Abstract
An optical image capturing system, along an optical axis from an object side to an image side, includes a lens and an optical filter. The lens has refractive power. The optical filter is adjacent to the lens. The lens and/or the optical filter include or includes at least one visible light absorbing ingredient, absorb or absorbs a visible light with a wavelength range from 400 nm to 700 nm, and allows a light with a wavelength range greater than 800 nm to pass correspondingly. In another embodiment, a plurality of lenses is provided. At least one of the lenses is a filter lens. The filter lens includes the at least one visible light absorbing ingredient, so that the optical image capturing system could absorb the visible light and has a high transmittance of the infrared, thereby improving a light receiving efficiency and a working quality.
