Abstract: A stereoscopic endoscope includes an outer tube with an internal cavity, an insert, first and second image forming assemblies, first and second optical fiber bundles, and a first adapter. The insert is positioned within the outer tube and has a first side and a second side each including a concave outer surface. The insert holds the first and second image forming assemblies in a parallel relationship. Each optical fiber bundle substantially fills a non-circular void in the outer tube defined as a cross- sectional area between a respective side of the insert and a respective portion of an inner surface of the outer tube. The first adapter is configured to connect at least one of the first optical fiber bundle and the second optical fiber bundle to an illumination source.

Abstract: An objective element for use in an endoscope is provided. The objective element comprises a flat glass plate that is in contact with the plano side of a plano-convex lens. The side of the flat glass plate in contact with the plano-convex lens is coated with an opaque material other than an aperture that is in line with the axis of the plano-convex lens. Alternatively, the plano side of a plano-convex lens may be coated with an opaque material other than an aperture that is in line with the axis of the plano-convex lens.

Abstract: An opto-mechanical assembly including a housing and an internally supported optical element, such as a lens, mounted along an axis. At least one of the housing and optical element includes a radially extending chamber. Adhesive disposed in the chamber interacts with the housing and the optical element to prevent axial motion between the optical element and housing.

Abstract: A stereoscopic endoscope includes a proximal main body, an outer tube extended to a distal end of the endoscope and a pair of optical train subassemblies. Distal and proximal inserts in the distal and proximal ends of the outer tube, respectively, support the optical train subassemblies. First and second optical fiber bundles substantially fill all of the voids between the inner surface of the outer tube and the outer surfaces of the inserts and the optical train subassemblies.

Abstract: An opto-mechanical device, such as a lens cell, includes a housing having an axially extending chamber and an intermediate internal spacer that positions a sharp-edged lens in the chamber. The sharp-edged lens has first and second optical surfaces that intersect in a circumferential sharp edge. The housing positions an image sensor proximal to the sharp-edged lens for processing light therefrom.

Abstract: An adjustment system for use in a stereoscopic imaging system for adjusting the dipvergence and/or convergence of a displayed stereo image pair. A plano-plano window is mounted for tilting in one of the image paths thereby to enable the correction of dipvergence shifts, the adjustment of convergence or both.

Abstract: A lens structure and method for manufacture of such a lens. A lens element has multiple sawn planar faces between image forming surfaces so the lens element has a polygonal cross section. The manufacture includes the step of utilizing oversized conventional cylindrical lens elements and other optical elements formed into lens systems. The faces are sawn to reduce the overall size. The sawing can be applied to integral lens elements or assemblies or lens arrays.

Abstract: A rigid endoscope includes an outer housing subassembly that supports an optics subassembly. The outer housing subassembly includes concentric tubes with optical fiber for providing object illumination. The optics subassembly includes a tubular sheath sealed at both ends for carrying lenses and other optical elements. A slow-curing adhesive material fills an annular gap between the optics and outer housing subassemblies. The adhesive material has a tear strength that seals and positions the optics subassembly for normal use and that enables the optics subassembly to be withdrawn from the outer housing subassembly for repair.

Abstract: A convergence prism assembly with a housing and a prism structure having a plurality of prisms mounted in a unitary assembly.
