Advanced Photonix, Inc. Announces T-Ray 4000 Terahertz System Orders from

ANN ARBOR, Mich., Jun 11, 2008 — Advanced Photonix, Inc.(R) (AMEX: API) announced today that it has received purchase orders totaling more than $800,000 for T-Ray 4000(TM) Terahertz systems from leading university and government research labs in North America, including Rice University and Sandia National Laboratory. Picometrix(R), LLC, an API company, has been the leader in Terahertz (THz) imaging and spectroscopy systems since 2000, when it introduced the world’s first commercially available Terahertz system, the T-Ray 2000(TM). The T-ray 4000(TM), introduced in 2007, is the Company’s 4th generation system and represents a significant leap forward in commercial capability over previously available systems. It is more than twice as powerful as its predecessor system, weighs 90% less, is approximately 20 times smaller, is rugged enough to ship through airport checked baggage, and is a third less costly. The T-ray 4000(TM) is a modular system that is suitable for the research application development market as well as the industrial quality and process control non-destructive testing markets. The T-Ray 4000(TM) is a compact, high-resolution, high-speed, modular THz spectroscopy and imaging system that weighs approximately 50 pounds, is the size of a briefcase, and is suitable for either transmission or reflection mode applications. The system’s modular design enables it to be easily adapted to end user and OEM requirements for on-line quality control and serves as a platform for the more demanding defense and homeland security applications. Richard Kurtz, Chairman and CEO of API, stated, “We believe the T-Ray 4000(TM) continues to be the most advanced system in Terahertz technology. It greatly increases the productivity of the research scientist, which will ultimately help us accelerate the development and adoption of our Terahertz products in commercial and industrial applications. These sales to the research market represent the front end of the technology adoption cycle, and the beginning of the product revenue ramp in the first half of fiscal 2009.” About Advanced Photonix, Inc.
