Major Products/Services

WITec alpha300 Confocal Raman Microscope: The alpha300 R is a Raman imaging system focusing on high-resolution as well as high-speed spectra and image acquisition. The acquisition time for a single Raman spectrum is in the range of 1 ms or even below; thus, a complete Raman image consisting of tens of thousands of spectra can be obtained in 1 min or less. Differences in chemical composition, although completely invisible in the optical image, will be apparent in the Raman image and can be analyzed three-dimensionally with a resolution down to 200 nm.

WITec alpha500 Automated Confocal Raman & Atomic Force Microscope: The alpha500 is an automated confocal Raman and atomic force microscopy system incorporating a motorized sample stage for large samples and customized multi-area/multi-point measurements. It allows nondestructive chemical imaging with confocal Raman microscopy as well as high-resolution topography imaging with AFM using the integrated piezo scan-stage. Both modes can be run fully automatically, guaranteeing the most comprehensive surface inspection possibilities for systematic and routine research tasks or high-level quality control.


WITec Headquarters is located in Ulm, Germany, and includes the R&D department, production, sales & marketing, and administration. WITec Instruments Corp. in Knoxville, Tennessee, is responsible for North American sales and service activities.
