In order to document the precision of the new focus stabilization, a very long measurement time of 46 hours was chosen.WITec, industry-leading manufacturer of Raman imaging and correlative microscopy systems, has started shipping its Suite FIVE data acquisition, evaluation and processing software with the new ability to compensate for thermal and mechanical variations during long-term measurements.

Confocal Raman microscopy investigations performed on delicate samples often require lower excitation power and a corresponding increase in acquisition time. Active focus stabilization ensures that the ideal focus between the microscope objective and sample is maintained and signal collection is unaffected while temperature or humidity changes. This is accomplished by an automatic routine that uses a reference point to optimize the Raman signal.

This most recent development in WITec’s ongoing effort to provide results-oriented functionality is a standard and fully-integrated enhancement to the powerful Suite FIVE software package.

About WITec

WITec is a leading manufacturer of confocal and scanning-probe microscopes for state-of-the-art Raman Imaging, Atomic Force Microscopy (AFM) and Scanning Near-field Optical Microscopy (SNOM) in addition to being the developer of the integrated Raman Imaging and Scanning Electron (RISE) microscopy. WITec’s headquarters is located in Ulm, Germany, where all WITec products are developed and produced. Branch offices in USA, Japan, Singapore, China and Spain provide a worldwide sales and support network. WITec has been distinguished by its innovative product portfolio and a microscope design that enables combinations of the various imaging techniques within one system. An exemplar of the company’s breakthrough development is the world’s first integrated Raman-AFM microscope. To this day, WITec’s confocal microscopes are unrivaled in sensitivity, resolution and imaging capabilities. Significant innovation awards such as the Achema Innovation Award 2015 for the fully automated apyron microscope and a Prism Award 2015 for RISE microscopy document WITec’s enduring success and innovative strength.
