  • Precise Placing Through Spacer
  • Purging Access


Menlo Systems provides a plug-in, compact terahertz reflection head with integrated optics for high-performance measurements with fixed working distance of 4“ (~10 cm). The reflection head is suitable to all Menlo Systems terahertz timedomain spectrometers (THz-TDS) and contains 4 off-axis parabolic mirrors with focal lengths of 2“ and 4“, respectively. The strength of this module lies in the uncompromised performance providing a bandwidth of >6 THz in combination with all Menlo Systems’ THz-TDS systems. A spacer with a length identical to the working distance offers the best ease of use for placing the sample in the focus. It can be detached for applications demanding contact-free measurements. Rounding this unit up, an alignment target serves to adjust the reflection head and integrate it easily into the measurement setup.
