Description
verTera THz extension
In addition to the unmatched VERTEX 80v FT-IR performance and flexibility, the verTera extension provides access to the single digit wavenumber regime and highest resolution without the need of cryogenically cooled components. This would be impossible for a conventional FT-IR setup since bolometers at liquid Helium temperatures would be required. verTera offers a lot of exciting possibilities:
- Integrated state of the art cw THz technology
- Spectral range down to 3 cm-1 (< 90 GHz)
- Unique spectral resolution < 0.0007 cm-1 (< 20 MHz)
- Same sample compartment & accessories for FT-IR and THz
- Highest THz performance by vacuum & unique THz algorithm
- FT-IR and THz controlled via powerful OPUS software
State of the ART CW THz Technology:
verTera makes use of high precision semiconductor based photomixers, converting near infrared laser light into THz radiation. Source and detector are integrated into the VERTEX 80v beam path and the class 1 NIR laser radiation is connected via fiber and vacuum tight feedthrough.
Highest THz performance by vacuum:
Vacuum operation eliminates unwanted atmospheric interferences and provides utmost stable conditions, resulting in significantly higher THz performance.
Highest Resolution by Unique THz Data Processing:
The standard approach to extract just the extrema of the oscillating photocurrent signal strongly degrades spectral resolution. Only verTera uses a unique algorithm achieving a significantly better effective spectral resolution < 0.0007 cm-1 (< 20 MHz) similar to the applied THz step size.
Applications
The increased spectral range and improved THz resolution provided by verTera add valuable information for many applications, e.g.: polymorphism, polymer research, high resolution gas spectroscopy, crystal structure (solid state & semiconductor physics) and pharma or drug related research.
