A detector (14) is provided for receiving light from an examination region (24) of the skin surface ("s"). A light barrier (18) substantially impervious to the light emitted from the light source (12) intimately engages the skin surface ("s") to define a boundary between the illumination region (22) and the examination region (24). 5847826_11/3 26 -10 12 "b1" 22 "b2 "lb3l' lb l f / FIG. 1
