Terahertz Spectroscopic System TAS7400
Low-cost, multi-purpose terahertz spectroscopic system to meet diverse applications
Key Features
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.
Low-cost, all-purpose THz spectroscopic system offers superior spectroscopic performance
Compact desktop form factor
THz spectroscopic analysis in a range of frequencies (0.03–7 THz)
Transmission, reflectance, ATR (Attenuated Total Reflection), and transmission polarization measurement modes support spectroscopic analysis of a wide variety of materials
Dry air filter unit attached, so that measurements will be unaffected by water vapor absorption
A full range of holders and cells to handle aqueous solutions, powders, and other types of samples
Superior Performance
High Troughput
Advantest’s proprietary sampling
technique—an electronically
controlled sweep method—delivers
higher throughput than any previous
system.
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)
measure-ments to within ±0.03 % (typ.).
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.
