The VERTEX 80 and the VERTEX 80v vacuum FT-IR spectrometers from Bruker are based on the actively aligned UltraScan™ interferometer, which provide PEAK spectral resolution. The ultimate stability and sensitivity are guaranteed by the precise linear air bearing scanner and PEAK quality optics.
The VERTEX 80v is an evacuated optics bench capable of eliminating atmospheric moisture absorptions for ultimate stability and sensitivity; enabling demanding experiments such as UV spectral range measurements, step-scan, ultra fast rapidscan, or high resolution.
The VERTEX 80/80v optics design allows both PEAK instrument performance and PEAK flexibility. The unique Bruker Optics DigiTect™ technology allows easy and reproducible detector exchange by the instrument user, guarantees PEAK signal-to-noise ratio, and prevents external signal disturbance.
The two optional external detector ports accommodate the liquid He dewars of bolometer and/or hot electron detectors. Together with the external water cooled high power Hg-arc source, the recently rediscovered terahertz spectral range is accessible even with a room temperature operated DTGS-detector.
Spectral Range Extension
The VERTEX 80/80v can optionally be equipped with optical components to cover the spectral range from the far IR, or terahertz, through to the near and mid IR and visible, and up to the ultraviolet spectral range. Range change and maintenance are easy with its pre-aligned optical components and the actively aligned UltraScan™ interferometer.
BMS-c: The high-precision beamsplitter exchange option BMS-c for the VERTEX 80v vacuum spectrometer is provided by Bruker.
Thus, the remotely controlled automatic exchange of up to four different types of beamsplitters under vacuum conditions became possible. Now, it is possible to measure the complete spectral range from the UV/VIS to the far IR/THz without the need to vent the spectrometer optics bench for manual beamsplitter exchange.
NEW: Bruker has extended the existing range of beamsplitters with a new broad band far IR/THz beamsplitter for the VERTEX 80/80v FTIR spectrometer series.
Specifically for research and development of semiconducting and additional inorganic materials, the new far IR solid state beamsplitter will provide extra values as it covers nominally the spectral range from above 900 cm-1 to appr. 5 cm-1 in one measurement, and connects the mid IR with the very long wave FIR/THz wavelength ranges.
The VERTEX 80 and the VERTEX 80v standard configuration provides apodized spectral resolution of better than 0.2 cm-1, which is adequate for most ambient pressure gas phase studies and room temperature sample measurements. A PEAK resolution of better than 0.06 cm-1 is available for advanced low temperature work, e. g. on crystalline semiconductor materials or gas phase measurements at lower pressure.
This is the highest spectral resolution obtained using a commercial bench top FTIR spectrometer. A resolving power (wavenumber ν divided by spectral resolution ∆ν) of better 300,000:1 is demonstrated by high resolution spectra in the visible spectral range.
The innovative optics design results in the most expandable and flexible R&D vacuum FTIR spectrometer available. With the evacuated optics bench, PEAK sensitivity in the far-, mid- and near-IR regions is obtained without the fear of masking extremely weak spectral features by air water vapor absorptions.
Excellent results, e.g. in the area of nanoscience research down to less than 10-3 monolayers, can be acquired with the VERTEX 80v vacuum FTIR spectrometer. There are almost no limitations with respect to flexibility.
Five beam exit ports on the right, front and left side and two beam input ports on the right and rear side of the optics bench are available. This enables simultaneous connection of, for instance, a synchrotron light source using the rear side input port, the PMA 50 polarization modulation accessory at the right side exit beam, a fiber optics coupling at the right front side port, a bolometer detector at the left front, and the HYPERION series FTIR microscope at the left side exit beam.
BRAIN: Bruker Artificial Intelligence Network
FTIR spectroscopy is made to be reliable, fast and easy even for improved R&D experiments with a network of intelligent functions, such as recognition of sampling accessories (AAR) and optical components (ACR), automatic set-up and check of measurement parameters, and the permanent online checking (PerformanceGuard) of the spectrometer functionality.
The VERTEX 80 Series are ideal instruments for demanding research and development applications.
External Accessories, Sources and Detectors
The VERTEX 80/80v spectrometers are equipped with two beam input ports and five beam exit ports, and offer the possibility to connect them, for instance, to external laser and synchrotron light sources.

These spectrometers offer the broadest spectral range from the UV/VIS region (50000 cm-1) to the FIR/THz region (5 cm-1), an unmatched level of flexibility, and the highest spectral and temporal resolution.
