Near-field microprobes · Field imaging

A new way
to see fields.

A camera shows you what a structure looks like. Our photoconductive microprobes show you what it does — the terahertz field itself, resolved to micrometres and picoseconds.

Near-field microprobes · Material mapping

A new way
to see materials.

Sheet resistance and carrier mobility, read from the transmitted terahertz pulse and mapped across the full wafer — no contacts, no Hall bars, no damage to the film.

What you can measure

Four ways to look closer.

One near-field platform, four measurement domains — from wafer characterization to buried-defect screening.

Thin-film inspection

Wafers, solar cells & 2D materials

Map sheet resistance and carrier mobility at micron-scale resolution — non-destructive, contactless probing of displays, flexible electronics and graphene.

Chip testing

Fault isolation & on-chip TDS

High-resolution time-domain reflectometry for fault isolation, package-level inspection and on-chip device characterization — sub-picosecond, contactless.

Chip & package inspection →
Volume screening

Defects in opaque materials

Inspect plastic laser welds, fiber-reinforced polymers and organic layers — detect micron-scale defects buried in visually opaque materials.

Application highlight

Watch ultrafast processes unfold.

Phenomena that take place in picoseconds, visualized in the near field with a TeraCube M2 imaging system. A new way to see real-world ultrafast electrodynamics.
