Unmatched Performance and versatility: introducing the new

Price Guide: POA

VERTEX 70 FT-IR spectrometer for demanding analytical and research applications.

The new VERTEX 70 is the first fully digital FT-IR spectrometer for demanding R&D applications.

Its innovative design results in the highest flexibility and highest performance. The data acquisition is based on free running delta-sigma ADC’s with 24-bit dynamic range, which are integrated into the detector preamplifier electronics.

This advanced DigiTect™ technology prevents external signal disturbance and guarantees the highest signal-to-noise ratio.

Wide Spectral Range

The VERTEX 70 can be optionally equipped with optical components to cover the spectral range from 30 cm-1 in the far IR, through the near IR and up to the visible spectral range at 25,000 cm-1.

With its pre-aligned optical components and the permanently aligned RockSolid™ interferometer, range change is easy and maintenance free.

Automatic Component Recognition

The sources, detectors and beamsplitters on the VERTEX 70 are electronically coded to be recognized by the instrument and the appropriate experimental parameters are automatically loaded.

The user doesn’t need to know which parameter set to load; it’s all done automatically. In addition, if two components are installed that conflict, the VERTEX 70 will recognize this and inform you about the mismatch.

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 70 is ready for operation.

The instrument has the ease of use and reliability of the multi-range power supply.

The Ethernet connection to the VERTEX 70 also offers the possibility to control the spectrometer via your intranet or the World Wide Web.

Spectral Resolution

The standard spectral resolution of better than 0.5 cm-1 is suitable for most applications for solid, liquid and even gaseous samples.

However, should the needs of your application change, the spectrometer can be upgraded to a boxcar resolution of 0.16 cm-1.


The innovative optics design of the VERTEX 70 results in the most flexible and expandable FT-IR spectrometer available.

With an easily maintained, sealed and desiccated optics bench, the highest available sensitivity in the mid-, near- and far IR regions can be obtained on a spectrometer requiring no purge gas or cooling water.

The VERTEX 70 offers outstanding 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 allows simultaneous connection of, for example, a Hg-arc source at the rear side, the new RAM II FT-Raman module at the right, a fibre optics coupling at the right front side, the HYPERION™ IR microscope at the left side. In addition, a FIR bolometer can be attached at the front-left port.

Rapid Scan / Step Scan

VERTEX 70 offers unsurpassed functionality, that utilizes OPUS version 5.5 for Rapid Scan and Step Scan time-resolved spectroscopy (TRS) with transient recorders.

In figure 1, a 10 nsec time resolved Step Scan emission of the switch-on of a NIR laser LED at 4 cm-1 spectral resolution is shown.

New QuickLock based accessories like the reflection/transmission (A510/Q-T) and the parallel beam (A480) unit make the VERTEX 70 unique with respect to the measurements of absolute transmittance values.

The achievable high scan speeds are among the many performance features that distinguish VERTEX 70 as a research grade FT-IR.
