Abstract: A contamination trap for use in a debris mitigation system of a radiation source, the contamination trap comprising a plurality of vanes configured to trap fuel debris emitted from a plasma formation region of the radiation source; wherein at least one vane or each vane of the plurality of vanes comprises a material comprising a thermal conductivity above 30 W m?1 K?1.

Abstract: An arrangement for micromanipulation of biological specimens includes a microscope, a motor-adjustable micromanipulator, and a common operating console having a motor-adjustable microscope functional element. The motor-adjustable micromanipulator has an injector. The common operating console includes a first operating element and a second operating element. Each of the first and second operating elements are selectably configurable to independently operate either of the motor-adjustable microscope functional element and the motor-adjustable micromanipulator.

Abstract: An operating knob (20) for an optical system (100) is disclosed. The operating knob (20) has a first and a second coaxially arranged rotating element (21, 22). The first and the second rotating element (21, 22) have at least partly conical form. The first rotating element (21) has at the side directly opposing the second rotating element (22) a larger diameter than the second rotating element (22) and a step is formed at the side of the second rotating element (22) directly opposing the first rotating element (21), wherein the step possesses a diameter which is approximately the diameter of the first rotating element.

Abstract: A device for controlling functions of a microscope is disclosed, the microscope system encompassing a stand base part (3). A central display (8) is integrated into the stand base part (3). The display (8) contains an operating menu (20) and an information mode (25), the operating menu (20) being constructed from a first region (211), a second region (221), and a third region (222). A main menu (21) is displayable in the first region (211), a submenu (22) in the second region (221), and information and action elements in the third region (222), the third region (222) being delimited on one side by the main menu (21) and on one side by the submenu (22), and the entire display (8) being usable for presentation in the information mode (25).

Abstract: An arrangement for micromanipulation of biological specimens (16), which comprises a microscope (1, 14) having at least one motor-adjustable microscope functional element and at least one motor-adjustable micromanipulator (7, 13) having an injector (20, 21), is described. According to the present invention, the arrangement has associated with it at least one operating console, (8, 23, 24), which comprises at least one operating element (9, 37, 38, 39) for operating both the at least one motor-adjustable microscope functional element and the at least one motor-adjustable micromanipulator (7, 13). The most important functions of the microscope (7, 13), the microscope stage (4), and the micromanipulator (7, 13) can thus be performed centrally at the operating console (8, 23, 24). The operating elements (9, 37, 38, 39) are mounted ergonomically on the operating console (8, 23, 24) in such a way that the hands of a user of the arrangement can remain on the operating console (8, 23, 24) while working.
