Express 6, 196-201 (2000). doi: 10.1364/OE.6.0001961094-4087http://hdl.handle.net/10919/46928The method used to manufature a Young's double pinhole interferometer is discussed. This interferometer is destined to be used in a surface profilometer using two wavelengths so that the zero order fringe can be determined. Hence stringent requirements are placed on the absolute length difference between the two output fibers of a single mode coupler. These requirements are discussed along with the manufacturing process. The interferometer is shown along with measurements showing a length difference on the order of 6 mu m.
