Bookham Unveils Expanded Display Technology Portfolio at SID 2005

New Technology Made Possible by Proprietary Deposition Technology and the World's Only Automated Color Wheel Assembly Facility

SAN JOSE, CA -- (MARKET WIRE) -- May 19, 2005 -- Bookham, Inc. (NASDAQ: BKHM), a leading provider of optical components, modules and subsystems, is expanding its offering to the growing display technology market with a new portfolio of products to be launched later this month at the SID (Society for Information Display) International Symposium in Boston.

The new family of ColorLoc™ light control thin film optical elements, made possible by Bookham's unique automated coating and assembly facility, offer theatre-quality optics for DLP (digital light processing), LCOS (liquid crystal on silicon), HTPS (high temperature polysilicon) liquid crystal display and LED (light emitting diode) projection systems. These products will be on display on the Bookham stand (number 2207).

"When it comes to light management, from projection imaging systems to fiber optics, Bookham thin films enable system designers and manufacturers to address their customers' needs," said Bruce Kuhlmann, Global Director of Sales - Display Products at Bookham. "The Bookham thin film product portfolio offers display designers the tools to optimize color, heat, noise, and UV/IR radiation in next-generation systems."

The expanded Bookham portfolio includes color filter wheels, which offer optimized color management and enhanced brightness in high-performance DLP imaging applications; light pipes for low loss light homogenization; UV/IR blockers, which prevent harmful ultraviolet and infrared radiation from degrading a projection system's performance; anti-reflection coatings (ARs); front surface mirrors (FSMs) for micro-display engine beam-folding; dichroics for color separation and combining, and custom filters and assemblies for LED illumination.

The new products benefit from the Bookham patented AED (Advanced Energetic Deposition) automated thin film optical coating technology, which enables unmatched stability and lifetime and environmental durability. This technology produces precision optical filters with negligible defects as well as higher throughput, tighter wavelength control, and lower cost than competing technologies. Because of its advantages, AED has enabled Bookham to take the leading worldwide market share position in telecommunications wavelength division multiplexing (WDM) filters.

The new family of Bookham ColorLoc™ light control thin film optical elements has already been shipped to a number of Tier 1 customers and will be fully available by the end of 2005.
