To provide a stage for optical devices and an optical stage using it, capable of accurately carrying out observations, measurements or the like.

The stage 13 for the optical devices is equipped with a mount surface 13a, which is subjected to optical polishing and on which a substrate 14 is mounted, and a hole 21 formed in the mount surface 13a. The hole 21 has a chamfered section 21b, formed by chamfering on the side of the mount surface 13a, and the chamfer section 21b is subjected to the optical polishing, and a plane, intersecting with the mount surface 13a of the hole 21, is made to inclined downward from the mount surface 13a.
