|Orlando, Florida – July 19, 2007: The University of Central Florida has signed a licensing agreement with Holochip Corp. for a portfolio of technologies that will allow zoom lenses, such as those used in digital cameras and camera phones, to be manufactured at a dramatically smaller size without|
Shin-Tson Wu, provost-distinguished professor of optics, and his research team at UCF’s College of Optics and Photonics, have developed and patented technologies in the field of adaptive lenses, some of which closely replicate the working of the human
Holochip Corp., based in Albuquerque N.M. and San Francisco, supplies such specialized lenses to manufacturers of camera phones, digital still cameras, medical and military equipment and other products. Under the agreement with the UCF Research Foundation, Holochip gains exclusive worldwide rights to Wu’s adaptive lens patents, including five U.S. patents and numerous foreign applications.
Conventional zoom lenses rely on mechanically moving groups of glass or plastic lenses in order to adjust focus, magnification and field of view. Adaptive lenses, however, offer the ability to change focal lengths while eliminating the need to mechanically change the location of the lens.
Wu, who joined
in 2001 after 18 years at Hughes Research Laboratories,
is known for his advances in the fields of
liquid crystal displays (LCDs) and liquid-crystal (LC) optics.
Wu was one of the first researchers to recognize the need for adaptive lenses,
and he has directed research that resulted in two distinct approaches.
The first, LC lenses, is based on the ability of liquid-crystal materials
to alter their refractive index in the presence of an external electric field.
With the appropriate selection of LC materials, substrates and device architecture,
lenses can be created that adjust their focal length upon an applied voltage.
The second approach, fluidic lenses, was inspired by principles of the human eye. The lens comprises a transparent optical fluid that is encapsulated within a flexible lens membrane and substrate. Upon compression of the lens body, the shape of the flexible lens membrane is modified, which results in an adjustment of the focal length of the lens.
Since this approach provides a wide range of focal power with almost no optical loss, it can be implemented in compact camera modules, making it attractive for size-limited applications such as digital cameras and cell phones. Likewise, the LC lens offers the ability to control high-order aberrations that

The lens, developed by Shin-Tson Wu,
provost-distinguished professor of optics, and his research team at
UCF’s College of Optics and Photonics,
replicates the function of the human eye.
The lens pictured was built for demonstration purposes,
so the aperture was expanded to 15 millimeters.
The lenses that are made for miniaturized applications, such as for cell phones,
are one to two millimeters in diameter.

can lead to blurriness,
making it attractive in applications such as free-space optical communications,
adaptive optics, corrective eyewear and cameras.
"This technology represents years of effort from Professor Wu and his research group at UCF," said Joe Giampapa, UCF’s tech transfer director. "We are very pleased to take the science to the next level in the commercial development by partnering with Holochip. We believe that Professor Wu’s research, together with Holochip’s aggressive commercialization strategy and manufacturing capabilities, has the potential to create a major impact on camera phones and numerous other optical products and industries."
"With the explosive growth of mobile imaging, and camera phone sales approaching one billion units worldwide, there is a critical need for high-quality, inexpensive and environmentally responsible adaptive lens solutions," said Robert Batchko, CEO of Holochip Corp. "With this agreement and our relationship with Professor Wu and his team, Holochip has taken a significant step toward meeting this need."
About Holochip Corp.:
Holochip Corp., a manufacturer of adaptive lenses, recently announced its flagship product, an adaptive polymer singlet lens, at the Conference on Lasers and Electro-optics (CLEO-2007) in Baltimore, Md. The company is privately held and was founded in 2004 with financial backing from ITU Ventures, the New Mexico Angels and others.
