Abstract: A high-pressure compressor and a system including a high-pressure compressor are described, wherein the high-pressure compressor includes at least one pressure container surrounding at least one media chamber and at least one compressor assembly. A diaphragm separates the at least one media chamber from at least one compressor chamber. The diaphragm extends along the at least one contour bar, which is connected to the at least one pressure container. The at least one contour bar is provided with at least one first connection and bores for supplying and/or discharging a gas or gas mixture. The diaphragm is fixed to the at least one contour bar by means of clamping pieces. The at least one pressure container has at least one second connection, which opens into the at least one media chamber and via which a medium can be introduced into and/or discharged from the at least one media chamber.

Abstract: A high-pressure compressor and a system with a high-pressure compressor are described. I one example, the high-pressure compressor has a housing that surrounds at least one compressor chamber and a media chamber, wherein the compressor chamber and the media chamber are separated from one another in the housing via a diaphragm. The housing has at least one first connection, which opens into the media chamber and via which a medium can be introduced into and/or discharged from the media chamber. The housing has at least one second connection, which opens into the compressor chamber and via which a gas or gas mixture can be introduced and/or discharged. The diaphragm comprises a polymer -based material and is deformable to compress a gas or gas mixture that can be introduced into the compressor chamber by introducing a medium into the media chamber.

Abstract: A high-pressure compressor and a system with a high-pressure compressor are described. In one example, the high-pressure compressor has a housing that surrounds at least one compressor chamber and a media chamber, wherein the compressor chamber and the media chamber are separated from one another in the housing via a diaphragm. The housing has at least one first connection, which opens into the media chamber and via which a medium can be introduced into and/or discharged from the media chamber. The housing has at least one second connection, which opens into the compressor chamber (330) and via which a gas or gas mixture can be introduced and/or discharged. The diaphragm is made of metal or a metal alloy and is deformable to compress a gas or gas mixture that can be introduced into the compressor chamber by introducing a medium into the media chamber.

Abstract: The invention relates to a device used for the photorefractive keratectomy of the eye, especially LASIK, uses an UV laser beam for ablating parts of the cornea. A centering light beam is arranged coaxially with respect to the fixing light beam and has a wavelength different from that of the fixing light beam. The device is provided with devices for measuring and evaluating the position of the scattered light/Fresnel reflection of the centering light beam on the front face of the cornea. The point in which the centering light beam passes through the front face of the cornea is used as the center of ablation.

Abstract: A device for the medical treatment of the eye with laser radiation uses auxiliary radiation for determining the eye position. With the aid of the auxiliary radiation, pictures are taken by means of a solid state image camera for determining eye movements and for causing the laser treatment radiation to follow accordingly. Infrared radiation sources, which are arranged in a triangle above the eye to be treated, are used for the auxiliary radiation.
