Limited F-cone light source
First Claim
1. A limited f-cone light source, comprising:
- a source for emitting radiation;
micro-optics positioned adjacent the source for slowing the radiation emitted from the source for emitting radiation; and
a transducer for transversely shifting the micro-optics in and out of alignment, to selectively shutter the source.

Abstract
A shutter includes micro-optics having first and second concentrator arrays. A transducer laterally displaces one of the first and second concentrator arrays between transmissive and shuttered modes. In the transmissive mode, the arrays of concentrators are optically aligned to permit electromagnetic energy passing through the first array of concentrators to pass through the second array of concentrators. In the shuttered mode, the electromagnetic radiation is blocked from passing through the second array of concentrators. The concentrators may be compound parabolic concentrators, or lenslets positioned on opposing plates with pinholes printed therethrough. The shutter may increase f-number of radiation passing therethrough, and may be used in a limited f-cone radiation source with shuttering abilities, for example reducing f-cone of radiation output from the radiation source.
