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:
The TeraCube Scientific is a fully automated THz near-field scanning system to be operated in an optical laboratory surrounding. It can be driven by an existing fs-laser source with suitable specifications or extended with a new laser source. The system enables time-domain measurements of THz field distributions in a controlled distance of a sample surface. The system provides broadband THz pulse excitation and transmission through planar samples as well as spatially and temporally resolved detection of the transmitted pulses in the surface near-field using Protemics proprietary TeraSpike near-field microprobes.
