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.
