The verTera extension is offered in three different versions that access different spectral regimes but all achieving the same unique spectral resolution of better than 0.0007 cm-1 (20 MHz). An overview about existing versions is given in the table below. The spectral range above the given upper limit can be covered without gap by the FTIR mode of the VERTEX 80v using room temperature components.
Bolometers are well-proven high sensitivity THz detectors down to
5 cm-1
but the required liquid Helium adds costs, demands expertise and is in
some regions not available at all. Alternative dry e.g. pulse tube
cooled bolometers are rather costly, may cause harmful vibrations and
require several hours cool down time. The verTera extension is ready at
the push of a button, creates no nameable operation costs and can
achieve a superior lower spectral limit and resolution.
| Version | Spectral Range | Spectral Resolution |
| verTera-B | 3 to 40 cm-1 (90 GHz to 1.2 THz) | <0.0007 cm-1 (< 20 MHz) |
| verTera-BM | 13 to 50 cm-1 (0.4 to 1.2 THz) | <0.0007 cm-1 (< 20 MHz) |
| verTera-BS | 27 to 60 cm-1 (0.8 to 1.2 THz) | <0.0007 cm-1 (< 20 MHz) |

太赫茲波，又稱遠紅外輻射波，具備非常卓越的特性。許多常見的材料和組織對于太赫茲波都是半透明的，并表現出“太赫茲特性”，使得利用太赫茲波鑒別和分析樣品成為可能。太赫茲光譜技術具備非常廣泛的應用前景，比如......
太赫茲波是指頻率介于0.1~10THz之間的電磁波，其波長范圍為0.03~3mm。太赫茲波在電磁波譜中的位置位于微波和紅外輻射之間，故對其研究手段由電子學理論逐漸過渡為光子學理論。20世紀90年代以前......
