Terahertz technology is a pioneering approach to measurement and analysis that has drawn attention and investment across a range of fields. Because substances reflect or absorb terahertz radiation differently, according to their unique fingerprint spectra, it is ideal for spectroscopic analysis and non-invasive imaging applications. Advantest launched its first terahertz analysis system - the TAS7000 3D imaging analysis system - in April 2010, and now leads the industry in practical applications for terahertz technology, with a line-up of non-invasive analysis systems targeting various markets, such as pharmaceutical products.

Meanwhile, cutting-edge research employs terahertz analysis technology in combination with other lab equipment, such as cryostats and heaters, in the development of new materials and physical analysis. Laboratories require measurement equipment that is both highly accurate and easy to use. Advantest's new terahertz wave spectroscopy and imaging analysis platform meets these requirements, and is positioned to help researchers make gains in accuracy and R&D efficiency.

Featuring terahertz source and detector modules connected to the mainframe by optical fiber cables, the new platform enables free layout of the area to be measured. The platform may also be connected to other lab equipment, supporting a broad variety of R&D projects utilizing terahertz radiation.

With this new product, Advantest confirms its position at the forefront of applied terahertz technology and R&D.

Source modules convert laser pulses into terahertz waves. A separate module is available for each of three wavebands: the TAS1110 for 0.1 - 4THz (basic type), the TAS1120 for 0.03 - 2THz (low-frequency type), and the TAS1130 for 0.5 - 7THz (broadband type), with the TAS1130 possessing superior bandwidth coverage and spectral flatness.

The detector module samples the waves that are reflected by or pass through the sample under measurement. Each module is connected to the TAS7500TS by a 1.5 meter optical fiber cable, eliminating the need for complex adjustments, and enabling users to position the modules flexibly for best alignment with samples.
