TE-Cooled Benchtop Raman Spectrometer

The Cora 7X00 series of high-performance Raman spectrometers is designed for research and advanced industrial applications. With its compact and rugged housing it easily fits onto a lab bench or in a rack. You can choose one of three different wavelengths: 532 nm, 785 nm, or 1064 nm. The high-quality optics with two high-efficiency transmission gratings provides a high spectral resolution. Soft- or deep-cooled detectors reduce noise. The fiber-optic probe and operation via external PC make the Cora 7X00 series an easy–to-use instrument with maximum flexibility for various kinds of samples.

Key Features

Choice of wavelength depending on sample type

  • The 532 nm wavelength of Cora 7100 is widely used in material analysis.
  • The 785 nm wavelength of Cora 7200 is the most common Raman wavelength in various industries.
  • The 1064 nm wavelength of Cora 7300 is the most suitable option for samples that show fluorescence or for measurements in fluorescent environments.

High performance

  • Thermo-electrically soft- or deep-cooled CCD or InGaAs detectors generate high-resolution Raman spectra with low noise levels.
  • Resolution at 532 nm and 785 nm: up to 4 cm-1 to 5 cm-1 over a spectral range of 100 cm-1 to 3200 cm-1
  • Resolution for 1064 nm: 10 cm-1 to 15 cm-1 over a range of 200 cm-1 to 1800 cm-1

Fast measurements

  • High efficiency and high-throughput transmission gratings (VPG) increase sensitivity and allow short spectral acquisition times.

Flexible fiber-optic probe

  • The probe can be moved around for measuring (standard probe length: 1.5 m).
  • The spectrometer can be mounted in a rack while measurements take place on the lab bench or in an experimental setup nearby
  • You are flexible regarding sample dimensions – there are no limitations from a sample compartment.
  • It is possible to measure many different kinds of samples (liquid, solid, semi-solid) with special vial holders designed for use with the fiber-optic probe.

Straightforward PC or touchscreen operation

  • With the wireless option for PC or tablet control of the instrument you can start measurements from a bigger screen.
  • Factory-, user-built, or third-party libraries make it possible to identify substances within seconds.
  • You can manage user rights in your lab with the help of three different user levels and access control.
  • Make your measurements traceable due to built-in event logging.
  • The software guides you through the calibration routine.


  • There are no moving parts except the fan – that means almost no wear and tear, and low maintenance costs.
  • The shock-resistant optical engine is built to last
