The SENTERRA II is a confocal Raman microscope designed for straightforward, non-stop operation. Its high degree of automation allows fast and easy Raman imaging for failure analysis, quality control and scientific research. First, the SENTERRA II is fully automated, including self-diagnosis and instrument tests like OQ and PQ. Change a laser with a simple mouse click, and afterwards, the filter and grating are adjusted automatically.Naturally, the SENTERRA II offers excellent sensitivity combined with pristine spectral and Raman Imaging performance. But the real powerhouse of this confocal Raman microscope is our SureCalTM technology.Let us briefly repeat one of the most important principles of Raman technology: External factors affect the optical and mechanical components in every Raman microscope, especially heat, component changes and vibrations. Ultimately, this induces wavenumber shifts, which must be compensated by regular recalibrations.
