    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.

    Abstract: A broadband mirror, polarizer, or other reflector includes at least one stack of microlayers. Microlayers in the stack are arranged into optical repeat units. At a design angle of incidence such as normal incidence, the stack provides a 1st order reflection band, a 2nd order reflection band, and optionally a 3rd order reflection band. The 2nd order reflection band overlaps, or substantially overlaps, the 1st and/or 3rd order reflection bands to form a single wide reflection band. The wide reflection band may include the 2nd and 1st but not a 3rd order reflection band, or the 2nd and 3rd but not the 1st order reflection band, or it may include the 1st, 2nd, and 3rd order reflection bands, as well as still higher order reflection bands. The wide reflection band may cover at least a portion of visible and infrared wavelengths.

    Abstract: A broadband partial reflector includes a first multilayer polymeric optical film having a total number of optical repeating units from a first side to a second side of the first multilayer polymeric optical film and a second multilayer polymeric optical film having a total number of optical repeating units from a first side to a second side of the second multilayer polymeric optical film and an intermediate layer on the second side of the multilayer polymeric optical film separates the first multilayer polymeric optical film from the second multilayer polymeric optical film. The first multilayer polymeric optical film has a first baseline optical repeating unit thickness profile and a first apodized optical repeating unit thickness profile monotonically deviating from the first baseline optical repeating unit thickness profile and defining the second side of the first multilayer polymeric optical film. The second multilayer polymeric optical film has a second baseline optical repeating unit thickness profile and a second apodized optical repeating unit thickness profile monotonically deviating from the second baseline optical repeating unit thickness profile and defining the first side of the second multilayer polymeric optical film.

    Abstract: A front and back reflector are arranged to form a hollow light recycling cavity having an output region, and one or more light sources (e.g. LEDs) are disposed to emit light into the cavity. In one aspect, the back reflector has a design characterized by a first and second parameter. The first design parameter is a ratio of the collective emitting area of the light sources Aemit to the area of the output region Aout, and Aemit/Aout is preferably from 0.0001 to 0.1. The second design parameter is SEP/H, where H is the depth of the recycling cavity, and SEP is an average plan view source separation associated with the light sources. Other aspects of the disclosed extended area light sources are also described.
