WITec 3D Raman Imaging – Solutions for Chemical Analysis and Correlative Microscopy

WITec is a manufacturer of high-resolution optical and scanning probe microscopy solutions for scientific and industrial applications. The company’s product line features a confocal Raman microscope designed for highest sensitivity and resolution, an AFM for material research and nanotechnology and a near-field scanning optical microscope, using unique cantilever technology.

Since its founding in 1997, WITec has established itself as a market leader in this field of nano-analytical microscope systems. As reflected in WITec’s maxim "Focus Innovations", our success is based on constantly introducing new technologies and a commitment to maintaining customer satisfaction through high-quality, flexible and innovative products.

With the release of the first Confocal Raman Imaging system in 1999, WITec outperformed the existing Raman mapping techniques in terms of sensitivity, speed and lateral resolution, pioneering Raman spectroscopy as a tool for true 3D chemical imaging. The modular design of WITec microscopes allows the integration of Confocal Raman and Scanning Probe Microscopy in one system. This innovation initiated the current boom in combined Raman/SPM systems.

A dedicated international market approach with an established service and support experience in the various regions of the world is one of our key strengths, evidenced by our widespread network of WITec representatives as well as branch offices in the US, Singapore, Japan, China, and Spain.

The WITec Product Line

  • alpha300 series
    The alpha300 series for high-resolution 3D Raman imaging and Scanning Probe Microscopy is one of the most advanced and flexible nano- and macro-analytical research tools available. A modular setup allows for a variety of configurations or extensions to meet individual scientific requirements or budget environments.

  • alpha300 access
    The alpha300 access is a micro-Raman single-spot analysis and mapping microscope. It was specifically engineered for budget-conscious customers with high demands on instrument performance. The high-quality WITec microscope architecture of the access is the basis for its full upgradability. Whenever needed, the alpha300 access can be easily and quickly adapted to new requirements.

  • apyron
    The WITec apyron is an intuitive automated microscope system for Raman spectroscopy and chemical imaging. The push-button principle of the system has the advantage of drastically reducing the time required to become familiar with the operation of the instrument, which accelerates the initiation of measurements and increases the rate of sample turnover greatly compared to conventional systems. With the apyron‘s straightforward interface the user can concentrate entirely on the experiment without being distracted by complex operating procedures.

  • RISE Microscopy
    RISE Microscopy is a correlative technique that combines Raman Imaging and Scanning Electron microscopy into one integrated system, allowing ultra-structural surface properties to be linked to molecular compound information. With this combination samples are automatically transferred from one measuring position to the other within the vacuum chamber of the SEM for the entirety of the measurement procedure, thus streamlining the workflow and drastically improving the instrument‘s ease of use.

Fields of applications are very broad and range from life sciences and pharmaceutical research to materials sciences and nanotechnology.
