Terahertz optical sampling system for R&D lab applications
Advantest has introduced 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. 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 interest for non-destructive analysis and high-speed communication uses, while research into a host of further applications also gathers momentum, says Advantest.
The TAS7400TS aims to provide stable, highly accurate terahertz measurement functionality at an affordable price. An addition to the Advantest’s low-cost, multi-purpose terahertz spectroscopy TAS7400 Series, the system is said to allow 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 for a flexible measurement area. In addition, accessories for sample heating or automated sample handling may be configured into the measurement environment, which could open up new possibilities for terahertz researchers and developers of future applications for this technology.
The TAS7400TS is intended to bring terahertz technologies within reach of many R&D researchers, creating a broader user base in a wide range of sectors, from pharmaceuticals and biotechnology to new materials R&D.
Like the TAS7500TS, Advantest’s high-end terahertz wave spectroscopy and analysis platform, the new system relies on a low-jitter fibre laser and analogue signal analysis technology to deliver measurement stability. Measurements are reproducible to within ±0.03%.
Three separate source modules are available for TAS7400TS platform configuration. Each covers a separate waveband: 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). These modules are also interchangeable with the TAS7500TS platform.
