ALIGNED TUBE RETAINERS

1 . A tube retainer, comprising;

a body configured to abut a face of a tube;

a plurality of flexure flanges extending radially outwardly from the body and configured to flex relative to the body to provide a retaining force to the body when installed in a housing assembly around the tube; and

a plurality of flexure legs axially extending from the body from a tube contact side of the body, wherein at least a portion of the plurality of legs include an inner diameter that is less than an outer diameter of the tube to provide a centering force to the tube.

2 . The tube retainer of claim 1 , wherein the body includes a flat disk shape.

3 . The tube retainer of claim 2 , wherein the body defines a center optical hole to allow light to pass to or from the tube.

4 . The tube retainer of claim 3 , wherein the body includes a plurality of circumferentially spaced holes through the disk shape.

5 . The tube retainer of claim 1 , wherein the plurality of flexure legs include an L shape.

6 . The tube retainer of claim 1 , wherein the plurality of flexure flanges are asymmetrically positioned on the body.

7 . The tube retainer of claim 1 , wherein the plurality of flexure flanges are less thick than the body.

8 . The tube retainer of claim 1 , wherein the plurality of flexure flanges and flexure legs includes at least three of each.

9 . The tube retainer of claim 1 , wherein the tube retainer is made of plastic or metal.

10 . An optical assembly, comprising:

an optical tube;

a housing assembly surrounding the optical tube, the housing assembly comprising a plurality of mounts, wherein the optical tube axially extends past the plurality of mounts; and

a tube retainer, comprising:

a body abutting a face of the optical tube;

a plurality of flexure flanges extending radially outwardly from the body each attached to a respective mount of the plurality of mounts such that each flexure flange is flexed relative to the body to provide a retaining force to the body to bias the tube axially into the housing assembly; and

a plurality of flexure legs axially extending from the body from a tube contact side of the body, wherein the plurality of flexure legs at least partially surround the optical tube, contact an outer diameter of the optical tube, and are flexed outwardly by the outer diameter of the optical tube to provide a centering force to the tube.

11 . The optical assembly of claim 10 , wherein the tube retainer is sandwiched between the housing assembly and an optical component mount.

12 . The optical assembly of claim 10 , wherein the tube retainer is screwed down to the mounts of the housing assembly to flex the flexure flanges.

13 . The optical assembly of claim 10 , wherein the body includes a flat disk shape.

14 . The optical assembly of claim 13 , wherein the body defines a center optical hole to allow light to pass to or from the tube.

15 . The optical assembly of claim 14 , wherein the body includes a plurality of circumferentially spaced holes through the disk shape.

16 . The optical assembly of claim 10 , wherein the plurality of flexure legs include an L shape.

17 . The optical assembly of claim 10 , wherein the plurality of flexure flanges are asymmetrically positioned on the body.

18 . The optical assembly of claim 10 , wherein the plurality of flexure flanges are less thick than the body.

19 . The optical assembly of claim 10 , wherein the plurality of flexure flanges and flexure legs includes at least three of each.

20 . The optical assembly of claim 10 , wherein the tube retainer is made of plastic or metal.
