  • the light emerging from the lamp arrangement can also be guided through optical filters or, for example, a filter wheel in order to carry out a wavelength selection. This is of interest, for example, for fluorescence microscopy applications.
  • FIGS. 10 and 11 A concrete embodiment of a lamp arrangement according to the invention is shown in FIGS. 10 and 11.
  • the lamp arrangement has an outer housing shell 14 and an inner housing shell 12, wherein the inner housing shell is suspended by four integral with the inner housing shell 12 holding leg 84 on the outer housing shell 14 by means of the outer housing shell 14 with the retaining legs 84 connecting screws.
  • the two housing shells each have a socket 110 or 112 for at least one optical element, for example condenser lens, which define an optical axis C.
  • the suspension by means of the retaining legs 84 and the connecting screws is just in the plane containing the optical axis C, as explained with reference to FIG. 8.
  • a cooling by cooling fluid flows through the interior 16, which contains the lamp, not shown, in particular arc lamp, and through the gap 22.
  • an opening 114 of the outer housing shell 14 serving as an actuator pivoting body 46 is used, which corresponds to the carriage 46 of the examples of FIGS. 4 to 7.
  • the pivoting body 46 corresponds in particular to the carriage 46 according to FIG. 7, since it has a spherical-segment annular surface 84 which engages with an annular edge 82 on a circular cylinder shoulder 80 of the outer housing shell 14.
  • the engagement between the annular cylinder extension 80 and the pivoting body 46 can be maintained, for example, by these mutually biasing spring elements, as indicated by dashed lines in Fig. 10.
  • 120 denotes a mounting flange of the pivoting body 46 serving therefor, and 122 denotes an engagement-maintaining spring assembly.
  • a pivoting of the pivoting body 46 about a pivot point which is given by the center or radius of the spherical segment ring surface 84, is possible in two degrees of angular freedom and, for example, by means of two orthogonal acting on the pivot body 46 actuators, such as adjusting screws done.
  • a corresponding Adjusting screw is indicated by dashed lines in Fig. 10 and designated 124.
  • swivel body 46 designed as a slide member mirror holder 50 is used, which is adjustable by means of a screw in the Z direction relative to the swivel body 46.
  • This Z-direction corresponds exactly or approximately to the direction of the optical axis C.
  • an operating housing 128 on the outside of the outer housing shell 14 (see FIG. 11d), which overturns the pivoting body 46 and has two adjusting screws 130 and 132 which are connected via a deflection ball 134 or 136 act on the pivoting body 46 in mutually orthogonal directions and thus grant the Verschwenkept in the two degrees of angular freedom of the pivoting body 46 and thus held by the mirror holder 50 retroreflector.
  • the adjusting screws 126, 130 and 132 can also be connected by means of a flexible actuating member to a respective control knob accessible from the outside or the like.
