Adjustable Optics Mounting Assembly for Vacuum Use

An assembly is shown in the figures which provides the capability of mounting an optical component (e.g., mirror, beam splitter, beam bender) through a vacuum chamber with the ability to fully adjust the component from the atmospheric side.

The assembly is adjustable for X tilt, Y tilt, and Z tilt, and can be rotated for 0 adjustment. As shown in the top view of Fig. 1, the degree of rotation is governed by the amount of clearance at the three hold-down screws 1A, 1B and 1C used to hold head top 7 in place in vacuum chamber wall 3.

As shown in the cross-section of Fig. 2, the assembly is sealed through vacuum chamber wall 3 by 0-ring 5 mounted in head top 7. The head top contains three adjusting screws, one of which is shown in Fig. 2 at 9A. These screws are arranged to have radius ends 120 degrees apart and are sealed by O-ring 11 in clamp 13. The adjusting screws contact head bottom 15 at 3 locations giving the X, Y, Z and 0 adjustment. The assembly is held together by spring 17, screw 19 and pin 21. Rotational adjustment is made by movement of dowel 23, shown in Fig. 1.
