PB7200 Portable Frequency Domain Terahertz (THz) Spectrometer
EMCORE’s versatile PB7200 Spectroscopy Platform is designed for scanning complex compounds to precise specifications with greater accuracy and control.
Designed for THz researchers and application developers who need to study the properties of materials at THz frequencies with high-resolution, but who don’t want to design and build their own high-resolution THz spectroscopy system. The PB7200 can sweep up to 2.0 THz in a single rapid scan with frequency resolution better than 0.25 GHz.
The PB7200 employs precisely tuned semiconductor DFB lasers, advanced photo-mixing source and detector, and sophisticated digital control hardware and software to provide a fully turnkey portable THz spectrometer system. The room temperature solid-state homodyne detection technique results in a system NEP of 10-12 W/Hz without the need for cryogenics. The highly efficient CW nature of the photo-mixing source puts all the THz power at the frequency of interest, yielding excellent signal-to-noise ratio.
And, unlike prior time-domain systems requiring complicated mode-locked lasers, the tunable semiconductor laser diodes in the PB7200 can support linear scans or can at a specific frequency of interest to scan specific regions of the spectrum with varying degrees of resolution. The separate source and detector heads may be configured to make measurements in transmission or reflection configurations.
