Abstract: This device for inspecting a human body portion (12) comprises: a frame (14), defining an observation window (26); an optical sensor, configured to capture a measurement luminous radiation (C) from the human body portion (12), and an illumination arrangement, configured to illuminate the human body portion (12), the illumination arrangement comprising at least one light source (30), each light source (30) being configured to produce an emitted luminous radiation (A). The illumination arrangement comprises at least one concave mirror (32) configured to reflect the emitted luminous radiation (A) produced by at least one of the light sources (30) in a reflected luminous radiation (B), the reflected luminous radiation (B) being collimated toward the observation window (26) so as to illuminate the human body portion (12).
