Abstract: An alignment apparatus for aligning components of an optical assembly include a chuck configured to support the optical assembly thereon, and an adjustable flexure assembly disposed around the chuck. The adjustable flexure assembly includes a plurality of flexures. The plurality of flexures are positioned relative to the chuck such that each of the plurality of flexures contact the optical assembly when the optical assembly is positioned on the chuck. Adjustment of a position of one or more flexures of the plurality of flexures adjusts an alignment of an optical axis of an optical component of the optical assembly when the optical assembly is positioned on the chuck, wherein the alignment apparatus is configured to align optical axes of the optical component to an angle of deviation of less than about 1,000 μrad and provide an extinction ratio within the optical assembly of greater than or equal to 1000:1.

Abstract: The method of aligning a cylindrical lens in a lens assembly includes attaching the cylindrical lens to a lens fixture and interfacing the lens fixture to a support structure in which the cylindrical lens can be placed in a frontwards and backwards orientation. The method also includes capturing respective first and second line images of respective first and second focus lines as formed by the cylindrical lens in the forwards and backwards orientations. The method further includes establishing a relative orientation of the first and second line images and using the established relative orientation to determine an amount of angular misalignment of the cylindrical lens relative to a reference direction provided by the support structure. The method can include rotating the cylindrical lens relative to the lens fixture to reduce the amount of angular misalignment to be within an angular alignment tolerance.
