X-series microprobes are sensitive to THz field components oriented in transversal direction to the probe-tip axis as defined by the x-axis direction in the upper illustration. The HR-option does not include a resonant antenna element and provides a somewhat higher bandwidth. The HRS-option includes an antenna element for enhanced sensitivity around 1 THz.  

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.
