Abstract:
The invention relates to a method of manufacturing a polarizing lens, including conducting curved surface processing to change a shape of a polarizing film into a shape of a curved surface, conducting heat treatment by heating polarizing film that has been processed into a curved surface to a heating temperature of equal to or higher than 105° C. but less than 150° C., assembling an upper mold, a lower mold, and a seal member to provide a casting mold having a cavity within which the polarizing film following heating treatment is positioned, upper and lower molds being positioned opposite each other to sandwich the polarizing film at a space therebetween, and seal member sealing space between the upper and lower molds, casting a curable composition into the cavity, curing curable composition to provide a polarizing lens within which a polarizing film is positioned, and separating polarizing lens thus provided from casting mold.
Abstract:
A body-mountable device may include a first polymer layer, a second polymer layer, and a structure that includes a sensor between the first and second polymer layers. Forming the body-mountable device may involve positioning the structure on the first polymer layer and then forming, in a molding piece, the second polymer layer over the structure positioned on the first polymer layer. The molding piece includes a surface that supports the second polymer layer as the second polymer layer is being formed and a protrusion that extends from the surface to the sensor through the second polymer layer as the second polymer layer is being formed. The body-mountable device that is removed from the molding piece has a channel to the sensor formed by the protrusion.
Abstract:
The pressure sensitive adhesive sheet has a thickness of D, a water-vapor permeability of X, and a moisture content of Y. XD2 is 2.7×10−6 g/24 h or more and Y/D is 47 m−1 or less. A base polymer of a pressure sensitive adhesive composition that forms the pressure sensitive adhesive sheet is substantially free from an organic acid monomer component as monomer units. The pressure sensitive adhesive sheet is suitably used for bonding a polarizing plate to a transparent member disposed on a viewing-side of an image display device.

Methods of making optical films and optical stacks are described. A method of making an optical stack includes providing a thermoform tool centered on a tool axis and having an external surface rotationally asymmetric about the tool axis; heating an optical film resulting in a softened optical film; conforming the softened optical film to the external surface while stretching the softened film along at least orthogonal first and second directions away from the tool axis resulting in a conformed optical film rotationally asymmetric about an optical axis of the conformed film where the optical axis coincident with the tool axis; cooling the conformed optical film resulting in a symmetric optical film rotationally symmetric about the optical axis; and molding an optical lens on the symmetric optical film resulting in the optical stack.

A magnifying device including an optical system is described. The optical system includes an exit pupil, a reflective polarizer proximate the exit pupil, a partial reflector disposed adjacent the reflective polarizer opposite the exit pupil, and a quarter wave retarder disposed between the reflective polarizer and the partial reflector. The reflective polarizer is curved about two orthogonal axes and the partial reflector is spaced apart from the reflective polarizer.

Optical systems including first and second optical stacks and adapted to provide an adjustable dioptric correction are described. The first optical stack includes a first optical lens and a partial reflector. The second optical stack is convex along orthogonal first and second axes and includes a second optical lens and a reflective polarizer. The reflective polarizer has at least one first location having a radial distance r1 from an optical axis of the second optical stack and a displacement s1 from a plane perpendicular to the optical axis at an apex of the reflective polarizer, where s1/r1 is at least 0.1. A quarter wave retarder is disposed between the second optical stack and the first optical stack.
