Microscopic SILs can be produced by focused ion beam (FIB) milling. This paper outlines the microscopic manufacturing process for SILs. We describe the pathway to manufacture a solid immersion lens: rst, a single emitter is optically located and characterized. Afterwards a SIL is manufactured around it. This is achieved by FIB milling.

Recent efforts to define microscopic solid-immersion-lenses (SIL) by focused ion beam milling into diamond substrates that are registered to a preselected single photon emitter are summarized. We show how we determine the position of a single emitter with at least 100 nm lateral and 500 nm axial accuracy, and how the milling procedure is optimized.

For harder materials, machinists will also prefer 2 flute micro-mills, even in materials such as steel where they're used to having 4 or more flutes in conventional milling. The reason is that micro-milling produces a larger volume of chips than conventional milling and fewer flutes provides larger gullet space. But there's a trade-off.
