摘要： Optical bodies are described. In particular, optical bodies having a birefringent multilayer optical film and a continuous adhesive layer with a thickness less than 20 micrometers are described. Optical bodies described herein exhibit reduced occurrence and severity of a non-uniformity defect known as “orange peel.”

摘要： A mirror system for a side- or rear-view mirror of a vehicle includes a light absorbing layer and an optical film having a plurality of layers disposed on the light absorbing layer. For substantially normally incident light and a blue, green, and red wavelength range extending from about 420-485 nm, 525-575 nm and 625-740 nm, respectively, and for at least one polarization state, the plurality of layers includes a reflection band having a substantially flat top region at least 100 nm wide. The reflection band includes left and right band edges at respective short and long wavelength sides. The plurality of layers has an average optical reflectance R1 of greater than about 70% and a standard of deviation of less than about 5% in the substantially flat top region. An average optical reflectance Rb is less than about 0.8R1 in the blue wavelength range.

摘要： An article including a reflector with a reflectance band that is substantially constant as a function of an incidence angle; a polymeric multilayer film packet including a front surface partial reflector with a reflectivity that increases with an increasing incidence angle away from the normal; and a wavelength-selective absorber with a transmission band that at least partially coincides with the reflectance band of the reflector.

摘要： A heads-up display for viewing by an eye of a passenger of a vehicle includes a windshield with a reflective polarizer disposed adjacent to a first outermost glass surface of the windshield, a display configured to emit an image toward the windshield, the windshield reflecting between 15% and 85% of the emitted image toward the passenger, and a phase retarding plate disposed in an optical path between the display and the windshield. The windshield is configured to receive the image emitted by the display after the image has been transmitted by the phase retarding plate and to reflect at least a portion of the received image as a reflected image toward the eye of the passenger. The phase retarding plate modifies a polarization state of the reflected image to improve a viewing characteristic of the reflective image depending on a viewing angle of the eye of the passenger.

摘要： A multilayer optical film includes a plurality of polymeric layers arranged sequentially adjacent to each other. A difference in thickness between spaced apart first and second polymeric layers in the plurality of polymeric layers is less than about 10%. Each polymeric layer that is disposed between the first and second polymeric layers has a thickness less than about 400 nm. Each layer in a group of at least three polymeric layers in the plurality of polymeric layers that are disposed between the first and second polymeric layers has a thickness greater than an average thickness of the first and second polymeric layers by about 20% to about 500%. The group of at least three polymeric layers includes at least one pair of immediately adjacent polymeric layers.

摘要： An optical stack for reflecting and transmitting light in a predetermined wavelength range includes stacked first and second optical films, the predetermined wavelength range defining a first wavelength range and a remaining wavelength range. For normally incident light and for each wavelength in a first wavelength range, the first optical film substantially reflects light having a first polarization state, and substantially transmits light having a second polarization state. For each of the first and second polarization states, for wavelengths in the first wavelength range, the second optical film has a maximum optical transmittance Tmax for light incident at a first incident angle, and an optical transmittance Tmax/2 for light incident at a second incident angle, where the second incident angle is greater than the first incident angle by less than about 50 degrees. For wavelengths in the remaining wavelength range, the second optical film reflects at least 80% of light.

摘要： Optical stacks are described. In particular, optical stacks including reflecting-absorbing polarizers and quarter-wave plates are disclosed. The optical core of the optical stack—which includes a reflecting-absorbing polarizer with at least one skin layer including polarizing dye—may be co-extruded or co-stretched.

摘要： A polarizer including an oriented polymeric first layer is described. The oriented polymeric first layer is preparable from a mixture of polyvinyl alcohol and crosslinker where the crosslinker is included in the mixture at 5 to 40 percent by weight based on the total weight of the polyvinyl alcohol and crosslinker. The oriented polymeric first layer is a substantially uniaxially drawn layer, in that for U=(1/MDDR−1)/(TDDR1/2−1), U is at least 0.85, with MDDR being a machine direction draw ratio and TDDR being a transverse direction draw ratio.
