Terahertz System

The Menlo Terahertz product portfolio (THz, also known as millimeter waves) covers time domain solutions in traditional pump-probe configurations, as well as solutions for imaging. The products for the time domain are ideally suited for fingerprint spectroscopy whereas the imaging instruments find their use in quality control and inspection.

TERA K15

TERA ASOPS

Description
With the ASOPS technique, ultrafast data sampling is no longer limited by the natural restrictions of a mechanically moving optical delay unit. The novel TERA ASOPS high-speed THz time-domain spectrometer system is using this technique to temporally scan THz pulse traces at a revolutionary high rate. At the same time, it is extending the detection window to nanoseconds pushing the spectral resolution into the region of hundreds of MHz.
