ABSTRACT:
An optical cell provides a measuring chamber which is L-shaped with an absorbance optical path lying along the horizontal leg of the L. A second optical path is provided transverse to the absorbance path and sized to permit the passage of radiation into the entire L-shaped chamber. The exit slit for the cell receives radiation from the entire vertical leg of the L and may serve as the entrance slit to a photometer.
