It is well-known, that VERTEX 80v research FTIR spectrometers can access the THz spectral range down to 5 cm-1 (approx. 0.15 THz) and hold the record for the broadest achievable spectral range from UV/Vis to THz using FTIR technique. The vacuum spectrometers VERTEX 80v and VERTEX 70v can reach 10 cm-1 using the room temperature FIR DTGS detector combined with the external Hg arc source and the appropriate beamsplitters. The superior instrument performance and sensitivity with this configuration are sufficient for most chemical or physics applications in FIR region. Furthermore, in some very demanding experiments requiring utmost sensitivity in the FIR/THz region to detect extremely weak spectral features, or for measurements requiring access down to a few wavenumbers, liquid Helium cooled bolometers can be applied additionally.Outstanding FIR/THz spectral range specification of VERTEX vacuum spectrometers
To reach the spectral limits, highest sensitivity or resolution in the FIR/THz region liquid Helium cooled bolometers are often required as detector. Since liquid He is very costly, in some regions even not available at all, the handling of this cryogen liquid demands skilled operators and significant set-up time, it is increasingly considered as bottle neck by many researchers. Alternative dry pulse tube cooled bolometers require long evacuation and cool down time (approx. 3-4 h), may create artifacts by potentially harmful vibrations and are still quite expensive.
Now these limitations are overcome by the new and unique verTera Terahertz extension for the VERTEX 80v vacuum spectrometer. With verTera functionality the famous VERTEX 80v becomes the world’s first and only combined FTIR/continuous wave THz spectrometer with amazing possibilities. A spectral range down to 3 cm-1 (0.09 THz) can be covered without the need of any cryogenically cooled components.
