Method for adjusting the holder of an optical element held in a holder, optical component and optical assembly

A method for adjusting a mount for an optical element, the optical element being held in the mount and comprising a first optical surface without rotational symmetry in relation to an imaging axis of the optical element, to a deviation of an actual pose of the first optical surface from a target pose of the first optical surface in the mount, the method comprising:

• specifying a target pose for the first optical surface in a given coordinate system in which a relative position and/or orientation of the mount is also specified;
• ascertaining an actual pose of the first optical surface in the given coordinate system;
• ascertaining a change in the relative position and/or orientation of the mount in the given coordinate system such that a deviation of the actual pose of the first optical surface from the target pose is compensated in at least one degree of freedom by changing the relative position and/or orientation of the mount in the given coordinate system;
• forming a reference element on the mount,
• wherein the reference element defines the relative position and/or orientation of the mount which realizes the ascertained change,
• wherein the reference element defines at least one specific azimuthal alignment of the mount in the given coordinate system, and
• wherein forming the at least one reference element on the mount is implemented by subtractive processing and/or by additive processing of the mount.

An optical component, comprising:

• a mount;
• and
• an optical element, the optical element being held in the mount and having at least one first optical surface without rotational symmetry in relation to an imaging axis of the optical element,
• wherein the mount comprises at least one reference element that defines in a given coordinate system a relative position and/or orientation of the mount with respect to a holding element when the mount with the optical element is mounted in the holding element, which relative position and/or orientation of the mount in the holding element compensates, at least in one degree of freedom, a deviation of an actual pose of the first optical surface from a target pose of the first optical surface in said given coordinate system, where at least the deviation of the actual azimuthal orientation of the optical surface from its target azimuthal orientation in said given coordinate system is compensated by the relative installation position of the mount in the holding element when the optical element is mounted in the holding element.
