Abstract: The present description relates to a device that includes: a microscope lens with an optical axis; a mounting that includes a distal portion, in which the microscope lens is arranged; a first end piece fixed in a removable manner, in a first operating mode for in vivo microscopic analysis of the skin, to the distal portion of the mounting; a second end piece fixed in a removable manner, in a second operating mode for ex vivo microscopic analysis of a sample, to the distal portion of the mounting; a sample carrier with a receiving surface; a support that cooperates with the second end piece in the second operating mode so as to receive the mounting so that the optical axis of the microscope lens is substantially aligned in a predetermined direction with respect to the receiving surface.

Abstract: The present description relates to a system for microscopic analysis of a sample that includes a microscopic analysis path and a sighting path. The microscopic analysis path notably includes an illumination path that illuminates the sample through a microscope objective of given nominal numerical aperture in a given field of view and a detection path including the microscope objective, and that detects in the field of view and according to a detection pattern, a light beam emitted by the sample in response to the illumination of the sample. The sighting path includes the microscope objective, a device for full field illumination of the sample, a two-dimensional detector, one or more imaging elements forming, with the microscope objective, a full field imaging device that forms a surface reflection sighting image of the sample of a given effective field encompassing the field of view.

Abstract: A dynamic focusing system (DFS) for an optical device for observing an object. The dynamic focusing system (DFS) has an objective housing (OBH) including a circumferential housing part (CIH) and a light-transmitting window (LTW); a chamber (ICH) filled with an immersion medium having a refractive index substantially equal to the refractive index of the object to be observed; a movable immersed objective (MIO) configured to move along at least one direction so as to vary the focusing depth and being at least partially immersed in the immersion medium. The immersion medium is confined in the chamber (ICH) by a deformable sealing member (DSM) attached to the movable immersed objective (MIO) and to the objective housing (OBH). The deformable sealing member (DSM) is configured to ensure that the volume of the chamber (ICH) remains substantially constant upon displacement of the movable immersed objective (MIO) relative to the objective housing (OBH).
