Menlo Systems introduced its Tera ASOPS tool, which combines ASynchronous OPtical Sampling (ASOPS) technology with the latest broadband THz devices to form a turn-key terahertz time-domain spectroscopy system where scanning range and speed are no longer limited by mechanically moving parts. A detection window of 10ns is available for measurements at a high rate, while the spectral resolution is in the region of hundreds of MHz.

Fibre coupled high-power THz modules and high-transmission low-loss polymer optics guarantee broadband performance, easy alignment and long-term stability of the THz path. Despite its complexity, the Tera ASOPS provides user-friendly operation and measurement software. A fast TCP socket interface allows remote control and high-speed data transfer over network. 

The range of applications for the Tera ASOPS can be extended by adding laser output ports at 1,560 and/or 780 nm wavelengths, turning the system into a stand-alone tool for ultrafast optical spectroscopy.
