Product Overview
The Bruker SENTERRA II redefines user accessibility in confocal Raman microscopy by combining high-end spectroscopic performance with a high level of hardware automation. Designed for a "non-stop" analytical workflow, the system features a compact, integrated design where the spectrometer is built directly into the microscope stand. This efficiency allows users, from students to advanced researchers, to transition from sample visualization to high-quality Raman imaging with just a few clicks, making it an ideal platform for multi-user environments, failure analysis, and routine quality control.
At the heart of the SENTERRA II is a modular and intelligent architecture that adapts to diverse research needs. The system supports up to four internal excitation lasers, which can be switched instantly with automatic adjustment of filters and gratings to prevent configuration errors. Its modularity extends to specialized configurations, such as an inverted microscope for life science applications or the inclusion of an FT-Raman module to minimize background fluorescence in challenging samples. By integrating patented technologies like SureCal™ for permanent wavelength stability and Adaptive Chemical Imaging™ for automated data evaluation, the SENTERRA II ensures that scientists spend less time on recalibration and more time on high-impact discovery.
