T-Ray Science Grants Technology License to Toptica Photonics, Inc.

VANCOUVER, BRITISH COLUMBIA--(Marketwire - April 29, 2010) - T-Ray Science, Inc. (TSX VENTURE: THZ) (“T-Ray” or the “Company”) an emerging leader in the field of TeraHertz (“THz”) research, is pleased to announce that it has granted a Licensing Agreement to Toptica Photonics, Inc. (“Toptica”).

Toptica is a global market leader for THz sources and their applications, offering laser-based time and frequency domain sources. Part of the Toptica’s portfolio is offering customers a THz Standard Package plus Spectroscopy Kit product which uses a coherent detection technique for continuous wave (“cw”) THz signals. Under the terms of the Licensing Agreement, T-Ray will collect royalties on the sales of this product in the United States.

“The quality of Toptica’s products and their expertise in the field of THz imaging are world class,” said Thomas Braun, CEO of T-Ray. “This is a significant endorsement of T-Ray’s cw THz platform technology. While T-Ray continues to focus on developing its own skin cancer imaging device, we are forecasting additional Licensing Agreements to be concluded this year, positioning the Company for accelerated growth.”

T-Ray’s platform THz imaging technology has been shown to have numerous potential applications including homeland security, the detection of explosives and ceramic knives; process control in the paper, plastics, petro chemical and pharmaceutical industries; and medical imaging for detection of skin and other cancers. THz waves are also a safe, accurate, and economical alternative to other scanning methods such as high frequency ultrasound, magnetic resonance imaging, and near-infrared imaging. This emergent technology has the potential to revolutionize the way many diseases are diagnosed, and ultimately cured. Numerous studies have shown that THz imaging can be used to image various cancers which continues to be the focus of T-Ray’s skin cancer imaging research and development.
