PB7300-2000-T/R Two-Channel Transmission-Reflection System

Bakman Technologies' versatile PB7300-2000-T/R Spectroscopy Platform is designed for scanning complex compounds to precise specifications with greater accuracy and control. The PB7300 series is ideal 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 PB7300-2000-T/R can sweep from 100 GHz to over 1.8 THz in a single rapid scan with frequency resolution better than 0.25 GHz. Because it has two channels it can be configured to simultaneously measure both the THz transmission and reflection properties of a sample. The second channel allows a single system to collect sample information at various angles of reflection or scattering from the sample while continuously monitoring the transmission.

The PB7300 employs precisely tuned, fiber coupled, butterfly packaged semiconductor DFB lasers, an advanced photo-mixing source and detector, and sophisticated digital control hardware and software to provide a fully turnkey THz spectrometer. The highly efficient CW nature of the photo-mixing source puts all the THz power at the frequency of interest, yielding excellent dynamic range across the scan range of up to 70 dB Hz.

The fiber-optically-coupled source and detector heads are mounted on an adaptable optical bench and configured for simultaneous transmission and reflection measurements. They may also be detached from the processor unit and used with extended fiber optic cables to provide maximum measurement flexibility in a wide range of applications.
