At Pittcon 2014, Bruker Corporation announces the world's first FTIR spectrometer which covers the complete mid and far Infrared/THz spectral ranges in one step with no gaps! The new wide range MIR-FIR DLaTGS detector is combined with the recently introduced wide range MIR-FIR beamsplitter offered for the Bruker VERTEX 70 series of research FTIR spectrometers to achieve unmatched spectral range. This new combination provides data collection from 6000cm-1 to 10cm-1 in one step for all types of transmittance, reflectance, and ATR measurements without the need of any beamsplitter or detector exchange.

The achievable spectral range of an FTIR spectrometer is defined by its source, beamsplitter, and detector combination. The lower limit of the spectral range is very dependent upon the beamsplitter, and is typically limited to 350cm-1 (KBr) or 200cm-1 (CsI). To extend the spectral range further into the far IR and THz spectral ranges one or more additional far IR beamsplitters and detectors are required and because of this the user has to manually open the access flap of the spectrometer optics bench. Now available for the first time, Bruker has developed a wide spectral range beamsplitter and detector which in connection with the standard IR source, enables access to the spectral range from 6000cm-1 down to 30cm-1 in one step for all types of transmittance, reflectance and ATR measurements. These new optical components complement the automatic beamsplitter changer unit BMS-c and detector switching option already available for the VERTEX 80v high end research FTIR spectrometer.

When the VERTEX 70v vacuum spectrometer is equipped with these new wide range optical components, the spectral range is extended down to 10cm-1 utilizing the external water cooled mercury arc high power lamp and automatic source switching.

The extension of the mid IR towards the far IR spectral range below 400cm-1 is of general interest for molecular vibrational analysis for inorganic and organometallic chemistry as well as for geological, pharmaceutical, and physical applications. The ATR measurement of Ascorbic Acid shown here demonstrate that with the Bruker VERTEX 70 or VERTEX 70v FTIR spectrometers, the new wide band beamsplitter and new DLaTGS detector, yield a spectral range from 4000cm-1 to 30cm-1 in a single very convenient data acquisition.
