In addition to custom-specific microprobes (please inquire) the following standard models are offered for pulsed excitation:
Electrical connection is done through a compact coaxial SMP plug. We recommend the use of a low-noise current amplifier with 107-108 V/A amplification (e.g. DLPCA200) and high-grade connection cables (e.g. our TS Cable) for optimum operation.
TeraSpike TD-800-X
The microprobes from the X-series are sensitive to electric vector field-components oriented in transversal direction to the probe-tip axis as defined by the x-axis direction in the upper illustration. The model TD-800-X-HR offers highest spatial resolution. The model TD-800-X-HRS is characterized by highest sensitivity for f = 0.5 THz - 1.3 THz and 20 µm spatial resolution.

Z-series microprobes are sensitive to THz field components oriented in longitudinal direction to the probe-tip axis as defined by the z-axis direction in the upper illustration. The N-option does not include a resonant antenna element and provides a somewhat higher bandwidth. The A-500G-option includes an antenna element for enhanced sensitivity around 0.5THz.
Each probe is individually tested and comes with a manual & test certificate.
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.
Type | -TR.5 | |
Dark current @ 1 V Bias | < 1.5 nA | |
Photocurrent @ 1 V Bias | > 0.5 µA | |
Excitation wavelength | 700 .. 860 nm | |

Connection type | 2x SMP |

The TeraSpike TD-1550-Y-BF is a microprobe emitter based on patent pending design (DE 10 2013 020 216.7) for the bias-free surface-near excitation of Terahertz pulses on planar waveguides, metallic surfaces or meta-materials. The optically generated THz field is polarized in y-direction.
Configuration: THz pulse generation on a thin-film microstrip line using the bias-free TeraSpike emitter microprobe. For on-chip contact-free THz field detection a second TeraSpike probe from the TD-800-X or Z series can be applied.
