Abstract

The photosensor device comprises a photosensitive element (6) mounted on a base (7) with its sensitive surface facing upwards. The sensor is covered by a conical screen (8) forming an optical integrator. The optical transmission through the conical screen varies according to the angle at which light enters with respect to the vertical. A transmission mask (9) is applied to the outside surface of the cone, between two angles (theta-1, theta-2). This is intended to attenuate the sensitivity of the sensor when light is incident between two specified angles (aCmin, aCmax).
