VERTEX 70v FT-IR Spectrometer

VERTEX 70v offers unmatched performance and versatility for demanding analytical and research applications. Its innovative design results in the highest flexibility and highest performance. The data acquisition is based on two channel deltasigma ADCs with 24-bit dynamic range, which are running in parallel and integrated into the detector preamplifier electronics. This advanced DigiTectTM technology prevents external signal disturbance and guarantees the highest signal-to-noise ratio.

Vacuum Optics

With the evacuable optics bench of the VERTEX 70v vacuum FT-IR spectrometer, PEAK sensitivity in the mid-, near and far IR/THz regions are obtained without the fear of masking very weak spectral features caused by water vapor or CO2 absorptions. Outstanding results, e.g. in the area of nano-science research down to sub-monolayers, can be obtained.


Bruker FM FIR-MIR Spectroscopy

The unique Bruker FM technology provides the possibility to acquire a complete far and mid IR spectrum from 6000 cm-1 to 50 cm-1 in a single step measurement with no need to change any optical component.


Wide Spectral Range

The VERTEX 70v can optionally be equipped with optical components to cover the spectral range from 10 cm-1 in the far IR/THz, through the mid and near IR up to the VIS/UV spectral range at 28,000 cm-1. With its pre-aligned optical components and permanently aligned RockSolidTM interferometer, range change is easy and maintenance free.

Artificial Intelligence Network

An assembly of great functions such as recognition of sampling accessories and optical components, automatic set up and check of measurement parameters makes FT-IR spectroscopy easy, fast and reliable. In addition, the permanent online check of spectrometer components keeps fault diagnostics and maintenance simple. A full suite of software tools ensures this functionality.


Plug & Play: Easy Set Up

All over the world, no matter where you are, plug in the power cord and the Ethernet connection, and the VERTEX 70v is ready for operation. The Ethernet connection to the VERTEX 70v also offers the possibility to control the spectrometer via your network or the World Wide Web.

The VERTEX 70v is the ideal instrument for demanding research and development applications.
