Abstract: Provided is a sensor head that can increase the flexibility of installation. The sensor head is a sensor head of a sensor for measuring displacement of a measurement object. The sensor head includes: a diffractive lens generating chromatic aberration along an optical axis direction on an incident light, a case part housing at least the diffractive lens inside, and fixing parts and used for fixing to a fixing object. The case part includes a cylindrical part having a cylindrical outer shape, and the outer shapes of the fixing parts and are within the outer shape of the cylindrical part when viewed in a central axis direction of the cylindrical part.

Abstract: Provided is a sensor head that can be miniaturized without compromising the measurement accuracy. A case of the sensor head includes a first case part and a second case part respectively having a substantially cylindrical shape with an axis, i.e., optical axis, as a central axis and being opened at an end part, and a connection member having a substantially annular shape with the axis as a central axis. The first case part and the second case part are connected to each other by screwing female thread parts and respectively formed on the inner circumferential surfaces thereof to a male thread part of the connection member.
