A lens is formed from at least two sections or bodies that are shaped to mate with each other, and a multilayer optical film is sandwiched between these two sections. Smooth surfaces of each section combine to provide a first optical surface of the lens, e.g., a concave, convex, or flat optical surface. The multilayer optical film includes a stack of polymer layers configured to selectively reflect light by constructive or destructive interference, at least some of the polymer layers being birefringent. The multilayer optical film may thus be or comprise e.g. a reflective polarizer and/or a narrow band or otherwise notched reflector. The multilayer optical film has an extended terminus that separates the smooth surfaces of the two sections. Any edge defects such as cracks or delaminations that may exist along the extended terminus are characterized by an average defect distance of no more than 100 or 50 microns.

A method of forming a lighting system comprises providing a cavity having at least a first array of first optical elements and a second array of second optical elements that have a different shape than the first array, filling the cavity with a curable resin, applying a secondary optical element to the curable resin in alignment with the first optical array, curing the resin to form a cured assembly, and removing the cured assembly from the cavity.

A method and system for presenting targeted advertising during an Internet-based connection, such as a web-based data backup session in which data is communicated from a user computer to a remote storage area for archival via the Internet. According to the invention, the user computer is communicatively coupled to the server via a computer network and an asset profile for the computer is generated. The asset profile identifies the software applications that are currently loaded on the computer and the current hardware configuration for the computer including a processor type and connected hardware devices. In addition, the asset profile contains usage information such as a frequency of use for the various software applications. As a function of the uploaded asset profile, advertisements are selected from an advertisement database and are communicated to the computer for display to the user. Because of the detailed asset information, targeted advertising information having a high correlation to the user's computing behavior can be selected and displayed.
