A Fizeau type of infrared interferometer was fabricated using a infrared He-Ne laser (wavelength of 3.39 micron) as a coherent light source and an infrared imaging camera. Germanium crystals were used as a testing material to characterize the basic performance of this interferometer. The spacial variations of both thickness and refractive index were estimated for Ge samples with a wedged shape.
