Our portfolio of TeraSpike probes for reflection-mode measurements has been extended by two further models: the TSR.75 and the TSR-TT.75. The new series of Terahertz transceiver probes now serves a wider range of application scenarios, starting with volume inspection (TR.5), near-surface volume inspection with increased spatial resolution (TSR.75) and surface scanning with maximum spatial resolution (TSR-TT.75). While basically all TR series probes can be used also for transmission-mode operation, the TSR-TT.75 is best suited for this mode in respect of highest spatial resolution.

The TR series is taking advantage of Protemics´ proprietary “wave-trap” design for the suppression of probe-internal reflection signals as well as the XR-type flexible cantilever design for increased mechanical robustness. Our transceiver probes provides access to sub-wavelength-resolution and shortest THz transmissions paths.

TR series probes are based on the patent applications DE 10 2009 000 823.3, DE 10 2014 015 516.1, DE 10 2016 002 733.9, DE 10 2020 002 735.0.

The new TeraSpike model TR.5 comes with a pair of closely spaced photoconductive THz antennas offering new means for high-performance near-field measurements in reflection-mode. While one antenna is used as a radiation pulse generator, the other antenna is used as the detector. The slim transceiver probe is taking advantage of Protemics´ proprietary “wave-trap” design for the suppression of probe-internal reflection signals as well as the XR-type flexible PET cantilever design for increased mechanical robustness. In contrast to standard reflection-mode approaches based on far-field emitter/detector components the new near-field transceiver probe provides access to sub-wavelength-resolution and shortest THz transmissions paths.
