POLARIZED LENS CONTAINING MIXTURE OF NIR DYES FOR WIDE VARIETY OF NIR PROTECTION

To provide an optical element and a method for manufacturing the same.SOLUTION: An optical element contains two or more kinds of near infrared absorbents mixed in an optical base material and one or more functional films arranged on the optical base material. A method for manufacturing the optical element includes mixing two kinds of near infrared absorbers having different near infrared wavelength absorption ranges and residual colors with a precursor of the optical base material. The mixture is then processed to manufacture the optical element having a wide variety of near infrared wavelength absorption range, a high near infrared absorption level and/or a homogeneous color distribution.SELECTED DRAWING: Figure 1 【課題】光学素子及びその製造方法を提供する。【解決手段】光学素子は、光学基材中で混合される２種以上の近赤外線吸収剤と、光学基材上に配置された１つ又はそれ以上の機能性フィルムとを含有する。光学素子を製造する方法は、異なる近赤外線波長吸収範囲及び残留色を有する２種の近赤外線吸収剤を、光学基材の前駆体と混合することを含む。混合物をその後処理し、広範な近赤外線波長吸収範囲、高い近赤外線吸収レベル、及び／又は均質な色分布を有する光学素子が製造される。【選択図】図１
