Abstract: This optical receptacle comprises: a first optical surface on which light emitted from a VCSEL is incident; a first reflection part which reflects, as monitor light traveling to a detection element; a light separation part which separates monitor light and signal light; a second optical surface which emits the signal light to the end surface of the optical transmission body; and a third optical surface which emits the monitor light reflected by the first reflection part and the monitor light separated by the light separation part to the detection element. Two second reflection parts of the light separation part are disposed so as to be located within a luminous flux of the light incident on the first optical surface such that a predetermined condition is satisfied.

Abstract: An electromagnetic flux controlling member includes an incidence surface for allowing incidence of an electromagnetic wave, and an emission surface for emitting the electromagnetic wave incident on the incidence surface to an outside. At least one of the incidence surface and the emission surface includes a base curved surface and a plurality of protrusions arranged on the base curved surface. Each of the plurality of protrusions includes a conical tip portion disposed such that at least a part of an edge of a bottom surface of the conical tip portion makes contact with the base curved surface, and a partially columnar leg portion disposed between the conical tip portion and the base curved surface. A central axis of the conical tip portion and a central axis of the partially columnar leg portion are parallel to a main axis of the electromagnetic flux controlling member.

Abstract: The purpose of the present invention is to provide a liquid handling method that makes it possible to simply isolate a droplet, a fluid handling device used in this method, and a fluid handling system. This fluid handling method serves to flow a fluid including a solvent and a droplet through a fluid handling device comprising an inlet, a first flow path having one end connected to the inlet, a chamber connected to the other end of the first flow path, a second flow path having one end connected to the chamber, and an outlet connected to the other end of the second flow path. This fluid handling method includes an introduction step for introducing the fluid through the inlet and accommodating the droplet in the chamber, a rotation step for rotating the fluid handling device after the introduction step, and a removal step for removing the droplet from the inside of the chamber after the rotation step. In the introduction step, the fluid handling device is disposed such that the chamber widens from the position where the chamber and the second flow path are connected in the direction opposite from the direction of gravity.
