PROBLEM TO BE SOLVED: To provide a multilayer optical film which reflects specific wavelengths and transmits or absorbs other wavelengths, and methods of making and using the same.SOLUTION: A multilayer optical film comprises an optical stack. The optical stack comprise: a) first optical layers comprising a first fluoropolymeric material, and b) second optical layers comprising a second fluoropolymeric material, where at least a portion of the first optical layers and at least a portion of the second optical layers are in intimate contact. The optical stack reflects at least a portion of wavelengths greater than about 700 nm, and at least 30% of target wavelengths are reflected at a 90 degree angle of incidence. 【課題】特定の波長を反射させ、他の波長を透過又は吸収する多層光学フィルム、並びにその作成及び使用方法を提供する。【解決手段】光学スタックを含む多層光学フィルムであって、前記光学スタックが、ａ）第１のフッ素重合体材料を含む第１の光学層と、ｂ）第２のフッ素重合体材料を含む第２の光学層と、を含み、前記第１の光学層の少なくとも一部分及び前記第２の光学層の少なくとも一部分が密接しており、前記光学スタックが、約７００ｎｍを超える波長の少なくとも一部分を反射し、且つ対象の波長の少なくとも３０パーセントが、９０度の入射角で、反射される、多層光学フィルム。【選択図】図１Ａ
