Mounting an optical component in an optical arrangement

摘要

There is disclosed a system and associated method for mounting an optical component in an optical arrangement. An optical component (1) is provided having a circular edge region (5). A mount (9) having a circular wall is also provided, the circular wall being configured for radially-spaced cooperation with the circular edge region of the optical component. The system is configured such that one of said circular edge region (5) and said circular wall (17) has a plurality of spaced-apart protrusions (23) provided around it. The other of the circular edge region (5) and the circular wall (17) has a plurality of spaced-apart recesses provided around it. The protrusions (23) and the recesses (7) are configured such that each protrusion (23) may be aligned with a respective recess (7) and engaged within said recess (7) via relative rotation between the optical component (1) and the mount (9). The system further includes an adhesive (32) for application between said circular edge region (5) and said circular wall (17) to adhesively fix the optical component (1) in position relative to the mount (9).

1. A system for mounting an optical component in an optical arrangement; the system comprising:
an optical component having a circular edge region; and a mount having a circular wall configured for radially-spaced cooperation with said circular edge region; the system being configured such that one of said circular edge region and said circular wall has a plurality of spaced-apart protrusions that protrude in a radial direction from said circular edge region or said circular wall; and the other of said circular edge region and said circular wall has a plurality of spaced-apart recesses that extend in a radial direction into said circular edge region or said circular wall, wherein said protrusions and said recesses are configured such that each protrusion may be aligned with a respective recess, and once each protrusion has been aligned with the respective recess, either the mount or the optical component or both can be then rotated about respective and coincident axes to cause relative rotation between the mount and the optical component, wherein said relative rotation is effective to move each protrusion into loose engagement within the respective recess, wherein the system is configured such that, when the optical component is mounted to the mount, there is a space between said circular edge region and said circular wall that extends along a circumferential path and separatus the circular edge region of the optical component from the circular wall of the mount in a radial direction, and wherein the system is configured such that when the optical component is mounted to the mount, each respective one of the protrusions extends in a radial direction into a corresponding, one of the recesses; the system further including an adhesive in the space that is between said circular edge region and said circular wall to adhesively fix the optical component in position relative to the mount.
