Abstract: The invention relates to optical cuvettes of the throughflow type and to the production thereof. The cuvette comprises a stratified block composed of at least three layers which together define a space constituting a doubly-bent continuous passage with a central elongated cavity communicating with two transverse branch-channels extending to the cuvette surface. An intermediate layer consists of a pair of transparent plates having oppositely arranged inner edges which are shaped in accordance with the path of said passage and are rounded off between the central cavity and the transverse channels, to provide streamline flow in the passage. Two lateral layers consist of plates which respectively close off the passage on either side thereof, between the shaped inner edges of said pair. The invention further provides a manufacturing method wherein two plate-edges are shaped in accordance with the profile of the doubly-bent passage and are oppositely arranged at a given distance to form an intermediate layer on to which two lateral plates are then mounted to close off the passage on either side thereof.

Abstract: The present invention relates to optical instruments, such as photometers including spectrophotometers, and relates more particularly to a light-shifting device of light refracting type for receiving a beam of light used in such instruments and shifting it into one or the other of two parallel paths. An optical instrument having a light source, means comprising a diaphragm for directing a collimated beam of light from the light source in a path along an optical axis, light-refracting means disposed in the path for receiving the light beam and shifting the beam from its incident path thereto alternately to each of two offset parallel paths which are parallel to the incident path, and means for supporting, in the offset parallel paths, sample and comparison objects to be scanned by the shifted light beam in those paths.
