    摘要： The present invention relates to an optical article and an optical filter comprising the same. The optical filter comprises an optical article containing one or more near-infrared absorbing dyes and having two or more absorption peaks comprising a first absorption peak and a second absorption peak in a wavelength range of 380 nm to 1,200 nm whereby the optical filter has advantages in that transmissivity is high with respect to light having the wavelength of a visible light region and transmissivity is suppressed to 0.6% or less with respect to light having a wavelength in the range of 800 nm to 1,000 nm so that ghost image problems can be prevented, and a yield and productivity can be improved through the reduction of poor assembly caused by the bending of the optical filter in an image device assembling process.

    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.
