Product Introduction
Shanghai Yichi Optoelectronics has launched a laboratory level terahertz time-domain spectrometer system, with Toptica's femtosecond laser and Tetechs' photoconductive antenna as the core components. The system allows experimenters to complete terahertz time-domain transmission and reflection spectrum testing in the same system. This terahertz time-domain spectrometer device has been widely tested and proven.
1) Femtosecond laser; 2) THz transmitting antenna; 3) THz focus "transmission spectrum test"; 4) THz focus "reflectance spectrum test"; 5) HRSi beam splitter; 6) Motor delay line; 7) THz detection antenna
