PRESS RELEASE Fakespace Delivers New Visualization System Technology to University of California Davis Campus

The significant cost reduction of Beacon XG over specialized projectors
allows more users access to the technology. Compared to polarized systems,
Beacon technology provides greater fidelity and is more versatile since it
does not require the use of special projection screen material. Xenogen 's biophotonic imaging
technology is used to provide more accurate and previously unavailable data
intended to result in the ability to make more timely and cost-effective
decisions at every step in the drug development process.
