摘要： PROBLEM TO BE SOLVED: To provide a method of evaluating the shape of an aspheric lens for accurately evaluating the aspheric shape in a short time without complicating an interferometer and without increasing cost.
SOLUTION: A system S for evaluating the shape of the aspheric lens irradiates a reference plane 5a with the optical component of a part of parallel measuring light, and irradiates an aspheric plane 7a to be inspected of the aspheric lens 7 with the remaining optical component via a null lens 6. An interference fringe is formed by making return measuring light that is reflected on the aspheric plane 7a to be inspected and returned via the null lens 6 interfere with return reference light that is reflected on the reference plane 5a and returned. The shape of the aspheric plane 7a to be inspected is evaluated based on the interference fringe. The null lens 6 is formed of a single lens, the first lens plane 6a has an aspheric shape substantially similar to a standard aspheric shape of the aspheric plane 7a to be inspected, and the second lens plane 6b is a flat plane perpendicular to the lens optical axis 6c of the null lens.
