Abstract: This ultraviolet sterilization tube comprises: a channel tube which internally has a processing channel; and a window which is arranged in at least a part of the tube wall of the channel tube. The window comprises: a fluorescent layer which contains a phosphor that emits visible light when irradiated with ultraviolet light; and an ultraviolet light blocking layer which is arranged more distant from the processing channel than the fluorescent layer, and which blocks ultraviolet light, while transmitting visible light.

Abstract: The present invention relates to the provision of a ferrule that can be connected even when the space for the connection is small. A ferrule of the present invention is configured to hold a plurality of optical transmission members and to be connected to another ferrule. The ferrule includes a first surface facing the end of the optical transmission members when the optical transmission members are held; and a plurality of second surfaces disposed opposite to the first surface in the ferrule. In the ferrule, the optical transmission members extend in the Z direction, and the ferrule is configured to be moved in a direction orthogonal to the Z direction to be connected to the other ferrule.

Abstract: The purpose of the present invention is to provide an ultraviolet sterilization device that can increase the ultraviolet irradiance near the center of a treatment flow path even at a position far from a light emitting element. This ultraviolet sterilization device comprises: a flow path tube having a linear treatment flow path therein; a light emitting element for emitting ultraviolet rays; and a reflector having a reflection surface for reflecting ultraviolet rays emitted from the light emitting element and collecting and directing the ultraviolet rays to the flow path tube. The ultraviolet sterilization device irradiates a fluid flowing in the linear treatment flow path with ultraviolet rays and sterilizes the fluid.

Abstract: The first light flux control member comprises: a concave first entrance surface, facing the plurality of light-emitting elements; and a first exit surface, and an outer exit surface. The second light flux control member controls and causes the light exiting from the first light flux control member to become oriented in the direction along the first central axis. In addition, when f represents the focal distance of the first light flux control member, and d represents the distance between the first central axis and the optical axis in the light-emitting element farthest from the first central axis, the surface light source device satisfies −0.6
