Abstract
A system includes a dome-shaped optical component having a substantially circular edge and a mounting base for the optical component. A recess is in an outer surface of the optical component. A projection on an inner surface of the mounting base and is configured to engage the recess. An adhesive material is between the optical component and the mounting base. The adhesive material forms an upper band and a lower band with a void between the upper band and the lower band. The void is positioned relative to the recess in the outer surface of the optical component such that a bending stress in the optical component at the recess is less than what the bending stress would be without the void. A heater is inside and thermally coupled to the optical component.
Claims25
A system for mounting an optical component to a mounting base, the system comprising:
- a first retention mechanism configured to hold the optical component and the mounting base together;
- and
- a second retention mechanism configured to hold the optical component and the mounting base together, wherein the second retention mechanism comprises:
- a projection in a first one of the optical component or mounting base;
- and
- a recess in a second one of the optical component and the mounting base,
- wherein the projection is configured to engage the recess,
- wherein the first retention mechanism comprises an adhesive material in a joint extending around a perimeter between the optical component and the mounting base, and wherein the adhesive material forms an upper band and a base band with a void at least partially extending around the perimeter between the upper band and the base band, and wherein the perimeter comprises a substantially circular edge region of the optical component,
- wherein the upper band of adhesive material extends from a first end of the joint, through a portion of the joint where the projection engages the recess, and to a first end of the void, and
- wherein the base band of adhesive material extends from a second end of the void to a second end of the joint.
