Abstract: High efficiency collection of photons emitted by a point source over a widefield-of-view FoV is crucial for many applications. Multi-scale optics overimproved light collection by utilizing small optical components placed close tothe optical source, while maintaining a wide FoV provided by conventionalimaging optics. In this work, we demonstrate collection efficiency of 26% ofphotons emitted by a point-like source using a micromirror fabricated insilicon with no significant decrease in collection efficiency over a 10 mmobject space.
