The secret to straightforward Raman micoscopy

Automation is the SENTERRA II's key feature. It allows the user to concentrate on the essential things: the analytical problem, the Raman measurement and more importantly, the results.

SENTERRA II technical features:

  • Fully automated hardware
  • One-click switching of 4 built-in lasers
  • SureCalTM calibration technology
  • Fast 3D Raman imaging
  • Automate your own workflows in minutes
  • Powerful analysis and identification tools
  • FT-Raman for minimized fluorescence in
    combination with FTIR instrumentation
SENTERRA II provides:
  • Smooth user experience
  • Research-grade performance
  • Superb wavenumber precision
  • Self-diagnosis and automated OQ/PQ
  • Virtually maintenance-free operation
  • 100% GMP & 21 CFR p11 compliance

SENTERRA II applications:

  • Pharmaceuticals
  • Material Science
  • Polymers & Plastics
  • Environmental
  • Forensics


Three Major Design Choices

Reproducibility, Precision and User-Safety in Raman Microscopy

First, the SENTERRA II is fully automated including self-diagnosis and instrument tests like OQ and PQ. Change a laser by a simple mouse-click and afterwards, filter and grating are adjusted automatically.

Second, to use this automation to its full extent, we rethought calibration and created the patented SureCalTM technology. It continuously recalibrates the device and allows permanent sub-wavenumber precision.

Third, it’s about user safety - especially when beginners or students are involved. A class 1 laser housing and interlock always protects the user of any harmful laser radiation.

Your Advantage in Science and Industry

SureCal Continuous Raman Calibration Technology

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.

Thanks to SureCalTM, the SENTERRA II is the only Raman microscope that is always calibrated. Don't waste your valuable time with recalibration - start analyzing. No matter if it is a quick material identification or the collection of large data sets for PCA or other statistical methods.

Dedicate your Raman Microscope to Life-Science

Senterra II can also be configured with an inverted microscope without compromising any functionality. The inverted Raman microscope gives open access for sample handling , which is particularly favorable in characterization of live tissue and cells.

Besides cell research, the inverted microscope also brings advantages in researches like in vitro pharmaceutical verification and in situ Raman measurement that requests better access to the microscopic stage.
