Abstract: A method for preparing an optical element for insertion into an optical system of an endoscope, wherein the optical element has an optical axis and a peripheral surface that is basically parallel to the optical axis, the method including: arranging the optical element in a mounting of a spindle which rotates the optical element about an axis of rotation of the spindle, aligning the optical element on the spindle such that the optical axis of the optical element coincides with the axis of rotation of the spindle, and subsequent to the aligning, removing an outer peripheral surface region of the optical element until the peripheral surface has a constant spacing from the optical axis of the optical element, wherein the removing of the outer peripheral surface region takes place by laser ablation.

Abstract: The invention relates to an optical microlens array and to a method for manufacturing an optical microlens arrays, wherein the method includes, among other things: providing a substrate having a first side and an opposite second side. The method further includes applying a photoresist to the first side of the substrate at least in portions, and structuring the photoresist such that the structured photoresist remains at predetermined locations on the first side of the substrate where one optical microlens each is to be later arranged. In addition, the method includes applying a hydrophobic coating to the first side of the substrate and subsequently removing the structured photoresist including the hydrophobic coating located thereon from the first side of the substrate. Furthermore, according to the invention, one microlens each is arranged on the spots of the first side of the substrate that are freed from the structured photoresist.

Abstract: An adaptive mirror that includes a substrate layer, on the first surface of which a reflecting layer and on the second surface of which at least one actuator is disposed. The substrate layer has a thickness of less than or equal to 1,000 ?m and the mirror having at least one further metallization for thermal compensation, as a result of which a thermal deformation of the mirror is avoided or preadjusted such that the desired curvature is set as a function of the reflected power.

Abstract: The invention relates to an adaptive mirror based on a ceramic substrate having a corresponding reflector and piezoelectric actuators, a cooling device being integrated in the substrate. The invention likewise relates to a method for the production of such mirrors. The mirrors according to the invention are used for the modulation or deformation of a laser wavefront of high power.

Abstract: A method for joining aligned discrete optical elements by which the optical elements can be joined in the aligned state. A thermal connection having long-term stability can be produced at little expense and with high positioning accuracy. Surface regions to be joined can be provided with at least one thin metallic layer by the method for joining aligned discrete optical elements. The surface regions are subsequently wetted using a liquid solder free of flux in a contactless dosed manner. The solder is applied to the surface regions to be joined via a nozzle using a pressurized gas stream.
