    • The invention relates to a device for producing parallel light beams by means of a beam splitter which divides a light beam into two parallel beams. Said beam splitter is a plane-parallel light-transmitting plate (1) that has a front (2) on which the light beam (5) is incident and is split up in such a manner that it leaves the plate (1) on the back (3) as two parallel beams (9, 11). The front (2) of the plate (1) is fully metal-coated in the area (6) that lies outside the incidence of the beam, and the back (3) is partially metal-coated in the area (7) of emersion of the transmitted beam (9). The plate (1) is tilted by a tilt axis (P) to change the angle of incidence ( gamma ) of the beam and the tilt axis (P) extends in the plane of extension of the plate (1) parallel to the plane-parallel lateral faces (2, 3) of the plate (1) and intersects the point of incidence (A) of the incident light beam (5).

    • The invention relates to a portable device for carrying out examinations on turbid media by means of a three-dimensional cross-correlation technique and for suppressing the influence of multiple scattering as well as to an adjusting method for adjusting said device. The inventive device is provided with a base plate (1) on which a laser (2) is disposed which can be adjusted by means of tilting devices or by means of mirrors for directing the laser beam vertically onto the wall of a cuvette (6) filled with a medium to be examined. The device is further provided with a translucent coated plate (7) that is in some sections completely metallized and in other sections partially metallized and that serves as a beam splitter (4). Said plate is firmly linked with the base plate (1) by means of a positioning fixture (8), the support surface (16) of which is disposed at a fixed angle with respect to the base plate (1). The positioning fixture (8) is detachably secured to the base plate (1) and to a cuvette fixture with receptacles for the cuvette (6) and for a cylindrical translucent container (70) filled with a liquid that is arranged on the base plate (1). Displacement devices for the cuvette fixture (5) allow a continuous positioning of the same on the base plate. Tilting and displacement devices for at least two mirrors and at least two detection optics are arranged on a base plate on the detection side of the device so that they can be fixedly positioned and so that the base plate can be firmly locked on the base plate (1). The device further comprises a photon multiplier and correlators for receiving cross- or auto-correlation functions.
