Abstract
A high precision coordinate measuring device comprising a reflecting mirror fixed to a base, a movable holder displaceable in a direction perpendicular to the reflecting mirror, a position detector mounted on the movable holder and an interferometer for detecting a displacement of the position detector relative to the reflecting mirror. The interferometer has a measuring optical system and a reference optical system. This coordinate measuring device uses movable members light in weights thereof and permits performing measurements of lengths with high precision free from Abbe's error.
