Trek offers a wide variety of probes to accurately measure the surface potential up to 20kV and of spot sizes as small as 1mm.
Range features
A high level overview of what this range offers
- Different aperture sizes based on the needed spatial resolution and noise performance requirements
- End view and side detectors to accommodate installation constraints
- High temperature and vacuum options
Probe selection – what to consider
Aperture size – depending on the spatial resolution and the noise performance requirements, we offer different aperture sizes. Smaller apertures provide a finer spatial resolution, larger apertures provide a lower noise. Also, the measurement spot size depends on the distance of the probe to the sample.
End view and side view – select from end-viewing or side-viewing detectors depends on your measurement setup.
High temperature – high-temperature probes that operate up to 100°C.
High resolution – high-resolution probes that measure spot sizes down to 0.8mm.
