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. For further information please take a look at our brochure (PDF file, 2 MB) and FAQ section.
