Abstract: An optical filter is configured to have a regular transmittance of 60% or higher for light having a wavelength of 950 nm. The optical filter is also configured to be contracted by being heated at a temperature of 85° C. or higher, or a size change of the optical filter occurs from room temperature to 300° C. as monotonous increase in a tensile mode of a thermomechanical analyzer (TMA).

Abstract: A notched filter includes a multilayer having alternating first and second polymer layers, the first polymer layers each including an isotropic polymer thin film having in-plane refractive indices n1x and n1y, and the second polymer layers each including an isotropic or anisotropic polymer thin film having in-plane refractive indices n2x and n2y, where a thickness of each successive first polymer layer decreases with increasing distance from a centerline of the multilayer, and a thickness of each successive second polymer layer increases with increasing distance from the centerline. Such a filter may be configured to reflect incident light having a desired polarization state within a predetermined and relatively narrow band.
