Imported Terahertz Spectral Imaging

1 TAS7400TSTerahertz Spectral ImagingIntroduction to Sampling Platform

The system uses two ultra short pulse lasers (1.55 μ m) for bias output (terahertz wave generation) and signal input (terahertz wave detection). Based on Advantest's TAS7500TS terahertz spectroscopy system, TAS7400TS has higher measurement accuracy and cost-effectiveness in the industry.

2、 Suitable for various terahertz research and applications

• Ultra high speed terahertz optical sampling and measurement function up to 1ms

• Through fiber optic connections, terahertz source/detector modules and optical components can be flexibly configured

The TAS7400TSTerahertz Spectral ImagingSampling Platform Product Features

• Ultra high speed terahertz optical sampling measurement: 1mS/single scan (TAS7500TS);

• Flexible configuration of terahertz source/detector modules and optical components;

• A total optical path length of 4 meters;

• Configure 2 different THz light sources and 2 detector modules (optional);

• Covering low-frequency, standard, and broadband terahertz wave detectors;

4、 Terahertz source parameters

Module TAS1110 (Standard Type: 0.1-4 THz)/TAS1120 (Low Frequency Type: 0.03-2 THz)

Easy to use all-in-one terahertz source; The photoconductive antenna and the ultra hemispherical silicon lens are contained within a compact housing connected to the fiber optic tail.

Terahertz waves generated by 1.55 μ m ultra short laser pulses

Suppress the amplitude changes of terahertz waves caused by temperature fluctuations through a current monitor and a thermistor embedded in the bias circuit.
