Microprobe cantilever designs:
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.
