Devices for ex vivo microscopic analysis of samples and in vivo microscopic analysis of the skin

A device which is configured to operate in a first operating mode comprising an in vivo microscopic analysis of a skin and in a second operating mode comprising ex vivo microscopic analysis of a sample, the device comprising:

• a microscope lens comprising an optical axis;
• a mounting comprising a distal portion, in which the microscope lens is arranged, and a proximal portion which is fixedly joined to the distal portion, the distal portion comprising at one end a first transmission window;
• a first end piece which comprises at one end a second transmission window and which is configured to be fixed in a removable manner, in the first operating mode, to the distal portion of the mounting;
• a second end piece which is configured to be fixed in a removable manner, in the second operating mode, to the distal portion of the mounting;
• a sample carrier comprising a receiving surface which is configured to receive a sample in the second operating mode;
• a support which is configured to cooperate 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.
