    摘要： The prism, which is used particularly for optical data communication by means of a modulated light beam, is furnished with a transmissive prism body (60) which has two triangular first side faces (69) on its outer side and a base surface (77) therebetween, and two second side faces rising up from the base surface and inclined toward one another as light incidence and light exit faces (74, 76). The two second side faces (74, 76) are inclined oppositely, relative to an axis (79) running parallel to the base surface (77) and penetrating the planes in which the first side faces (69) lie, and each run at an acute angle (78, 80) to the axis (79) such that reflection radiation is reflected to the side.

    摘要： The invention relates to a tracking device (10) for a light beam between a transmitter and a receiver with line of sight between them, which is provided with an optical tracking unit, which defines an optical axis (12), and an optical deflection element (16) arranged therein, which optical deflection element, for the purpose of altering the angle of elevation at which the light beam is incident or emerges, is tiltable about a tilting axis (28) running perpendicularly to the optical axis (12), and which optical deflection element, for the purpose of altering the azimuth angle at which the light beam is incident or emerges, is rotatable about a rotation axis (30) parallel to the optical axis (12). Furthermore, the tracking device has an optical deflection element (16) having a reflective component (18), which has a reflection surface (24), and a transmissive component (20). Furthermore, the optical deflection element (16) is operable for the purpose of changing the angle of elevation by tilting about the tilting axis (28) within a first tilting angle range in a first mode, in which the light beam is deflectable by passing through the transmissive component (20) of the optical deflection element (16), and within a second tilting angle range in a second mode, in which the light beam is deflectable by reflection at the reflective component (18) of the optical deflection element (16).
