Title (EN) OPTICAL FILTER, AND IMAGING DEVICE COMPRISING SAME
(FR) FILTRE OPTIQUE ET DISPOSITIF D'IMAGERIE LE COMPRENANT
(KO) 광학 필터 및 이를 포함하는 촬상 장치
Abstract: front page image
(EN)The present invention provides an optical filter that comprises an optical absorption layer and a near-infrared reflection layer, the optical absorption layer having an absorption maximum in the wavelength range of 670-720nm, the wavelength at which the light transmittance of the near-infrared reflection layer is 50% being in the range of 690-720nm, and the filter satisfying mathematical formula (1). The present invention also provides an imaging device comprising the optical filter. [Mathematical formula (1)] ΔE*≤1.5. In mathematical formula (1) ΔE* represents the colour difference between light that has entered in the vertical direction of the optical filter and passed through the optical filter, and light that has entered in the direction at an angle of 30° to the vertical direction of the optical filter and passed through the optical filter.
(FR)La présente invention concerne un filtre optique qui comprend une couche d'absorption optique et une couche de réflexion proche infrarouge, la couche d'absorption optique comprenant un maximum d'absorption dans la plage de longueurs d'ondes de 670-720 nm, la longueur d'ondes à laquelle la transmittance de la lumière de la couche de réflexion proche infrarouge est de 50% se trouvant dans la plage de 690-720 nm, et le filtre satisfaisant la formule mathématique (1). La présente invention concerne également un dispositif d'imagerie comprenant le filtre optique. [Formule mathématique (1)] ΔE*≤1,5. Dans la formule mathématique (1), ΔE* représente la différence de couleur entre la lumière ayant pénétré dans la direction verticale du filtre optique et traversé le filtre optique, et la lumière ayant pénétré dans la direction selon un angle de 30° par rapport à la direction verticale du filtre optique et traversé le filtre optique.
(KO)본 발명은 광흡수층 및 근적외선 반사층을 포함하는 광학 필터로서, 상기 광흡수층은 670 내지 720 nm 파장 범위에서 흡수 극대를 가지며, 상기 근적외선 반사층의 광 투과도가 50%가 되는 파장은 690 내지 720 nm 범위에서 존재하며, 하기 수학식 1을 만족하는 것을 특징으로 하는 광학 필터 및 상기 광학 필터를 포함하는 촬상 장치를 제공한다. [수학식 1] ΔE* ≤ 1.5 상기 수학식 1에서, 상기 ΔE*는 상기 광학 필터의 수직 방향에서 입사되어 상기 광학 필터를 투과한 광과, 상기 광학 필터의 수직 방향과 30°를 이루는 각도로 입사되어 상기 광학 필터를 투과한 광의 색차를 의미한다.
