OPTICAL FILTER, IMAGING DEVICE, AND OPTICAL SENSOR

The present invention provides an optical filter comprising a first glass substrate and a second glass substrate having an average transmittance of 80% or more of light having a wavelength of 400-600 nm, and an absorption layer provided between the first glass substrate and the second glass substrate, wherein the absorption layer contains at least one near-infrared-absorbing dye (A) selected from a squarylium dye, a cyanine dye, and a diimonium dye, and a transparent resin having a glass transition temperature of 130 DEG C or above. 一种滤光片，所述滤光片具有：波长400nm～600nm的光的平均透射率为80％以上的第一玻璃基材和第二玻璃基材、以及设置在第一玻璃基材与第二玻璃基材之间的吸收层，其中，所述吸收层含有具有特定的光吸收特性的选自方酸内盐色素、花青色素和二亚铵色素中的至少一种近红外线吸收色素(A)和玻璃化转变温度为130℃以上的透明树脂。
