A split axis stage architecture is implemented as a multiple stage positioning system that is capable of vibrationally and thermally stable material transport at high speed and rates of acceleration. A split axis design decouples stage motion along two perpendicular axes lying in separate, parallel planes. A dimensionally stable substrate in the form of a granite, or other stone slab, or of ceramic material or cast iron, is used as the base for lower and upper stages. The substrate is precisely cut (“lapped”) such that its upper and lower stage surface portions are flat and parallel to each other.

A rigid support structure allows for faster and more accurate positioning of axially adjustable optical components in a laser processing system. Vibrational and thermal stability is improved when an optics assembly is housed in a rigid air bearing sleeve that is mounted to a support structure above a specimen stage.

A compression resistant isolator disposed between a direct fuel injector and a cylinder head of an internal combustion engine provides thermal, or thermal and vibrational isolation therebetween. A plurality of radially spaced rigid axial support members provide axial load support to maintain proper direct fuel injector positioning within the cylinder head bore. Spaces formed between the rigid axial support members may have isolation materials positioned therein. The implementation of the isolator may reduce the operating temperature of a fuel injector for direct injection, which is critical to avoid injector tip plugging.
