Abstract
A wedge-type interferometer is disclosed that is supported three-dimensionally by a cast inner shell, which contains a readily removable optical cartridge supporting the fixed and movable wedge-shape prisms of the interferometer. The fixed prism is supported from one side of a centerpiece of the cartridge while the movable prism is supported from the other side of the centerpiece for linear, scanning movement. The cartridge may be mechanically and optically aligned prior to insertion into the inner shell, and is easily removed if additional adjustments are required. A first corner cube mirror is supported by a plate secured to one wall of the inner shell and is aligned by micropositioner adjustment in the X-axis. A second corner cube mirror is supported by a plate secured to another wall of the inner shell and is aligned by micropositioner adjustment in the Y-axis. After alignment, the micrometers are removed, and the inner shell may be mounted in an outer, hermetically-sealed casting.
