20 Years at the Forefront of Raman Imaging
The Raman imaging company WITec celebrates its 20th Anniversary. It was founded in 1997 as a 3-person spin-off from the Physics Department of the University of Ulm and has grown into a company of 60 employees including the Ulm headquarters and its branch offices in Spain, China, Japan, Singapore and the USA.
Through the past 20 years the company has established itself as a world-renowned manufacturer of confocal Raman imaging systems that embody the notion of German quality. Even the first production instrument, a Scanning Near-field Optical Microscope (SNOM/NSOM), continues to provide dependable, effective service.
From the beginning, WITec’s Raman microscopes have always been extremely fast, with integration times in the range of milliseconds per pixel. Back in the late 90s, integration times used to be one minute per pixel – thus WITec customers could measure far quicker than ever before. All WITec Raman imaging systems use the spectral information of a sample to produce an image that visualizes its chemical composition and structure. The company was also the first to offer combined microscopes that allow for imaging of a sample with several microscopy techniques that are integrated into one instrument. The latest innovation in correlative Raman imaging instruments is the Raman Imaging – Scanning Electron (RISE) microscope that has now captured the attention of many in the SEM community.
