Abstract: Combined equipment for non-contacting determination of axial length (AL), anterior chamber depth (VKT) and corneal curvature (HHK) of the eye, are also important for the selection of the intraocular lens IOL to be implanted, particularly the selection of an intraocular lens (IOL) to be implanted, preferably with fixation of the eye by means of a fixating lamp and/or illumination through light sources grouped eccentrically about the observation axis.

Abstract: The invention relates to a method for determining haemostasis parameters by measuring vibration parameters of a resonator having a measuring surface which contacts a platelet containing sample fluid. The invention is characterized by the analysis of the characteristic of a vibration parameter over time, based on which the platelet function will then be assessed and a distinction will be made between the presence of an adhesion disorder or that of an aggregation disorder.

Abstract: The invention is directed to an optical system for a fundus camera for reflection-free opthalmoscopy having a beam path with refractive and reflective optical elements which are used substantially in common for illumination and observation or recording. An imaging mirror system substantially comprising a plurality of reflecting optical elements in the form of mirrors and is provided for illuminating and imaging the fundus. At least one optical element, for example, mirror, is formed as a freeform mirror with an imaging, reflecting freeform surface. The optical elements are arranged in a housing in a precisely defined position and attitude relative to one another in such a way that an imaging of the reflecting surfaces of the optical elements on the image of the imaged retina is prevented within a wide diopter range of the patient's eye to be examined.

Abstract: The invention is directed to an optical system for a fundus camera in which lens pairs are tilted relative to the imaging beam path to prevent flare. This tilting is carried out in two planes and these planes are preferably oriented perpendicular to one another.

Abstract: The invention relates to a device for observing the ocular fundus, in particular to a fundus camera. Said device comprises a light source (1b) for the provision of illumination radiation, an illumination optical path for directing the illumination radiation onto the ocular fundus and observation optics for reproducing the illuminated ocular fundus, the observation optics comprising a module (16b), whose refractive power can be electrically adjusted.

Abstract: In a device for positioning a tool in a working area wherein two spaced parallel horizontal guide tracks are provided and a guide slide is movably supported by each guide track, a coupler link is supported on each guide slide so as to be pivotable about a vertical pivot joint axis and the coupler links are joined to each other pivotably about another joint having an axis parallel to the vertical pivot joints of the coupler links, and a spindle extends from the other joint of the coupler links in alignment with the axis thereof so as to be linearly adjustable and is provided with a tool. The spindle with the tool is position-adjustable by linear movement of the guide slides along the tracks whereby the tool supported by the coupler links which are longer than the distance between the two guide tracks can cover also areas at opposite sides of the two parallel guide tracks.

Abstract: An adjusting apparatus and method for automatic setting of injectors are disclosed. The setting is carried out via accurate adjustment of the distance between an actuator and a lever element. In the process, an injector to be set is provided in the correct position in a measurement and setting station and is coupled to a pressure generating device. The setting element of the injector is then rotated in such a way that the injector switches through at a specific setting of the setting element. At the same time, the current values for the torque applied to the setting element, for the angular position of the setting element, for the exciter voltage applied to the actuator and for the pressure drop caused by the switching-through action are registered and compared with predefined parameters. If all the measured values agree with the predefined parameters, then the injector has been set correctly.
