Title (EN) OPTICAL FILTER, AMBIENT LIGHT SENSOR AND SENSOR MODULE
(FR) FILTRE OPTIQUE, CAPTEUR DE LUMIÈRE AMBIANTE ET MODULE DE CAPTEUR
(JA) 光学フィルター、環境光センサーおよびセンサーモジュール
Abstract:
(EN) One problem of the present invention is to provide an optical filter capable of realizing both an excellent visible light transmittance and an excellent near-infrared ray-shielding performance even if an incident angle becomes large. The optical filter of the present invention has a substrate (i) including a light absorbing layer, and transmits visible light, wherein the light absorbing layer has a absorption maximum within a wavelength range from 750 nm to 1,150 nm, and, in the wavelength within a range from 850 nm to 1,050 nm, an average OD value of 2.0 or more when measured from a direction perpendicular to the optical filter, and an average OD value of 2.0 or more when measured from an angle of 60° with respect to a direction perpendicular to the optical filter.
(FR) L'objectif de la présente invention est de fournir un filtre optique apte à réaliser à la fois une excellente transmittance de la lumière visible et une excellente performance de protection contre des rayons en infrarouge proche même si un angle d'incidence devient grand. Le filtre optique selon la présente invention comprend un substrat (i) comprenant une couche absorbant la lumière, et transmet la lumière visible, la couche d'absorption de lumière ayant un maximum d'absorption dans une plage de longueur d'onde comprise entre 750 nm et 1150 nm et, dans la longueur d'onde dans une plage de 850 nm à 1050 nm, une valeur OD moyenne de 2,0 ou plus, mesurée depuis une direction perpendiculaire au filtre optique, et une valeur OD moyenne de 2,0 ou plus, mesurée depuis un angle de 60° par rapport à une direction perpendiculaire au filtre optique.
(JA) 本発明の課題の一つは、入射角度が大きくなった場合でも優れた可視光透過率と近赤外線カット性能を両立可能な光学フィルターを提供することである。本発明の光学フィルターは、光吸収層を含む基材(i)を有し、かつ、可視光を透過する光学フィルターであって、前記光吸収層が波長750~1150nmの領域に吸収極大を有し、波長850~1050nmにおいて、前記光学フィルターの垂直方向から測定した場合の平均OD値が2.0以上であり、かつ、前記光学フィルターの垂直方向に対して60°の角度から測定した場合の平均OD値が2.0以上であることを特徴とする。
