What is witec360?

witec360 is a confocal Raman microscope platform for Raman spectroscopy, 2D Raman mapping, 3D Raman imaging, line scanning, depth profiling and time-dependent measurements. Each pixel in a Raman map can contain a complete Raman spectrum, allowing users to extract chemical, structural, phase, strain or compositional information at specific sample locations.

The main strength of witec360 is its modular architecture. Users can configure the system for current experimental requirements and expand it later with additional lasers, spectrometers, stages, automation, polarization modules, TrueSurface, AFM, SNOM, photoluminescence, fluorescence, TCSPC, SHG/THG or other correlative microscopy techniques as research needs evolve.

Why Choose witec360 for Raman Imaging?

Modern research often requires more than a single Raman spectrum. Researchers need to visualize chemical composition, structure and material properties across large areas or in three dimensions. witec360 addresses this need with optimized optics, high-performance spectroscopy, intuitive software and advanced automation that accelerate data acquisition, improve reproducibility and simplify daily operation.

By integrating correlative microscopy techniques, witec360 enables users to connect Raman information with morphology, topography, mechanical properties, photoluminescence, optical structure or data from complementary techniques. This is especially valuable for advanced materials, semiconductors, polymers, 2D materials, pharmaceuticals and complex biological samples.
