Microprobe cantilever design:
|Max. spatial resolution||3 µm||20 µm|
|Photo-switch gap size||1.5 µm||2 µm|
|Dark current @ 1 V Bias||< 0.5 nA||< 0.5 nA|
|Photocurrent @ 1 V Bias||>0.2 µA||> 0.2 μA|
|Excitation wavelength||700 .. 860 nm||700 .. 860 nm|
|Average excitation power||0.1 .. 4 mW||0.1 .. 4 mW|
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.
