Assignee:

International Classification:

G21K 1/00

US Classification:

378145, 378 43, 378 70, 378205

Abstract:

A compound zone plate comprising a first zone plate frame including a first zone plate, a second zone plate frame including a second zone plate, and a base frame to which the first zone plate frame and the second zone plate frame are bonded. In examples, two more zone plates are added to make a four element optic. In the assembly process, the microbeads are used to ensure the parallelism, dial in the distance precisely between the zone plates by selecting the microbead size, possibly in response to the width of the frames, and ensure low friction lateral movement enabling nanometer precision alignment of the zone plates with respect to each other prior to being fixed by the adhesive. That is, when the frames are pressed together to ensure parallelism, it is still possible to align them to each other since the microbead layer facilitates the inplane movement of the alignment process.

Abstract:

Provided herein according to aspects of the present invention are resins that: (a) are suitable for use in additive manufacturing techniques such as bottom-up and top-down stereolithography, (b) produce objects that are bioresorbable, and (c) produce obects that are flexible or elastic (preferably at at least typical room temperatures of 25 C., and in some embodiments at typical human body temperatures of 37 C.). Such resins may include: (a) a bioresorbable polyester oligomer having reactive end groups; (b) non-reactive diluent; (c) optionally reactive diluent; and (d) a photoinitiator.
