The geometry of the auxiliary deflection device can be further optimized in dependence on the geometric ray tracing.

The beam course of this interfering light is shown dotted as S1'.

An additional reverse beam path is thus present here.

The ray path through optical element OE will be explained below.

A valve 14 is also arranged in the beam path.

Such etalons fundamentally require a largely parallel beam course.

However, a periodic path of the rays is not obtained in this case.

A characteristic ray trace through a diverging lens is shown in Fig. 5.

The jet path of the fuel spray 14 can, in particular, be individually set by the inclination of the deflection element 15 .

Although the beam path is asymmetric, a rectangular phase plate may also be situated here.

When using this method it is also possible to additionally insert the pin hole 20 into the beam path.

A beam path within the plug is marked by thin lines with directional arrows. The respective optical fibers are represented by thin tubes.

It can be seen from these examples that the influence of resonator cavity deformation on the beam path in the ring laser is of very much more importance in the vertical direction than in the horizontal direction.

Via aspheric mirror surfaces of the folding mirrors or reflecting means and a suitable selection of the beaming-in direction into the laser intensifier or amplifier, with the described embodiments, the beam course or path in the intensifier or amplifier also on the intensifier or amplifier tube can be matched or adapted with non-circular but rather for example elliptical or rectangular cross section.

The optic axis 10, denoted in FIG. 2 by a broken line, of the photoelectric detectors corresponds to the path of the beam between the transmitter and the associated receiver.

A disadvantage of all the resonators described above is that the course of the beam in the resonator volume depends very heavily on the precise adjustment of all components which enclose the resonator volume.

In this case, the fact that there is in any case a focused and thus convergent/divergent beam path during production by laser drilling may be utilized.

For fine tuning between the beam path of the positron beam and that of the electron beam, a further, simple deflection system should be provided directly before the entry of one of the beam paths into the magnetic prism, preferably on the side of the positron source.

FIG. 5 shows an xy-coordinate. system which is placed over the parabolic plasma chamber 28, whereby the stream path within the plasma chamber corresponds to the y-axis.

The optical components and the beam path of some light beams of a projection exposure apparatus having a nested collector as shown in FIG. 17 are shown in FIG. 20 .

In other embodiments (cf. FIG. 4) a shape other than a cubic shape is provided. This may be, for example, a regular or irregular minimal shape with respect to material volume that is adjusted to the ray trajectory inside the beam splitter such that there are essentially no parts through which no light passes.

Table systems and frame systems are known generally from the prior art for mirror adjustments. These table and frame systems which serve as supports for mirror surfaces are actuated mechanically by adjustment screws or piezo-electrically when the desired beam path of a light bundle is directed for the first time (or after repeated readjustments) to a target point by switching on the light sources being used.

This is shown in FIG. 1 by the beam trace (shown by the broken line) above the multiple diaphragm 7.

In a first step 41, the lens excitations corresponding to the operating conditions which are to be calibrated are first adjusted in discrete steps via the touch panel 7 in such a manner that the electron beam has the desired beam path within the electron column 1.
