Lenses for Mobile Phones with Camera Functions

High-Performance Lenses that Make Camera-Phones Capable of High Image Quality
Fuji Photo Optical has pioneered the development and supply of lens units that are key devices for camera-phones with 1 million or more pixels. While the lens units are extremely small, they offer high levels of image resolution even in image peripheries and feature reduced levels of the optical aberration that can cause color blurring. Moreover, the units are highly durable and reliable, being less sensitive to such factors as temperature changes. Incorporating three lenses - one molded glass aspherical lens and two plastic aspherical lenses - the lens units were engineered using leading-edge lens processing and assembly technologies. As the top manufacturer of pickup lenses for CD and DVD drives, Fuji Photo Optical has accumulated considerable expertise regarding plastic lenses, and it has the world's largest production capacity for these plastic lenses, surpassing 40 million lenses per month. In the future, Fuji Photo Optical intends to use its special strengths to earn more than 50% of the camera-phone lens market, which is projected to grow considerably.

Graded-Index Plastic Optical Fiber

Ideal for Home Networking Use in the Broadband Age
In view of the rapid increase in the volume and speed of data transmission on today's networks, Fujifilm has used the technologies that it has accumulated over many years in the fields of optical-designing and organic-compound designing techniques to develop Graded-Index Plastic Optical Fiber (GI-POF), which is capable of high-speed data transmissions of more than 1 gigabit per second. Moreover, the new GI-POF has a large diameter and is highly resistant to heat and humidity, easily workable and low-cost. In the emerging broadband era, the new GI-POF is expected to find extensive applications in home networking and diverse industrial-use signal transmission systems. In the future, the Fujifilm Group expects that it will be able to use its GI-POF in combination with the vertical cavity surface emitting laser (VCSEL) described below and other Group optical material products to take up the challenging task of creating high-speed optical data transmission systems.

Vertical Cavity Surface Emitting Laser

Compatible with 10 Gigabit Ethernet
Drawing on its exclusive semiconductor laser technologies Fuji Xerox has developed a VCSEL compatible with the new 10 Gigabit Ethernet (10GbE) standard for high-speed optical communications. This new laser and the 2.5-gigabit-per-second VCSELs marketed by Fuji Xerox since December 2001 are expected to be key devices in the broadband era. It is also expected that they will facilitate the acceleration of office and home communications infrastructure capabilities throughout the world.

Blue-Violet Laser Write-Once, Read-Many Optical Discs

New Organic Dye Coating Technology Ideally Suited to Mass Production
Fujifilm has developed next-generation, blue-violet laser write-once, read-many (WORM) optical discs that are produced using the Company's exclusive, high-productivity, ultrahigh-precision spin coating technology to apply an in-house developed organic dye to an optimised substrate. The new single-sided, 12cm-diameter discs offer storage capacities of up to 23.3 gigabytes, approximately five times the capacity of current DVDs. This capacity will allow for the recording of up to two hours of the high-definition digital television broadcasting that is expected to gain widespread acceptance in the near future.
