TeraFlash pro
Versatile platform for time-domain terahertz spectroscopy
- New: High-power version, dynamic range up to 120 dB
- > 6 THz bandwidth
- Variable terahertz path length between 15 cm and 110 cm
- “Dual” version for 2 emitter/receiver pairs
The TeraFlash pro, a table-top time-domain terahertz platform, sets new standards in terms of dynamic range, bandwidth and measurement speed. By means of a highly to an advanced laser design and progress in photoconductive antennas, the system now achieves a peak dynamic range of up to 120 dB, and a bandwidth of more than 6 THz. Owing to a highly precise mechanical delay stage, the system acquires 60 traces/s @ 50 ps scan range, or 95 traces/s @ 20 ps. The new “Dual” version enables simultaneous operation of two emitters and/or two receivers.
