Abstract: An apparatus for laser machining by creating a plurality of discrete and separate beams which are sent to a deflecting device including a support and a plurality of individual elements that act independently and are individually controlled to machine different points on the workpiece simultaneously.

Abstract: A cooled field optical system which serves for imaging the exit pupil of an infrared telescope with primary mirror having a central hole (Cassegrain system) onto a cooled annular diaphragm (9) which defines the field of view of the detector (14) used. It contains a field mirror (6) which is arranged behind the field diaphragm (5) of the telescope and whose focal length and distance from the field diaphragm are so selected that the image of the exit pupil is produced in the direct vicinity of the rear side of the field diaphragm (5) with a central vignetting which is greater than or equal to the aperture (15) of the field diaphragm (5). For deflection out of the coaxial ray path there is used an annular mirror (8) which is inclined to the optical axis and is arranged directly behind the field diaphragm (5). It has an elliptical hole the projected size of which is approximately the same as the size of the free passage (15) in the field diaphragm (5).
