Custom configurable and offering the industry’s highest level of measurement stability, this attractively priced new system makes THz technology accessible for a multitude of users


TOKYO, Japan – April 14, 2014 – Leading semiconductor test equipment supplier Advantest Corporation (TSE: 6857, NYSE: ATE) announced today that it has started sales of a new terahertz optical sampling system, the TAS7400TS. The flexible design of the new system allows the user to freely configure the terahertz source and detector modules, creating unparalleled versatility for the user. This system can be paired with a variety of terahertz source modules covering three different spectral ranges within the terahertz frequency band.

The terahertz range of frequencies spans 0.1 ~ 10 THz on the electromagnetic spectrum. With recent advances in the stable generation and detection of terahertz waves, the technology is attracting widespread interest for non-destructive analysis and high-speed communication uses, while research into a whole host of further applications also gathers momentum.

Advantest’s new TAS7400TS optical sampling system meets this growing market’s need for stable, highly accurate terahertz measurement functionality at an affordable price point. A new addition to the company’s low-cost, multi-purpose terahertz spectroscopy TAS7400 Series, the system allows users to configure their own platform by connecting THz source and detector modules to the mainframe with optical fiber pigtails. The modules can be freely positioned, creating a flexible measurement area. In addition, accessories such as sample heating, cryostats or automated sample handling may be configured into the measurement environment, opening up new possibilities for terahertz researchers and developers of future applications for this technology.

Priced affordably, starting at ¥18 million, the TAS7400TS brings terahertz technologies within reach of many R&D researchers, creating a much broader user base, in a wide range of sectors, from pharmaceuticals and biotechnology to new materials R&D.

Product Features

  • Superior Measurement Reproducibility
    Like the TAS7500TS, Advantest’s high-end terahertz wave spectroscopy and analysis platform, the new system relies on a proprietary low-jitter fiber laser and unique analog signal analysis technology to deliver industry-best measurement stability. Measurements are reproducible to within ±0.03%.
  • Selection of Terahertz Source Modules Enables Wide-Spectrum Application Coverage
    Three separate source modules are available for TAS7400TS platform configuration. Each covers a separate waveband: 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). These modules are also interchangeable with the TAS7500TS platform.
