    • The present application discloses filters and methods of making filters. In one aspect, a filter comprises a multilayer optical film (MOF) having a first reflection band, the MOF including distorted portions, the distorted portions having a second reflection band different from the first reflection band, a transparent outer layer disposed on a first side of the MOF, and an IR blocking material residing on the MOF and between the transparent outer layer and the MOF, wherein the IR blocking material is selectively disposed in the distorted portions. In another aspect, a method of producing a filter comprises the steps of providing a multilayer optical film (MOF) having a first reflection band, distorting portions of the MOF, the distorted portions having a second reflection band, different from the first reflection band, and transferring a layer of IR blocking material to the distorted portions of the MOF.
    • 本申请公开了制造过滤器的过滤器和方法。 一方面,一种滤光器包括具有第一反射带的多层光学膜(MOF),所述MOF包括失真部分,所述失真部分具有不同于所述第一反射带的第二反射带,设置在第一侧的透明外层 的MOF和IR阻挡材料,其位于MOF上,并且在透明外层和MOF之间,其中IR阻挡材料选择性地设置在变形部分中。 另一方面,制造滤波器的方法包括以下步骤:提供具有第一反射带的多层光学膜(MOF),MOF的变形部分,具有与第一反射带不同的第二反射带的失真部分, 并将一层IR阻挡材料转移到MOF的变形部分。
