Introducing our new generation TeraSmart Systems with unparalleled performance

The TeraSmart, an established broadband terahertz spectrometer recognized for its compact design and reliability, has undergone remarkable advancements, setting a new standard for industrial performance.

The integration of our new groundbreaking TERA15 antenna modules with high-power capabilities has advanced the system’s already impressive performance to a new level, establishing it as a market leader in terms of THz power, dynamic range, bandwidth, flexibility, and customization. In addition to its user-friendly turnkey functionality, TeraSmart utilizes Menlo Systems’ cutting-edge fiber-based femtosecond laser sources with our proprietary figure 9® mode locking technology. The modular design, incorporating the ELMO OEM laser platform, enhances adaptability, enabling tailored configurations for seamless integration into both industrial and academic environments. Multichannel setups are possible, allowing for simultaneous measurements using multiple emitter/ detector pairs, all powered by a single femtosecond fiber laser oscillator. The incorporation of an intelligent TCP socket interface enables remote control, advantageous for non-destructive testing of hazardous samples, and smooth integration into manufacturing lines.

TeraSmart is a compact, turnkey, and integratable terahertz spectrometer designed for continuous 24/7 operation. Additionally, the high levels of attainable THz power expand the potential applications of THz spectroscopy and imaging, making previously unexplored and challenging applications (e.g., analysis of highly absorbing, thick, and biological samples with high water content) in the terahertz region more accessible than ever before. Furthermore, users of existing THz systems can seamlessly upgrade to the new high-power antennas.
