Title (EN) OPTICAL PRODUCT AND OPTICAL FILTER INCLUDING SAME
(FR) ARTICLE OPTIQUE ET FILTRE OPTIQUE LE COMPRENANT

Abstract:
(EN) The present invention relates to an optical product, and an optical filter and an imaging device including the same. The optical product comprises: a near-infrared absorption glass substrate including a divalent copper ion as a chromatic ingredient; and a pigment dispersion layer formed on one surface or both surfaces of the near-infrared absorption glass substrate and having a near-infrared absorption pigment and an ultraviolet absorption pigment dispersed across the resin matrix thereof. Provided with a first and a second transmission blocking band, the optical product has the advantage of allowing the fabrication of an excellent near-infrared blocking filter that can effectively block light in near-infrared and ultraviolet bands and does not permit a difference in color sense with the change of incident angles.
(FR) La présente invention concerne un article optique, un filtre optique et un dispositif d'imagerie les comprenant. Le produit optique comprend : un substrat en verre d'absorption du proche infrarouge comprenant un ion cuivre divalent en tant qu'ingrédient chromatique ; et une couche de dispersion de pigment formée sur une surface ou les deux surfaces du substrat de verre d'absorption de l'infrarouge proche et dans la matrice de résine duquel un pigment d'absorption de l'infrarouge proche et un pigment d'absorption des ultraviolets sont dispersés. Comme il est pourvu d'une première et d'une seconde bande de blocage de transmission, le produit optique a l'avantage de permettre la fabrication d'un excellent filtre de blocage de l'infrarouge proche qui peut bloquer efficacement la lumière dans les bandes dans l'infrarouge proche et des ultraviolets et ne permet pas une différence de sens chromatique avec le changement d'angles incidents.
(KO) 본 발명은 광학 물품, 이를 포함하는 광학 필터 및 촬상 장치에 관한 것으로서, 상기 광학 물품은 구리 2가 이온을 착색 성분으로 포함하는 근적외선 흡수 유리 기재; 및 상기 근적외선 흡수 유리 기재의 일면 또는 양면 상에 형성되며 수지 매트릭스 내에 근적외선 흡수용 색소 및 자외선 흡수용 색소가 분산되어 있는 색소 분산층을 포함하며, 제1 투과저지대 및 제2 투과저지대를 구비함으로써 근적외선 및 자외선 영역의 광을 효과적으로 차단할 수 있을 뿐만 아니라 입사각 변화에 따른 색감차이가 없는 우수한 근적외선 차단 필터를 제작할 수 있는 이점이 있다.
