PB7220-2000-T Portable Frequency Domain Terahertz Spectrometer DATASHEET | MAY 2014 TERAHERTZ SYSTEMS Compact, Portable Terahertz Spectroscopy System EMCORE’s versatile PB7220-2000-T Spectroscopy Platform is designed for scanning complex compounds to precise specifications with greater accuracy and control. 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 can sweep from 100 GHz to over 1.8 THz in a single rapid scan with frequency resolution better than 0.25 GHz. 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 room temperature solid-state homodyne detection technique eliminates 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 ratios across the scan range of up to 70 dB Hz. Applications Threat Signature Characterization o Explosives o Biologicals o Chemicals Unlike time-domain systems requiring expensive mode-locked lasers, the tunable semiconductor laser diodes in the PB7220 can support linear scans or can ‘frequency hop’ between frequencies of interest to scan specific regions of the spectrum with varying degrees of resolution. The fiber-optically-coupled source and detector heads are mounted on a rail system and configured for transmission 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. Microwave and THz Spectroscopy Performance Highlights Materials Characterization Features Parameter Full Turnkey System: Arrives Configured and Ready to Start Making Measurements Extremely Economical: A Fraction of the Cost of Previous THz Systems Portable: Configurable with Built-in Li Ion Battery with up to 12 hours of Continuous Use Compact: Under 23 cm x 23 cm x 8 cm (9″x 9″ x 3″) and Less than 7 kg with case Continuous Rapid Scanning From 100 GHz to over 1.8 THz Fiber Optic Coupled THz Source and Detector Heads Min Typical Max Units System Bandwidth 1700 1850 2100 GHz Spectral Purity 0.010 0.015 0.025 GHz Frequency Resolution 100 1000 5000 MHz Dynamic Range @ 100 GHz 65 70 75 dB Hz Dynamic Range @ 1000 GHz 40 55 60 dB Hz Dynamic Range @ 2000 GHz 30 40 45 dB Hz THz Beam Diameter @ 500 GHz THz path length Tuning speed Electronic Chopping Frequency mm (FWHM) 6 10 25 - 10 GHz/sec 6000 Hz Integrated Lock-in Detection Room Temperature Solid State Detection: No Cryogenics Required Shipped in Custom Travel Case OEM Version with Quantity Pricing Available | REV 2014.05 cm Please see last page for Regional Sales Contact Information Information contained herein is deemed reliable and accurate as of the issue date.

PB7220-2000-T Portable Frequency Domain Terahertz Spectrometer TERAHERTZ SYSTEMS DATASHEET | MAY 2014 Graphical User Interface The PB7220 includes highly functional software for Windows 7 PCs. Besides being able to control the frequency of the system with the Dwell or Scan, it is now also possible to do averaging, background subtraction, normalization and smoothing all from the same interface. The calibration files are installed into the PB7220, and if a new computer is connected to the PB7220, the calibration files are automatically downloaded to the computer. This makes it easy to move the PB7220 to different computers.
