Abstract: Optical lenses are described and include a polymeric interference filter disposed on a curved polymeric substrate. The optical lens has an average light transmission of less than 2% across a band of blue light from 400 nm to at least 420 and up to 440 nm and substantially transmits blue light greater than 450 nm.

Abstract: An optical film or other optical body has a structured surface comprising Fresnel prisms. The Fresnel prisms define a complex topography. For example, a first and second Fresnel prism may have elongated first and second plan view shapes that form a “wye” (Y-shaped) feature. Alternatively or in addition, the Fresnel prisms may be arranged such that slopes of the Fresnel prisms define one or more saddle points. Furthermore, one or more of the Fresnel prisms may have prism shapes in plan view that include undulating portions, and the Fresnel prisms may be arranged in a slope sequence that defines one or more inflection points. The Fresnel prisms may be refractive or reflective, and they may provide the structured surface with a 3-dimensional appearance.

Abstract: A backlight that includes a front reflector and a back reflector that form a hollow light recycling cavity including an output surface is disclosed. The backlight further includes one or more light sources disposed to emit light into the light recycling cavity. The front reflector includes an on-axis average reflectivity of at least 90% for visible light polarized in a first plane, and an on-axis average reflectivity of at least 25% but less than 90% for visible light polarized in a second plane perpendicular to the first plane.

Abstract: A broadband partial reflector includes a multilayer polymeric optical film having a total number of optical repeating units that monotonically increases in thickness value from a first side to a second side of the multilayer polymeric optical film. A baseline optical repeating unit thickness profile is defined by a first plurality of optical repeating units and having a first average slope, and a first apodized thickness profile of the multilayer polymeric optical film is defined by a second plurality of optical repeating units having a second average slope being at least 5 times greater than the first average slope. The second plurality of optical repeating units define the first side of the multilayer polymeric optical film and join the first plurality of optical repeating units. The second plurality of optical repeating units are in a range from 3-15% of the total number of optical repeating units.

Abstract: A broadband mirror, polarizer, or other reflector includes separate stacks of microlayers. Microlayers in each stack are arranged into optical repeat units, and the stacks are arranged in series. At a design angle of incidence such as normal incidence, the second stack provides a second 1st order reflection band and a distinct second 2nd order reflection band with a second spectral pass band therebetween. The first stack provides a first 1st order reflection band that fills the second spectral pass band such that a single wide reflection band is formed that includes the first 1st order reflection band, the second 1st order reflection band, and the second 2nd order reflection band. In some cases, the single wide reflection band can include a first 2nd order reflection band of the first stack. In some cases, the first and second stacks may have apodized portions which monotonically deviate from respective baseline portions.
