The new 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’ latest fiber-based femtosecond laser sources featuring our figure 9® mode locking technology with our industry-proven THz components. The modular design based on our OEM laser platform ELMO ensures a flexible configuration of the system to meet the needs for integration in any industrial or scientific environment. Custom fiber lengths to THz emitter and THz detector are available upon request. Moreover, multibranch configurations are possible, enabling simultaneous measurements of several emitter/detector pairs using only one fs fiber laser oscillator.

Rounding off the product, a smart TCP socket interface allows platform-independent remote control over Ethernet connections for seamless integration in existing experiments or in industrial nondestructive testing (NDT) environments. In short: A turnkey, OEM integrable THz spectrometer engineered for 24/7 operation.
