  • Publication number: 20080123051
    Abstract: A solution by which an examination of the cornea for possible encapsulations, air bubbles, or other irregularities following a refractive surgery can be carried out directly at the treatment device instead of the patient having to be transferred to an examination device. The additional slit illumination system includes two slit projector units substantially symmetrically mounted at an angle of about 40° to the optical axis of the refractive treatment device, and fixed and focused on the eye of the patient to be examined. The slit projector units include a light source, a projection optical system, and beam forming and/or conducting optical components. Although intended for surgical microscopes, it can also be used for other opthalmologic treatment devices that would benefit from a slit projection system for the examination before, during, or after the treatment procedure.

  • Publication number: 20080058734
    Abstract: 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.

  • Publication number: 20070253083
    Abstract: An adapter for coupling a laser processing device to an object, said adapter having a central region which can be moved into the beam path of the laser processing device, an illumination beam path through which illumination radiation can be guided for illumination of an object field which can be covered by the central region, and a peripheral region located outside the central region and by which the adapter can be mounted on the object and/or on the laser processing device, wherein the illumination beam path extends in the peripheral region and guides illumination radiation, coupled into the peripheral region, to the object field direct and/or via the central region.

  • Publication number: 20070237620
    Abstract: What is described is an adapter for mechanically coupling a laser processing device to an object, said adapter comprising having a central region which can be moved into the beam path of the laser processing device, which beam path extends up to the object along an optical axis, and a peripheral region located outside the central region, said adapter being fixable to the laser processing device on the one hand and being provided so as to contact the object with its central region on the other hand, wherein fixing means are provided at the peripheral region, said means allowing the adapter to be releasably fixed to a receiving part of the laser processing device such that, upon application of a determined pulling force along the optical axis, the fixing means are removable from said receiving part.

  • Publication number: 20070010803
    Abstract: The invention relates to an adapter for coupling a laser treatment device to an object for treatment, whereby the adapter has an input side, which may be fixed relative to the laser treatment device, by a locking mechanism and which may be fixed to the object, for alignment of the object relative to the laser treatment device. A scanned laser beam is introduced on the input side, from the laser treatment device, along a beam path to the object with a reference structure. The reference structure lies on the beam path of the adapter and may be optically detected by means of the laser beam scanned over the region.
