3-D Chemical Imaging Combined with AFM

Witec introduces the Alpha 500 and Alpha 700 microscopy series for automated Confocal Raman Imaging and Atomic Force Microscopy (AFM) on large samples. They are the first instruments on the market to combine Confocal Raman Microscopy for 3-D Chemical Imaging and AFM for high resolution structural imaging in an automated system. A motorized sample stage with a travel range of 150 x 100 mm for the Alpha 500 and 350 x 300 mm for the Alpha700 allows multi-area/multi-point measurements or overview scans on an arbitrary, user-defined number of measurement points. Specific automated functions such as an integrated auto-focus and an automatic AFM-tip approach guarantee that standardized routine measurement procedures or manually defined sequences can be performed without any ongoing process control by an operator.
