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.
Claims18
An optical lens device assembly comprising:
- two optical lens devices each having a truncated cone shape as a whole and being made up of an optical element one end face of which serves as a lens plane and another end face of which serves as a non-lens plane, and being placed on a reference plane so as to be optically coupled in series;
- and
- wherein said two optical lens devices are placed in a manner that said non-lens planes of said two optical lens devices face each other.
