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.

Automated Raman Imaging - WITec apyron: The new fully automated, easy-to-use Raman imaging system apyron features unrivaled spectral resolution in 3D confocal Raman imaging. The absolute laser power determination and regulation in 0.1 milliwatt steps preserves delicate samples and guarantees the reproducibility of measurement conditions. The UHTS 600, a new 600 mm focal length spectrometer, designed specifically for automated Raman imaging, enables challenging experiments at even very low light intensities surpassing any previous standard of performance.


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