摘要： A polarization beam splitter selectively decouples detection light onto a detector such that it has a polarization direction that differs from the emitted illumination light. This enables the detection of the light scattered back in the eye lens at a high level of accuracy, since stray light from reflections at optical components of the light path is suppressed. In the generating of photo disruptions or other incisions, the ray exposure of the retina may be reduced in that the incisions being furthest away from the laser are induced first such that laminar gas inclusions with an existence duration time of at least 5 seconds result. In this manner the laser radiation propagated in the direction of the retina in further incisions are scattered and partially reflected such that the influence impinging upon the retina is reduced.
摘要翻译：偏振分束器选择性地将检测光分离到检测器上，使得其具有不同于所发射的照明光的偏振方向。这样就可以高精度地检测在眼镜片中散射的光，因为抑制来自光路的光学部件的反射的杂散光。在产生光破坏或其他切口时，可以减少视网膜的射线暴露，因为最远离激光的切口首先被引入，从而导致存在持续时间至少5秒的层流气体夹杂物。以这种方式，在另外的切口中沿视网膜的方向传播的激光辐射被散射并部分反射，使得影响到视网膜的影响减小。

摘要： The present solution is directed to the orientation of an eye for diagnostic and/or therapeutic purposes, wherein the line of sight need not coincide with the optical axis of the examination apparatus or treatment apparatus. The invention includes a fixating light source for generating a positionable fixating mark, a device for coupling this fixating mark into a beam path of an ophthalmological apparatus whose imaging optics project the fixating mark on the eye to be examined and/or treated, and a control unit by which the image of the fixating mark can be displayed at different distances and angular positions with respect to the optical axis of the ophthalmological apparatus so that the eye to be examined and/or treated is oriented to this fixating mark by foveal focusing and occupies a defined position with respect to the optical axis of the ophthalmological apparatus.

摘要： The invention relates to a device for machining an object by laser radiation, in particular by using the photodisruption method. Said device comprises an observation device for imaging the object and a laser scanning device by which the laser radiation is passed over a predetermined sector of the object for scanning said sector. According to the invention, such a device includes the observation device with a first lens for imaging the object; the laser scanning device with a second lens, through which the laser radiation is guided, in which both lenses with regard to the dimension of the regions to be produced in the images and/or with regard to their focal intercept are different from each other. This invention alternately images the respective region of the object in a first operating mode by the first lens and in a second operating mode by the second lens. It is thus possible to use in both operating modes a lens adapted to the intended imaging purpose.

摘要： The invention relates to a laser scanning microscope with a scanner and a microscope objective, and to a control method for such a microscope. In order to obtain sharp imaging of the sample in a laser scanning microscope, the distance between the microscope objective and the sample is usually varied for adjusting the focus position. However, relative movements between the objective and the sample can be problematic. In view of the costly special objective, internal focusing of the objective is a disadvantageous solution. An improved laser scanning microscope should make it possible to sharply image a sample with standard objectives without relative movement between the microscope objective and sample. According to the invention, a tube lens is provided which is displaceable along the optical axis, and the focus position is adjustable relative to a front optical element of the microscope objective by adjusting the tube lens.

摘要： An apparatus for material processing by laser radiation, including a laser source which emits a processing beam, and a beam path for focusing and scanning, the beam path focusing the processing beam into a processing volume and shifting the position of the focus therein. A beam splitting device generates several foci in the processing volume and the beam splitting device splits the processing beam up into a primary beam and at least one secondary beam and leaves the cross section of the beam in a pupil plane of the beam path unchanged during said division and introduces an angle of separation between the primary and secondary beams, so that these beams expand in the beam path in directions which differ by the angle of separation.
