A sealing array for positioning in an annular space between tubular members to provide a seal therebetween. Monofilar, polymeric fibers of multifilar helically-wound non-metallic fibers are preferred core wire materials. The clamping device may also be located within a hollow workpiece and controlled to move the jaws outward and engage the inner surface of the hollow workpiece in a self-aligned configuration. After alignment, the video based system is used to quickly measure and display in real-time a variety of performance characteristics of optical components such as lenses. The injectant is injected at a temperature of between about 100 F. The controller is adapted to communicate with the resource board to execute instructions to test the device under test.
