CLAIMS

1. A support for a vibrating component of an optical assembly that is adjacent to a frame, comprising:
an elastomeric rod having first and second ends, the first end being attachable to the component;
a frame; and
a rigid sleeve fastened to the frame and movable relative to the frame, the sleeve having a bore that opens to an inner end of the sleeve and is sized to receive the second end of the rod therein.
2. The support of claim 1 wherein the sleeve is threaded into an aperture in the frame and thus rotatable for movement relative to the frame.
3. The support of claim 2 including a set screw threaded into the aperture and against an outer end of the sleeve thereby to secure the sleeve against movement away from the rod.
4. The support of claim 2 wherein the bore extends partly through the sleeve, thereby defining within the sleeve a shoulder to limit the depth to which the second end of the rod is completely received within the bore.
5. The support of claim 4 wherein the length of the rod is selected so that there will be a gap between the inner end of the sleeve and the first end of the rod when the rod is completely received within the bore.
6. The support of claim 5 wherein the gap is less than the diameter of the rod.
7. The support of claim 4 further comprising an opening in an outer end of the sleeve opposite to the inner end of the sleeve, the opening joining the bore.
8. The support of claim 7 wherein the opening defines a socket for receiving a tool for threading the sleeve in the frame aperture.
9. The support of claim 1 further comprising locking means for securing the sleeve in place relative to the frame.

10. The support of claim 1 wherein the rod and bore are cylindrical and the diameter of the bore substantially conforms to the diameter of the rod to permit the rod to slide into the bore.
11. The support of claim 1 wherein the second end of the rod is received within the bore of the sleeve and retained therein without being attached to the sleeve.
12. An optical assembly supported in a frame comprising:
an optical element;
a frame;
supports extending between the optical element and the frame at spaced-apart locations, each support comprising:
an elastomeric rod having first and second ends, the first end being attached to the optical element;
a rigid sleeve fastened to the frame and movable relative to the frame, the sleeve having a bore that is sized to receive the second end of the rod; and
a transducer attached to the optical element and operable for vibrating the optical element.
13. The assembly of claim 12 wherein the transducer is supported by the frame using two supports that are configured as described in claim 12.
14. The assembly of claim 12 comprising four supports, the supports being arranged so that at least two of the four supports are opposite each other.
15. A method of supporting a vibrating component of an optical assembly adjacent to a frame, comprising the steps of:
attaching one end of an elastomeric rod to the component;
moving a sleeve that is carried on the frame until a length of the rod is received within a bore of the sleeve; and
locking the sleeve in position relative to the frame.
16. The method of claim 15 wherein the moving step includes locating a second end of the rod so that it abuts a shoulder in the sleeve.

17. The method of claim 16 including the step of selecting the length of the rod so that there is an exposed part of the rod between the sleeve and the component when the second end of the rod abuts the shoulder in the sleeve.
18. The method of claim 17 wherein the rod is cylindrical and the step of selecting the rod is such that the length of the exposed part of the rod is less than or equal to the diameter of the rod.
19. The method of claim 15 including the step of sizing the rod to slide into the bore and fit therein without the need for otherwise attaching the rod to the sleeve.
20. The method of claim 15 wherein the step of moving the sleeve comprises threading the sleeve within an aperture in the frame.
