Abstract: The present application is directed to a device for inspecting a keratinous surface of a user, preferably a hair sample, comprising a housing in which an image sensor is arranged to receive measurement light emitted from a measuring area configured to accommodate the keratinous surface, through a measurement window in a front wall of the housing, over a corresponding imaging light path, the device being further equipped with an illumination ring arranged in the housing rear of the measurement window around the imaging light path, said illumination ring having two opposed partially peripheral illumination portions separated by two opposed complementary partially peripheral non-illuminating portions, the illuminating portions being further configured to illuminate the measuring area through the measurement window over a illumination light path, said illumination light path having an angle of incidence comprised between 30 to 60°, preferably about 45°.

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).
