Abstract
An optical lens device assembly is provided which is capable of being substantially free from a deviation in an optical axis of an optical lens caused by errors of its manufacturing, thus preventing a drop in coupling efficiency and enabling easy alignment of the optical axis of the optical lens. One of end faces of two optical lens is used as a lens plane and the two optical lens are optically in series coupled. The two optical lenses are placed in a manner that their non-lens planes face each other.
