摘要:
The invention relates to processes for connecting an optical element of a microlithographic projection exposure apparatus to a mount, and also relates to an assembly. A process includes the following steps: forming a substance mixture at a processing temperature from at least a first component, which is solid at the processing temperature, and a second component, which is liquid at the processing temperature, the first component being dispersed in the second component, introducing the substance mixture in the unset state between the optical element and the mount, and setting the substance mixture so as to form a diffusion alloy from the first and second components.

摘要:
An optical measuring system is provided with a measuring machine that has at least one measuring element for determining locations and at least one measuring element for determining angles. At least one common reference surface is provided for the location-determining measuring element and the angle-determining measuring element.
摘要:
A holding arrangement for an optical element, in particular for a cylindrical lens, includes a basic structure surrounding an optical element and a mounting device by which the optical element is supported on the basic structure. The mounting device has two degrees of freedom so that the optical element can be supported by the mounting device in a manner that allows the optical element to rotate about both about an optical axis and an axis perpendicular to the optical axis. If the optical element is a cylindrical lens, the axis perpendicular to the optical axis can be an axis perpendicular to an axial direction of the cylindrical lens. The disclosure further relates to a manipulator unit for an optical system which includes a holding arrangement.
摘要:
An optical system, such as an illumination system, includes an optical arrangement having at least one optical element and at least one heat dissipation element configured to at least partially dissipate thermal energy generated in the optical element(s) to the outside environment of the optical system. The heat dissipation element(s) is(are) arranged without direct contact with the optical element(s).
摘要:
The invention relates to a device for holding a beam splitter element having an optically active beam splitter layer in an optical imaging device, the beam splitter element being connected to at least one support element that is fastened in the housing of the imaging device. The connection between the beam splitter element and said at least one support element is designed in such a way that the position of the beam splitter layer of the beam splitter element remains nearly constant relative to the housing independently of temperatures and of thermal stresses acting upon the beam splitter element.
