FERRULE FOR AN EVANESCENCE FIELD SENSOR LINE

A ferrule (1, 1', 100) for an evanescence field sensor line (2') is specified that has a lower part (1A) and a correspondingly attachable upper part (1B), which respectively have a recess (10) substantially in the shape of a half shell in such a way that in the assembled state a guide tube (8) is formed for holding an optical wavelength (2) in a fashion enclosing the end face, in which a number of geometric structures (7) for locally fixing the optical wavelength (2) are respectively arranged in the recesses (10). Furthermore, a pressure sensor having such a ferrule (1, 1', 100) is specified that comprises an optical wavelength (2) designed for pressure acquisition by means of influencing the assigned evanescence field, and at least one optoelectronic module (13) that is assigned to the optoelectronic module (13).
