Entrance angle definition

Entrance angle means the angle between the illumination axis and the reference axis. The entrance angle consists of a vertical component (symbol 1) and a horizontal component (symbol 2). For any direction the vertical angle β1 is always given first.NOTE 1 These angles are usually not larger than 90° but, for completeness, the full range is defined as -90° < β1 < 90° and -180° < β2 < 180°. NOTE 2 The entrance angle is sometimes as well referred to as illumination angle.
