Patent number: 9062850Abstract: A reflecting member made from a tube-shaped member has an inner peripheral surface that structures a reflecting surface on an axis of the tube-shaped member. A slope, relative to the axis, of a tangent line of the inner peripheral surface in a cross-sectional plane containing the axis changes monotonically along the axis. In relation to a target facing a smaller opening of the tube-shaped member, at a specific distance therefrom, and having a flat region perpendicular to the axis and axially symmetrical relative to the axis, of an electromagnetic radiation incident along the axis from a larger opening of the tube-shaped member, that radiation reflected at a specific location on the larger opening side is incident on one end side of the flat region, and that radiation reflected at a specific location on the smaller opening side is incident on the other end side of the flat region.Type: GrantFiled: March 13, 2013Date of Patent: June 23, 2015Assignee: Azbil CorporationInventor: Raita Mori
