ABSTRACT:
A beam divider which is particularly intended for use in smoke measuring apparatus comprises a transparent beam dividing plate (11) which is obliquely arranged in the beam path and is partially silvered at its lower side (11'). Two protective plates (13, 14) which form a closed internal space (12) leave the upper side of the beam dividing plate (11) above and below the optically active region. At least the protective plate (13) which crosses the beam path is transparent and the arrangement is closed in a dust-tight manner at the end faces.
