Title:
OPTICAL ARTICLE AND OPTICAL FILTER COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2017/146413
Kind Code:
A3
Abstract:
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 imaging device assembling process.
