TAS7400 Series detail information｜Terahertz Systems

Low-cost, multi-purpose terahertz spectroscopic system to meet diverse applications

Superior Performance

High Throughput

Advantest's proprietary sampling technique-an electronically controlled sweep method-delivers higher throughput than any previous system.

Throughput comparison. TAS74000 takes 200 millisecond and TAS7500 takes 8 millisecond per scan, compared to 16 seconds for previous systems.

Highly stable measurement reproducibility

Advantest's proprietary low-jitter optical fiber laser technology and independently developed analog signal analysis technology enables highly stable reproduction of refractive index (phase) measurement to within ±0.03 % (typ.).

$The refractive index reproductivity for silicon is within plus/minus 0.03%.$

Wideband THz spectroscopic analysis

The TAS7400SP, along with two specialized spectroscopic analysis systems—the TAS7400SL and the TAS7400SU—provide bandwidth coverage required to serve a broad array of applications.

TAS7400SL for Low-frequency spectroscopy 0.03 to 2 THz.
TAS7400SP for Standard-band spectroscopy 0.1 to 4 THz.
TAS7400SU for Wide-band spectroscopy 0.5 to 7 THz.

The TAS7400 product line offers a series of low-cost, all-purpose spectroscopic systems that enable spectroscopic measurements using terahertz (THz) waves. The tools are capable of performing non-destructive analysis on a wide variety of sample types, making it applicable to a broad range of fields from life sciences to electronics, where precise chemical and material characterization is critical. The systems are ideal for settings ranging from basic research to product development, as well as for manufacturing and quality control, and employ easy-to-use spectroscopic methods that do not require specialized knowledge of THz wave generation or optics.

Measurement Accessory Supporting a Wide Range of Spectroscopy Needs

Transmission accessories can be used to measure samples for maximum sensitivity. Reflectance accessories can be used to measure density and samples with internal layers. ATR accessories can be used to measure samples with high absorbance, powders. Transmission polarization analysis accessories can be used to measure polarization characteristics. Transmission polarization analysis accessories can be used to analyze polarization properties

Thermal Control Accessory (Option for Transmission Accessory)

This accessory enables analysis of very high / very low temperature samples using the transmission accessory.
Two models are available, with operating ranges of -10 to +80°C (TAS1020) and room temperature to +300°C (TAS1030).
Dry air purge function prevents condensation at low temperatures.
