Bruker Corp., Madison, Wis., announces the Vertex FM, the world’s first FTIR spectrometer that covers the complete mid and far Infrared/THz spectral ranges in one step with no gaps. In addition, the company offers a new wide-range MIR-FIR DLaTGS detector, which provides data collection from 6000cm-1 down to 50cm-1 in one step without the need for any beamsplitter or detector exchange.
The achievable spectral range of an FTIR spectrometer is defined by the intersection of the efficiency ranges of the source, beamsplitter, and detector. 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. Because of this the user has to manually open the access flap of the spectrometer optics bench.
Now available for the first time is Bruker’s Vertex FM feature, which combines the unique wide spectral range beamsplitter, the new wide range detector, and the standard IR source. These cover the spectral range from 6000cm-1 down to 50cm-1 in one step for all types of transmittance, reflectance, and ATR measurements. The unique Vertex FM technology complements the automatic beamsplitter changer unit BMS-c and detector switching devices that are available for the Vertex 80v high end research FTIR spectrometer.
When the Vertex 70v vacuum spectrometer is equipped with the Vertex FM spectroscopy option, the spectral range is extended down to 10cm-1 utilizing the external water cooled mercury arc high power lamp and automatic source switching.
