Abstract
A support apparatus for an optical wave interferometer reference plate comprises a support member for supporting an outer peripheral face of the reference plate. The support member is bonded to the outer peripheral face of the reference plate at a plurality of positions spaced from each other along the circumferential direction of the outer peripheral face and adapted to deform elastically in a circumferential/diametric direction of the reference plate but less in the optical axis direction of the reference plate than in the circumferential/diametric direction.
