Abstract

PURPOSE:To simplify the structure of lens terminal for optical transmission, facilitate the adjustment thereof, and present at low price, by using a spherical lens having one plane so cut as to contain the spherical core on the lens side, and attaching an optical block to the same cut plane. CONSTITUTION:A spherical lens 11 is fabricated by cutting one plane thereof so as to contain a spherical core 10 on the lens side. A glass block 12 is attached to this cut plane. The contact position A of an optical fiber 13 and the glass block 12 is selected nearly in the focal position of the spherical lens 11. This spherical lens 11 and a package maintain a contact of high precision at point B, and by adjusting the angle of spherical lens 11 with respect to a luminous flux reference plane 15 by means of an adjusting jig 16, the incident light due to the optical fiber 13 and the exit light from the spherical lens 11 may be adjusted to be parallel to each other. Thus, a lens terminal for optical transmission, simple in structure and featuring easy adjustment and low price, may be obtained.
