    Abstract: The optical transmission factor of an object (A) is measured by mutual measuring technology using a pair of identical units (44, 50) located on opposite sides of the object. Each of the units (44, 50) comprises a pair of beam splitters (47, 48; 53, 54), a light source (45, 46; 51, 52) for illuminating the object through a first beam splitter (47) and providing an offset beam (56) from the first beam splitter (47), and a photo-detector (49, 55) for converting optical power from the other unit (50) and the offset beam (56). Each of the beam splitters (47, 48; 53, 54) is substantially in parallelogram shape with two pairs of confronting planes (24, 25; and 22, 23), a first pair of the planes (24, 25) being not perpendicular to the second pair of planes (22, 23). One of the first pair of planes (24) is mirror coated for reflecting the beam internally, such that split beams (29, 31) obtained from a single beam (27) share a common point (200) on the plane (23). Thus, dust and dirt free measurement using no mechanically moving means is accomplished.

    Abstract: Ein optisches Transmissionsgerät weist eine Lichtquelle, eine dahinter befindliche Frontlinsenanordnung, einen am anderen Ende der Messstrecke angeordneten Reflektor und Mittel zum mehrfachen Hin- und Herführen von Licht zwischen der Frontlinsenanordnung und dem Reflektor auf. Ausserdem ist eine Lichtempfangsanordnung vorgesehen. Um jedwedes Langzeitdriften durch Alterungseinflüsse u.dgl. automatisch auszuschalten, ist das von der Frontlinsenanordnung (12) ausgehende Licht in zumindest zwei Teilbündel (II. 2, 3, 4, 5, 6) unterteilt. Die Teilbündel durchlaufen die Messstrecke (11) zwischen der Frontlinsenanordnung (12) und dem Reflektor (13) unterschiedlich oft, bevor sie eine Lichtempfangsanordnung (14) erreichen. In einer elektronischen Auswerteschaltung (15) werden die störenden Einflüsse eliminiert.
