BAKMAN便携仪太赫兹频域光谱仪
PB7220-1500-PM Single-Channel System with Phase Control
Features
- Full Turn-Key System: Arrives Configured and Ready to Start Making Measurements
- THz phase is continuously adjustable during operation
- Phase control is achieved optically and without the use any moving parts
- Standard 1 RU enclosure with optical and electrical connections in the back
- Fiber Optic Coupled THz Source and Detector with 5 meter tethers
- Integrated Lock-in Detection with reference signal output
- Room Temperature Solid State Detection: No Cryogenics Required
Bakman Technologies' versatile PB7220-1500-PM Spectroscopy Platform is designed for scanning complex compounds to precise specifications with greater accuracy and control than comparable systems. The PB7220 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 PB7220-1500-PM can sweep from 100 GHz up to 1.5 THz with a frequency resolution better than 0.25 GHz and real-time phase adjustment of better than 1 degree.
The PB7220 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 photomixing 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 PM unit includes a custom designed and manufactured optical lithium niobate phase modulator which allows complete control of the instantaneous THz phase.
The fiber-optically-coupled source and detector heads are mounted on a rail system and configured for transmission measurements. They are coupled to the rack mounted control unit with 5 meter optical and electric tethers that allow a great range of flexibility.

PB7220-2000-T/R Two-Channel Transmission-Reflection System
Bakman Technologies' versatile PB7220-2000-T/R Spectroscopy Platform is designed for scanning complex compounds to precise specifications with greater accuracy and control. The PB7220 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 PB7220-2000-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 PB7220 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.

The PB1319 family of terahertz photomixers provide the proven high performance of Low Temperature Grown Gallium Arsenide semi-conductor technology in a practical, rugged, fiber-coupled package. These photomixers are built to ISO:9000 manufacturing standards and employ fully laser welded assemblies with an integrated optical lens for the pump lasers as well as a THz Silicon lens. The PB1319 photomixers have a proven record of reliability even down to temperatures of 4.5 Kelvin.
PB1319 photomixers are commonly employed in coherent photomixing systems for both the production and detection of terahertz radiation. They are available in several configurations as well as in custom mounts or configurations and are laser welded assemblies with an integrated optical lens as well as a collimating THz Silicon lens.
