The device (25) for obtaining an image of an object (7) situated obliquely with respect to the image plane, uses a prism (8) illuminated by a light source (1). The device is particularly used for searching, examining and identifying finger-prints. The device comprises between the reflecting prism (3) and the end portion (23) of the device (25) close to the image two deviating prisms (8) and (13) for evening the image field of the object (7), as well as a known optical system (17) to compensate for the astigmatism.
