Customer survey: Prize winner

We would like to thank all the participants of our recent Terahertz technology survey. The lucky winner of the Lenovo Miix 310 convertible PC who has been drawn by our lottery volunteer is Mrs. Jannika Lauth from TU Delft.


Product news: First near-field probe for reflection-mode measurements

So far, microprobes from the TeraSpike product series have been solely designed for THz detection or generation purposes. The new TeraSpike probe TD-800-TR.5 comes with a pair of closely spaced photoconductive THz antennas. While one antenna is used as a THz pulse generator, the other antenna works as the detector.
