TeraSysUltra Ultra Ultra Wideband Terahertz Time Domain Spectrometer - Terahertz Wave Spectrometer Product Description:

TeraSysUltra Ultra Ultra Wideband Terahertz Time Domain Spectrometer - Terahertz Wave Spectrometer is Rainbow Photonics' ultimate solution for terahertz spectroscopy and imaging based on organic crystals. It is a compact terahertz instrument that can perform real-time addressing, detection, analysis, and computation monitoring at terahertz frequencies. It is based on organic crystals and has the advantages of real-time acquisition (up to 4 spectra per second), high frequency resolution, compact structure, and easy installation. It can provide both transmissive and reflective solutions; Its operating frequency range is extremely wide, reaching 0.3-20Thz, covering high-frequency areas that conventional optical antennas cannot reach. TeraSys Ultra long bandwidth terahertz time-domain spectrometer is highly suitable for material spectral analysis in the terahertz range up to 20THz, and can be used for research in semiconductor materials, material detection, polymer biology, and terahertz imaging applications.

Rainbow Photonics is affiliated with the Nonlinear Optics Laboratory at ETH Zurich and was established in 1997. The company has developed a series of novel THz spectrometers based on the generation and detection of THz using nonlinear organic crystals, covering the high-frequency range that optical antennas cannot reach.

Typical time-domain spectrometer structure principle:

Different detection modes such as transmission and reflection can be used for different samples, testing requirements, and the interaction between terahertz waves and samples. Among them, the most common is the transmission mode. Figure 3 shows its structural device diagram.

working principle:

Terahertz time-domain spectrometer is a device that uses pulsed THz waves for spectral detection. It can simultaneously obtain amplitude and phase information of THz pulses during measurement. By performing Fourier transform on the time waveform, optical parameters such as absorption coefficient and refractive index of the sample can be directly obtained. It has high detection sensitivity and wide detection bandwidth, and is a very effective spectral testing method. Through its demonstration applications in the fields of basic scientific research and food and drug safety, it can drive its potential applications in biomedical, semiconductor materials, industrial processing, cultural relic detection, petroleum exploration and other fields.
