Terahertz wave spectroscopy and imaging analysis platform
The TAS7500TS is a Terahertz (THz) analysis system consisting of an optical fiber laser module and a data acquisition module, which are core parts of our terahertz spectroscopy system (TAS7500SP). Users complete the THz measurement system setup by simply connecting one of Advantest's THz source modules (TAS1110/TAS1130) and a detector module (TAS1230; sources and detectors sold separately). Flexible source selection and source/detector placement allows the user to generate customized experimental configurations.
Supports a wide range of terahertz research and applications
Super-high-speed terahertz optical sampling measurement (1msec/scan)
Fiber pigtails enable flexible layout of THz source/detector modules and optical sampling system
Features
1msec/scan super-high-speed terahertz optical sampling measurement (TAS7500TS)
Flexible configuration of THz source/detector modules and optical components
Up to 4 meter optical path length
Configure with up to 2 different THz source and 2 detector modules (Optional)

Terahertz Optical Sampling System TAS7500TS
High-end system with fast analysis & best-in-class measurement accuracy
The system uses two channels of ultra short pulse lasers (1.55 ?m) with either biased output (for THz generation) or signal input (for THz detection). Advantest's unique optical sampling method, utilizing phase-modulated dual-laser-synchronized control technology without a mechanical optical delay line, enables extremely high speed terahertz spectroscopy.
