Abstract: The invention relates to a process for producing components, in particular small glass plates such as windows for optical caps for optical components. The process includes providing a substrate, providing a carrier, joining a first surface of the substrate to a first surface of the carrier, machining the components out of the substrate, and detaching the components from the carrier in order to separate the components.

Abstract: The invention relates to a process for producing components, in particular small glass plates, for example as windows for optical caps for optical components. It is an object to provide an inexpensive process which ensures a high surface quality of the components. The process according to the invention comprises the steps of: providing a substrate (10), providing a carrier (12), joining a first surface (10a) of the substrate (10) to a first surface (12a) of the carrier (12), for example by laminating on a carrier film, machining the components (16) out of the substrate (10), for example by means of ultrasonic vibratory lapping or sand-blasting, with the components (16) being held together by the carrier (12) at least immediately after the machining-out step, and detaching the components (16) from the carrier (12) in order to separate the components (16).

Abstract: The micro titer plates, especially for micro reaction systems used in biotechnology, each have an array of special microstructures, which typically include micro cups and micro channels with different cross-sections. These microstructures are introduced into a preferably borosilicate glass wafer (18) by ultrasonic machining. Individual rectangular micro titer plates (19?) made from borosilicate glass for biotechnology are produced by cutting the structured glass wafer into individual micro titer plates. Particularly arrays of from 10 to 100 of these microstructures are formed in a 6-inch borosilicate glass wafer, in order to facilitate subsequent cutting of the wafer to economically manufacture a corresponding number of these micro titer plates (19?).

Abstract: During location-selective coating of areas of a substrate, other areas not to be coated are protected from coating by a mask. In order to provide a rapid location-selective coating of the substrate, a mask (3,3?) is arranged between a spray head (2) for spraying a coating material and the substrate (10) and travels with the spray head (2) during the coating process. Provisions are taken to avoid contamination of the mask (3,3?) during the coating process. The mask (3,3?) can include two elongated elements (3,3?), which define a coating slot, and a paper sheet (5) can be guided over the elongated elements (3,3?) to clean them during coating. Alternatively the mask can include two rotating disks, which define the coating slot, and excess coating material can be removed by rotating the disks.

Abstract: A method for quality control of a body comprising an optical raw material and for optimizing its being cut apart into optical elements is described, in which optical discontinuities in the body are detected and the optical elements are cut from those body parts that have as few discontinuities as possible or are essentially free of discontinuities. The method is distinguished in that the three-dimensional shape of the body is detected by means of three-dimensional geometry recognition in a coordinate system, and the optical properties of the body are detected, in body planes located above the other and formed of pixels, by means of scanning radiation, and from that, a three-dimensional image of the optical properties of the body is generated. The optical elements obtained by the method are suitable for DUV lithography, among other purposes.
