Microprobe cantilever design:
|Max. spatial resolution||8µm||8µm|
|Photo-switch gap size||2µm||5µm|
|Dark current @ 1 V Bias||< 0.4 nA||< 0.4 nA|
|Photocurrent @ 1 V Bias||>0.1 µA||> 0.2 μA|
|Excitation wavelength||700 .. 860 nm||700 .. 860 nm|
|Average excitation power||0.1 .. 4 mW||0.1 .. 4 mW|
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.
