Abstract:
1. A micro-optic dual beam-splitter assembly comprising, in combination: a. a housing having an optical signal output port, a first tap signal output port, a second tap signal output port, and an optical path in the housing from an optical signal source to the optical signal output port; b. a first photoreceptor mounted in the housing; c. a second photoreceptor mounted in the housing; d. a first optical filter chip in the optical path between the optical signal source and the optical signal output port, comprising a first optical substrate having at least a first filter surface, a first optical tap surface, and a first thin-film optical filter on the first filter surface, e. a second optical filter chip in the optical path between the first optical filter chip and the optical signal output port, comprising a second optical substrate having at least a second filter surface, a second optical tap surface, and a second thin-film optical filter on the second filter surface, wherein
