THz Emitter/Detector Mounting Stage

Separately from THz emitter and detector EKSPLA provides convenient mounting stage compatible with both devices. It contains lens, mounted on adjustable XY holder, compact stage for shifting lens along optical axis and rail, on which both: lens and emitter/detector are mounted.

This helps with pump beam guiding to the gap between electrodes located on photoconductive antenna, as well as adjusting beam diameter on active surface. Convenient fixing screws allow fast mounting and removing each part of this simple setup.

THz Spectroscopy Kit

EKSPLA “THz spectroscopy kit” contains all the components necessary to build THz-TDS system. The standard kit consists of photoconductive antenna THz emitter and detector, pump laser beam guiding optics, motorized delay line with controller, bias power supply TMS-100, THz beam guiding optics, sample holder and lock-in amplifier. All components are assembled on the baseplate of 60×80 cm dimensions.

Four standard configurations are available, optimized for transmission, reflection, imaging or pump-probe measurement. All can be easily interchanged and modified. Any other optional configuration can be ordered initially or as a future upgrade. THz spectroscopy kit is controlled by LabView™ based dedicated software.
