Abstract
A process is disclosed for correcting wave front deformations caused by an optical system (5). The wave front deformations are measured by means of a wave front measurement instrument. Based on the measurement results, at least two optical components are selected as optical correcting elements (1, 2) from a series of prefabricated optical components, for example cylindrical, with form errors of different types and magnitudes. They are then mutually aligned and brought into the path of the rays of the optical system (5). This process meets high tolerance requirements an may be easily and quickly applied in the course of manufacture of an optical system (5).

Process for correcting wavefront deformations which are caused by an optical system (5) and which are measured with the aid of a wavefront-measuring instrument, characterized in that introduced into the beam path of the optical system (5) are at least two optical correcting elements (1, 2) which are selected from a series of prefabricated optical components, where the prefabricated optical components are prefabricated to include form errors of different types and magnitudes, as a function of the results of the wavefront deformations measured with the wavefront-measuring instrument, and are aligned relative to one another and to the optical system.
A process for correcting wavefront deformations which are caused by an optical system and which are measured with the aid of a wavefront-measuring instrument comprising:
- introducing at least two optical correcting elements into a beam path of the optical system, wherein the at least two optical correcting elements are selected from a series of prefabricated optical components prefabricated with form errors of different types and magnitudes, and wherein the at least two optical correcting elements are selected based on the results of the wavefront-measuring instrument;
- and
- aligning the at least two optical correcting elements relative to one another and to the optical system to reduce the wavefront deformations caused by the optical system.
