A closed flow-through microplate is described herein that can be used to perform high-throughput kinetic flow-through assays to detect biomolecular interactions like material bindings, adsorptions etc. . . that is helpful for example with testing new drugs. A method for manufacturing the closed flow-through microplate is also described herein.

Closed flow-through microplate and methods for using and manufacturing same

A method and apparatus for separating a first and second optical fibers including a fiber feed mechanism adapted to feed the first optical fiber and the second optical fiber, and a nozzle adapted to provide a displacing force on the second optical fiber, where the second optical fiber is displaced away from the first optical fiber to thereby separate the second optical fiber from the first optical fiber. In one embodiment, the displacing force is provided by a gas stream directed away from the nozzle while in another embodiment, the displacing force is directed towards the nozzle. In another embodiment, the apparatus includes a separation mechanism with a first guide, a second guide, a guide separator, and a deflector plate. In another embodiment, the apparatus includes a clamp mechanism with a first clamping pad having an offset extension that extends beyond an edge of a second clamp pad.

Method and apparatus for separating two optical fibers

The present invention relates to a method for terminating the end of an optical fiber. In particular the present invention relates to a method for forming a low reflectance termination on an end of an optical fiber. The method including the step of tensioning the optical fiber between two spaced apart points thereon. The method further including the step of moving a ball termination torch from a given location in a given direction with respect to the fiber such that a potion of the flame therefrom intercepts the fiber and severs the fiber into two pieces each having a tapered end. The method further includes the steps of retracting at least one of the tapered ends a predetermined distance in a direction away from the other of the tapered ends and continuing to move the torch such that the flame heats the at least one of the tapered ends to cause it to become shortened.

Method and apparatus for making fiber optic couplers

A method is disclosed for applying glue to a fiber optic coupler composed of a plurality of contiguously extending optical fibers, the fibers extending though the bore of a tube and through a longitudinally adjacent coupling region where the tube is collapsed around the fibers, the fibers being fused together in the coupling region, the diameters of the fibers in the coupling region being smaller than the diameters thereof in the bore. The method comprises: holding the coupler, and simultaneously injecting glue into both ends of the tube bore; wherein the coupler is oriented vertically, the glue being injected into the bore ends by positioning a hollow needle at each of the bore ends, the glue flowing through the needle in the bore at the top end of the tube at a rate greater than it flows through the needle in the bore at the bottom end of the tube.

A Mach-Zehnder interferometer for performing an optical function on a plurality of optical fibers is provided. The interferometer includes a first cane segment surrounding the optical fibers. The first cane segment forms a first optical coupling region. The interferometer also includes a second cane segment surrounding the optical fibers. The second cane segment forms a second optical coupling region. A phase shift region is formed by a discontinuity between the first and second cane segments for exposing the optical fibers. The optical fibers are suspended between the first and second cane segments within the phase shift region. A substrate is provided for supporting the optical fibers within the phase shift region.

Segmented cane mach-zehnder interferometer

A method for mechanically stripping the protective coating from a silica or glass optical fiber using a polymeric or soft metal blade having a hardness less than that of the glass optical fiber but greater than the protective coating. The blade is preferably selected from a group of polymeric materials, or alternately a soft metal, which is selected or treated so as to not detrimentally oxidize in conventional operating environments. For a silica-containing optical fiber, the blade has a hardness of less than approximately 125 on the Knoop hardness scale, and preferably less than approximately 60 on the Knoop hardness scale. A method of inhibiting damage to the exposed region of the silica-containing optical fiber comprises applying a substance that forms a protective layer to provide a barrier to particulates and moisture, and which does not inhibit subsequent processing of the optical fiber, selected from a group of silane-containing compounds.
