摘要： Disclosed is a method for determining the focal position of a laser beam, according to which a plurality of linear patterns are first created on the surface of a sample substrate by the laser beam, the distance between the laser and the substrate surface being gradually modified. The width of the individual lines is then measured and the line having the smallest width is determined. The vertical setting associated with the smallest line width is evaluated and stored as the focal setting of the machine.

摘要： In a method for the laser drilling of holes in a circuit substrate with the aid of a perforated mask, a laser beam is moved in the region of the perforated mask on a circular path. The center point of the region lies concentrically with respect to the set position of the respective hole in the mask. Further, the diameter of the region is smaller than the diameter of the hole. At the same time, the diameter of the laser beam spot is chosen to be large enough that it always covers the center point of the perforated mask during the circular motion. As a result, an energy distribution of the laser energy, which is as uniform as possible, is achieved in the region of the perforated mask.

摘要： The invention relates to a modular optical recording system. According to the invention, a compact, flexibly configurable and expandable system structure for image recording, image stabilization and image correction is provided with an optical observation device that is to be arranged in the region of a preferably cylindrical housing concept. The recording system is designed in such a manner that a precise, play-free and frictionless mechanical correction of at least complete rotations about the optical axis and/or a precise and play-free adjustment of the flange focal distance is made possible.
