Spectroscopy Imaging Extension
Toptica Photonics AGRequest Info
Toptica Photonics AG has announced the Terahertz Imaging Extension for its time-domain spectroscopy platform TeraFlash.
Owing to the 0.1- to 5-THz spectral bandwidth of the TeraFlash, researchers can exploit the full potential that the combination of imaging and spectroscopic methods has to offer. The Imaging Extension uses two precise linear stages to scan a sample through the focus of the terahertz beam. The translational movement is synchronized with the delay-stage within the TeraFlash, speeding up the measurements significantly, allowing the system to acquire
complete waveforms for up to 16 pixels/s. The positioning accuracy is >200 μm over a 15- × 15-cm field of view.
With the help of alignment pins, users can quickly reconfigure the optics from a
transmission setup to a reflection geometry, and vice versa. Both versions feature a powerful software package that offers a choice of contrast parameters, including amplitude, phase, and layer thickness. In addition, users can filter the raw data both in the time-domain and frequency-domain, and generate amplitude and height profiles along arbitrary cross sections of the sample.
