Abstract: A processing arrangement comprising: a process chamber comprising an upper chamber wall, a lower chamber wall and two lateral chamber walls; an insulating structure, arranged between the processing region and each of the upper chamber wall, the lower chamber wall and the two lateral chamber walls, respectively, for thermally insulating the processing region, wherein the insulating structure is configured as gas-permeable at least in sections in such a way that a process gas from the processing region can flow out of the processing region in the direction in each of the upper chamber wall, the lower chamber wall and the two lateral chamber walls, respectively, through the insulating structure; and a gas channel, arranged between the insulating structure and each of the upper chamber wall, the lower chamber wall and the two lateral chamber walls, respectively, for pumping away the process gas which flows through the insulating structure.

Abstract: A method and a device for ascertaining and mapping data representing the optical imaging properties of an eye of a person, in which n different test images are displayed individually in succession on an electronically controllable monitor unit, are seen by the person from a settable viewing angle and at a settable distance, and are identified by means of an input comprising: a) ascertaining a characteristic viewing angle value at a given distance, at which a first probability for correct identification of the test images is achieved, b) ascertaining a characteristic distance value while maintaining the ascertained characteristic viewing angle value, at which a second probability for correct identification is achieved which is greater than the first probability, c) repeating steps a) and b).
