Abstract
An adapter for mounting on an interferometer to provide a phase shift of the reference transmission sphere or flat used on the output of the interferometer is made of a monolithic body separated into two portions. The first portion is a fixed end support portion that mounts on the interferometer, and the second portion is a movable end support portion that mounts the sphere or flat that is used for transmission of the optic beam. The movable end support portion is mounted and the fixed end support portion are connected through flexure hinges that permit axial movement between the support portions, and a single actuator can be used between the support portions for causing axial movement. The flexure hinges are located so the adapter is very stiff against all motions except axial motions.
