Abstract
An interferometer mounting mechanism that consists of a horizontal shaft rigidly connected to the interferometer in axial alignment with the optical path of the instrument and protruding through an opening in the center of the transmission flat. A sample stage adapted to receive a computer-drive disk is attached to the distal end of the shaft, so that the stage is directly and rigidly connected to the interferometer. The sample stage consists of a hub capable of retaining a disk in precise alignment with the transmission flat by hanging its center hole on two support posts and resting the disk on three pressure tips on the hub. A system of push-pull adjustment screws is provided to set the proper tip/tilt of the disk.
