Advanced Photonix, Inc.(R) Receives Orders for Terahertz Systems from Major Development Labs.

CAMARILLO, Calif. -- Advanced Photonix, Inc.(R) (AMEX: API) ("API") announced today that Picometrix LLC ("Picometrix"), a wholly-owned subsidiary of API, has received orders for its T-Ray(TM) 2000 terahertz (THz) system from four major defense and leading university application development labs around the world. The New Jersey Institute of Technology ("NJIT"), the University of Adelaide, a major U.S. defense contractor, and a major foreign national lab have each placed orders for the T-Ray(TM) 2000 terahertz systems, with the combined orders totaling slightly over $1,000,000 to be fulfilled over the next two quarters. The T-Ray(TM) 2000 is capable of both THz spectroscopy and imaging and is used for application development. It was introduced in 2001 as the world's first commercially available THz instrument. Picometrix also offers the QA1000 THz system for on-line process control applications.

NJIT is a major public university with a worldwide reputation in THz development applications, headed by Dr. John Federici. Picometrix has had an on-going technical partnership with the Physics Department at NJIT for the development of THz applications for defense and homeland security markets.

The University of Adelaide located in Adelaide, Australia is a leader in many research and development fields. The THz Group at the University has received a major grant to develop Australia's first THz user facility, and Picometrix is proud to be a strategic supplier of the equipment enabling them to conduct THz development for a variety of applications.

The foreign national lab focuses on applied R&D, ranging from equipment for medical and pharmaceutical diagnostics to non-destructive testing for detecting contraband and security-threats.

Richard (Rick) Kurtz, Chairman of the Board and CEO, said, "These orders build on our existing relationships with various application development laboratories around the world in investigating the possible applications of THz technology. By creating and leveraging these relationships we will help drive the transition of THz application development from the research lab using the T-Ray(TM) 2000 to on-line process control solutions using our QA1000 THz system."
