a single instrument. By simply rotating the objective turret, the user can choose from Confocal Microscopy, NSOM or AFM.

For NSOM, the alpha300 uses unique micro-fabricated SNOM-cantilever sensors for optical microscopy with spatial resolution below the diffraction limit. All standard optical modes such as transmission, reflection and fluorescence are available.

The Alpha300-Confocal Raman Microscope offers the unique ability to acquire chemical information non-destructively with a resolution down to the optical diffraction limit (~ 200 nm). Due to the confocal setup, it is not only possible to collect information from the sample surface, but also to look deep inside transparent samples and even obtain 3D information.

The Alpha300 integrates an AFM system with a scientific grade optical microscope for superior optical access and high-resolution sample survey. More specifically, the Digital Pulsed Force Mode in AFM, allowing local surface properties such as local adhesion or stiffness to be imaged along with topography on the nanometer scale.

Please note that the SNOM/AFM modes require special training, in addition to the standard tool training in order to qualify to use these modes.
