Scanning systems

Our scanning system solutions are the ideal modular platform for THz near-field imaging applications of any kind. All system components are optimized for the utilization of TeraSpike microprobes at maxmimum performance.

Standard scanning system configurations may be combined with a suitable laser systems on customer side or can be extended with a new laser source for optical excitation.

Scanning systems are designed for applications such as:  

  • THz Metamaterial research and sensing application
  • Semiconductor wafer inspection
  • Sheet resistance imaging
  • Graphene analysis
  • THz device characterization
  • Microstructure analysis
  • Non-destructive testing

 

TeraCube Scientific

TeraCube Scientific

THz near-field scanning system

The TeraCube Scientific and the new TeraCube Scientific M2 are fully automated THz near-field scanning systems to be operated in an optical laboratory surrounding. Both systems enable time-domain measurements of THz field distributions in a controlled distance to a sample surface.  Protemics proprietary TeraSpike near-field microprobes are used to image broadband THz pulses transmitted through planar samples.

Key features:
  • High-speed data acquisition for continuous move scanning through synchronized motion-control and real-time position detection
  • Optical sample topography detection for adaptive THz surface scanning at constant microprobe/surface-distance on structured or bended samples
  • Linear polarized and rotatable THz emitter for polarization-dependent measurements
  • High performance THz emitter/detector components plus high dynamic range Lock-in detection for outstanding signal quality
  • Integrated CCD camera module for monitoring of microprobe tip and sample position
  • System control and measurement automation software with easy to operate graphic user interface readily installed on included PC unit
  • Software-implemented alignment monitoring function and system health check electronics
  • Software assisted microprobe-tip to sample surface approximation
  • Time-domain signal preview mode for fast optical alignment alignment
  • Data-export as plain-text or Matlab-compatible format
  • System housing for laser and dust protection
  • Open extendable lab-type system platform
