摘要： The present invention relates to an optical article, and an optical filter and an imaging device including the same. The optical article 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 cut-off region, the optical article has the advantage of allowing the fabrication of an excellent near-infrared cut-off 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.

摘要： The present invention relates to an optical article and an optical filter including the same. The optical filter: includes an optical article which has at least two absorption peaks, including a first and a second absorption peak, in the wavelength range of 380 nm to 1,200 nm by containing two or more kinds of near-infrared absorbing pigments, and thus shows a high average transmittance of 86% or greater for light having a wavelength in the visible wavelength range; can limit the maximum transmittance of light having a wavelength in the range of 800 nm to 1,100 nm below 0.5%, so as to prevent lens flare; and can reduce assembly defects due to flexure of an optical filter in the process of assembling the optical filter to an image capturing apparatus, thereby improving yield and productivity.
