PB7200 Terahertz Spectrometer

Portable Frequency Domain Terahertz Spectrometers

Bakman Technologies is pleased to announce the acquisition of Emcore’s Advanced Photonics business including the terahertz technology. This acquisition includes all the inventory, equipment, key personnel and intellectual property related to the terahertz product line. It also includes continued access to Emcore facilities and services.

Emcore entered the field of terahertz technology in 2004 with the release of the benchtop PB7100. The PB7100 employed a custom manufactured dual laser module and free space coupling to the source and detector photomixers and was capable of continuously tuning from 100 GHz to 1800 GHz with a dynamic range of over 75 dB-Hz. The PB7100 was a rack mounted system that employed an external lock-in amplifier and a two foot by two foot optical breadboard for the optics. Some of these systems are still in use even though they are ten years old.

In 2008 Emcore released the PB7200. Unlike the PB7100, the PB7200 was designed from the beginning to be a light, portable, battery operated system that employed fiber-coupled source and detector photomixers. The PB7200 has gone through several years of development and revision and is now in its fourth generation. It is available as the basic single channel system which may be configured for either transmission or reflection measurements or as a two channel system that measures both transmission and reflection simultaneously. There is also an option to upgrade the basic system to have integrated phase control. It is also available as a rack unit which is suitable for OEM applications.

Bakman Technologies will continue to manufacture both the terahertz systems and the terahertz components. We will be working with the same distributors as previously to deliver these systems and components worldwide and are extremely excited about the future for this now fully developed product.
