摘要： An optical element to be interposed between an optical transmission line and a light-emitting element or a light-receiving element such that an optical path from one side to the other passes through the optical element is provided. At least one surface of the optical element is provided with a first light-collecting area and a second light-collecting area. A surface of the first light-collecting area is configured such that light from the one side is received by the other side. A surface of the second light-collecting area is an annular surface or a part of the annular surface and is configured such that light that has passed through the second light-collecting area forms an image in the shape of a ring or a part of the ring at a position between the optical element and the other side.

摘要： A position determination method for determining a position of a point on a flat surface by observing the position of the point and a position of a fiducial portion on the flat surface in an image of a measuring system provided with an imaging optical system using coaxial episcopic illumination is provided. The fiducial portion is in the shape of a pillar at least in the basal portion and provided with an inclined surface surrounding the foot of the pillar. The method includes the steps of determining a position of the outer boundary of the foot from the boundary between the inclined surface and the flat surface in the image; determining the position of the fiducial portion from the position of the outer boundary of the foot; and determining the position of the point with respect to the position of the fiducial portion.

摘要： The element according to the present invention has a first plane (201) and a second plane (203) forming a prescribed angle with the first plane. The second plane is provided with at least three portions for position determination (101A 101B, 101C, 101D) arranged on the second plane sufficiently spaced apart from each other, allowing the identification of the second plane. Each portion for position determination is formed in a convex shape with respect to the second plane. A tangential plane (TL) to the surface of each portion for position determination at a point on a border line between the second plane and the surface forms a single plane and tangential planes of the portions for position determination are parallel to one another.

摘要： An optical unit of plastic provided with a surface for incident light and a surface for outgoing light, wherein the surface for incident light is designed to face a light source and the surface for outgoing light is designed to face an element for receiving light so as to optically connect the light source and the element for receiving light and wherein the optical unit is so shaped that light that comes from the light source and is incident on the surface for incident light forms a first image of the light source within the optical unit and a second image of the light source after having gone through the surface for outgoing light and the optical unit is provided with an attenuating portion for attenuating the quantity of light passing therethrough in the vicinity of the position where the first image is formed.
