CROSS REFERENCE TO RELATED APPLICATIONS This application relates to and claims priority to corresponding German Patent Application No. 101 15 915.3 filed on Mar. 30, 2001.
SUMMARY OF THE INVENTION The object of the present invention is to provide an apparatus of the type mentioned in the introduction which allows, with very high accuracy, adjustments of individual elements in relation to one another and very precise adjustments for setting purposes.
The configuration according to the invention of the adjustment device achieves very precise setting and adjustment. The transverse part provides height and length adaptation by way of which�in dependence on the opening angles of the trapezium or parallelogram�correspondingly transmitted changes in height and length occur.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows, partially in section, a side view of a configuration according to the invention;
FIG. 2 shows a section along line II�II from FIG. 1;
DETAILED DESCRIPTION FIGS. 1 and 2 illustrate a first embodiment of the apparatus according to the invention in principle. An adjustment apparatus 1 is arranged between a base plate 2, as base part, and a structure 3, as head part. The base plate 2 may consist, for example, of ceramic material or a similar material and serve as a rest for a mount 4 of an optical element 5, e.g. mirror or lens.
A transverse part 12 with a length-adjustment device extends between the mutually opposite side parts 10 and 11. The transmission of the change in length in the adjustment direction depends on the oblique-positioning angle of the side parts 10 and 11. An angle of 30� to the adjustment axis is illustrated. An angle of 45� gives a transmission of 1:1. The smaller the angle, the smaller is the transmission ratio. The side parts 10 and 11 are each in one piece and thus form solid-state articulations for adjustment purposes.
FIG. 3 shows an �interlinking� between the rough-adjustment device 8 and the precision-adjustment device 9. As can be seen here, the precision-adjustment device 9 is integrated in the rough-adjustment device 8. For this purpose, the rough-adjustment device 8, in turn, is provided with the transverse part 12, it being possible, in turn, for a temperature-compensation means to be provided in the transverse part 12. In this configuration, however, the transverse part 12 is divided in two over a large extent by a transverse slot 22. This likewise produces two arms which are located parallel to one another in the neutral position, corresponding to the arms 20 and 21 from FIG. 1, and precision adjustment takes place by the arms being correspondingly curved apart via actuation of the adjustment screw 18.
FIGS. 5 and 6 show three adjustment apparatuses �interlinked� with one another, to be precise in configurations as have been discussed in FIGS. 1 to 4. This configuration makes it possible to carry out (precision) adjustments in the axial direction and in the lateral direction or�expressed in quite general terms�in two planes which are located perpendicularly to one another. FIG. 5 shows more or less the configuration according to the exemplary embodiment from FIG. 3. In addition, two further adjustment apparatuses 1′ and 1″ are fastened or., e.g. screwed to, the reinforcing plates 24 and 25. FIG. 6 here shows the view of FIG. 5 from arrow direction VI. The two adjustment apparatuses 1′ and 1″ here are connected to the reinforcing places 24 and 25 in each case via their structure 3. It is also the case that these two adjustment apparatuses 1′ and 1′ are of the same construction as the adjustment apparatus according to FIG. 3, the only difference being that only one reinforcing or fastening plate 24 is provided. This means they each have a rough-adjustment device 8 and a precision-adjustment device 9.
Arrangement may take place in the top region, in the bottom region and also centrally�in relation to the axial length of the tube 30. This combined adjustment apparatus may be provided, for example, for a mirror 33, the adjustment apparatuses 1 acting on the circumferential wall of the mirror 33, while the coaxially arranged adjustment device according to FIG. 7 acts in the axial direction of the mirror 33.
For a precision-adjustment device 9, the walls of the expansion sleeve 39 run parallel to and/or coaxially with the basic mandrel 38. If a rough-adjustment device 9 is desired, a corresponding parallelogram form�as is illustrated by dashed lines�is preselected and then the walls of the parallelogram expand even further.
As can be seen, it is possible to provide for this purpose, for example, a top ring 48 and a bottom ring 49, which together constitute an intermediate lens ring. The ring 49 encloses the top ring 48, with a small spacing between them, by way of a sleeve-like widening 50. The end of the sleeve-like widening 50 may be connected to the top ring 48, For example, by soldering or welding. At the ends, the two rings 48 and 49 are located one above the other with a small spacing between them, an interspace 51 being formed in the process. The interspace 51 is provided, via 2 central bore 52, with a feed line 53 which is connected, in a manner which is not illustrated specifically, to a hydraulic device 54 (illustrated by dashes). In order to change the spacing A, and thus to change the height of the intermediate lens ring, via the hydraulic device 54 (not illustrated in any more detail), fluid is introduced under pressure via the bore 52 into the interspace 51 and the annular chamber 55 between the sleeve-like widening 50 and the circumferential walls of the rings 48 and 49. This produces�as seen in cross section�an H-shaped pressure chamber. If the sleeve-like widening 50 is correspondingly thin-walled and, if appropriate, also provided with an annular groove or recesses 56 in the circumferential wall, then the sleeve-like widening 50 curves outwards, when subjected to corresponding pressure, and thus results in a reduction in the spacing A.
