The purpose of the present invention is to provide a unit for establishing a measurement environment for correction purposes, which can provide a known optical environment to a probe tip during a measurement for correction purposes, whereby it becomes possible to provide the optical environment steadily without making the handling of the unit complicated.A probe (10) is equipped with a tip part (11) which comprises a light-receiving optical system involving an optical fiber or an imaging element and is provided at one end of the probe and a connector part (12) which is to be connected to a base unit (20) equipped with a detector and is provided at the other end of the probe, wherein a unit (40) for establishing a measurement-environment for correction purposes is provided in the connector part. The unit for establishing a measurement-environment for correction purposes constitutes an optical-environment-retaining chamber (42) having an opening (41) to which the tip part is to be inserted, and a known optical environment is applied to the tip part by inserting the tip part to the optical-environment-retaining chamber through the opening. A packaged article for diagnosis purposes comprises a tray, a probe accommodated in the tray, an adjusting jig equipped with a correction target, and a packaging bag in which the aforementioned components are accommodated.La présente invention concerne une unité pour établir un environnement de mesure pour des applications de correction, qui peut produire un environnement optique connu à une extrémité de sonde pendant une mesure pour des applications de correction, de telle manière quil devienne possible de produire lenvironnement optique régulièrement sans rendre la manipulation de lunité compliquée.Une sonde (10) est équipée dune partie de pointe (11) qui comprend un système optique de réception de lumière mettant en œuvre une fibre optique ou un élément dimagerie et est disposée à une extrémité de la sonde et dune partie de connec
