ABSTRACT:
An apparatus is provided for measuring the shape of a surface of an object in compact size, in easy operability and with improved measurement precision. The apparatus is provided with a measurement relay system and an observation relay system for respectively guiding a reflected image of index on the object surface through an objective lens to re-image it at a certain magnification on a photoelectric converter, a member enclosing the measurement relay system and the observation relay system and disposed between the objective lens and the photoelectric converter, and rotating means for rotating the member such that either the optical axis of the measurement relay system or the optical axis of the observation relay system is made coincident with an optical path between the objective lens and the photoelectric converter.
