Abstract:
1. A combined optical filter wheel, beam splitter, switch, and logic gate for a machine that can changeably pass, reflect, filter, or block light along multiple paths, comprising: a main housing, for providing a frame; a primary tube mounted to the exterior of said main housing, for providing a structured opening for light to pass and providing a structure to hold attachments, rigidly or threadably connected to said main housing, wherein said primary tube has a first central axis; a secondary tube mounted to the exterior of said main housing, for providing a structured opening for light to pass and providing a structure to hold attachments, rigidly or threadably attached to said main housing, wherein said secondary tube has a second central axis; a tertiary tube mounted to the exterior of said main housing, for providing a structured opening for light to pass and providing a structure to hold attachments, rigidly or threadably attached to said main housing, wherein said tertiary tube has a third central axis; said main housing arranged so that said primary tube and said tertiary tube are aligned so that said first and third central axes are coincident along a primary axis, and said secondary tube is aligned so that said second central axis is perpendicular to said primary axis; an optical routing subassembly, for providing a sub-housing for mounting a plurality of optics, rotatably attached to within said main housing wherein said optical routing subassembly is rotatable about a secondary axis, wherein said secondary axis is perpendicular to a plane defined by said primary axis and the second central axis of said secondary tube, wherein said optical routing subassembly is aligned so that light passing through said primary tube is incident upon at least one of the plurality of optics so that a portion of the light is selectively reflected through said secondary tube and the remaining portion of light is transmitted through said tertiary tube; at least one axle, for providing an attachment from optical routing subassembly to said main housing while allowing said optical routing subassembly to rotate about said secondary axis; a rotator connected to said at least one axle, for rotating said optical routing subassembly about said secondary axis.
