TeraFlash smart

Ultrafast Time-Domain Terahertz Platform

  • Fast measurements of complete terahertz waveforms: 1600 pulse traces / sec
  • Proprietary and patented ECOPS technology
  • Robust design, no mechanical delay line
  • Time-domain dynamic range: > 50 dB single-shot, > 80 dB in 1 s
  • Spectral bandwidth: 3 THz single-shot, 4 THz in 1 s

TOPTICA’s TeraFlash smart utilizes a proprietary scheme dubbed ECOPS ("electronically controlled optical sampling"). The system comprises two synchronized femtosecond lasers, eliminating the need for a mechanical delay. This results in extremely high measurement speeds: the TeraFlash smart acquires 1600 complete terahertz waveforms per second, enabling terahertz-based thickness gauging at unprecedented speed. The system thus lends itself to measurements on rapidly moving samples, e.g. conveyor belts, papermaking machines, or extrusion lines.
