Abstract: The invention concerns a method for separating plate-shaped workpieces of mechanically brittle and nonmetal materials along any contour desired, comprising the following steps: Scratching of separating lines along the contour up to a depth T by means of a cutting device in at least one side of the plate-shaped workpiece is hereby characterized in that the plate-shaped workpiece is stimulated to bending vibrations at a vibration amplitude along the separating lines, so that the plate-shaped workpiece is completely separated along the separating line.

Abstract: Method for connecting an optical fiber to a GRIN lens, and a method for producing an optical filter module having an optical fiber and a GRIN lens, comprising arranging the optical fiber in contact with or in the immediate vicinity of the GRIN lens, directing a laser beam onto a part of the optical fiber and/or a part of the GRIN lens, the laser beam heating at least a part of the optical fiber and/or a part of the GRIN lens in such a way that a connection is formed between the optical fiber and the GRIN lens, and the optical axis of the laser beam being aligned oblique to the optical axis of the optical fiber, as well as optical filter modules produced in accordance with the method.

Abstract: A method for producing glass plates of any desired contour from sheet glass, comprising the following steps: scribing scribe lines into a least one face of the sheet glass along the contour down to a depth T, using a cutting device, and positioning the glass plate on a support. The inventive method is further characterized in that a defined force F is applied to the sheet glass so that it breaks along the scribe lines, said break extending through the entire thickness of the sheet glass. The flat glass may be sandwiched between two flexible plates prior to being placed on a base pad and being subjected to the breaking force.
