The compact terahertz spectrometer TeraSmart integrates the latest achievements in broadband Terahertz Time-Domain Spectroscopy (THz-TDS) into an easy-to-use turnkey solution. It combines Menlo Systems’ figure 9® femtosecond fiber laser technology with our industry-proven THz components. The modular design enables flexible system configuration for integration into any industrial or scientific application, with custom fiber length to THz antennas and multibranch configuration options, enabling simultaneous measurements of several emitter/detector pairs using only one fs fiber laser oscillator.
