Abstract: A flexure is disclosed for accommodating misalignments in an assembly. The flexure can include a first portion, a second portion, and a flexible portion coupling the first portion and the second portion to one another. The flexible portion can facilitate relative movement between the first and second portions in a plurality of degrees of freedom. The flexure can further include one or more stops operable to limit relative movement between the first and second portions in at least two of the plurality of degrees of freedom.

Abstract: An apparatus includes a Dewar having an endcap. The apparatus also includes a heat sink and a multiaxial thermal shoe having a thermal interface material and configured to thermally couple the endcap of the Dewar to the heat sink via one of at least two axial surfaces. The multiaxial thermal shoe is configured to transfer thermal energy between the endcap of the Dewar and the heat sink without structurally coupling the Dewar to the heat sink. The multiaxial thermal shoe may be configured to hold the thermal interface material against the endcap. The multiaxial thermal shoe may couple to the heat sink via a first axial surface in-line with an optical centerline or a second axial surface crosswise to the optical centerline.

Abstract: An apparatus includes a Dewar having an endcap. The apparatus also includes a heat sink and a thermal interface material configured to thermally couple the endcap of the Dewar to the heat sink. The thermal interface material includes an amorphous pliable material that is configured to transfer thermal energy between the endcap of the Dewar and the heat sink without structurally coupling the Dewar to the heat sink. A thermal shoe may be positioned between the thermal interface material and the heat sink, and the thermal shoe may be configured to hold the thermal interface material against the endcap. The thermal shoe may have (i) a smaller cross-sectional size in a portion of the thermal shoe contacting the thermal interface material and (ii) a larger cross-sectional size in a portion of the thermal shoe contacting the heat sink.
