<p>PROBLEM TO BE SOLVED: To provide a refractive index distribution-measuring reference element capable of further accurately measuring refractive index distribution of an optical element subject to a measurement without processing the optical element subject to the measurement, and to provide a device and method for measuring the refractive index distribution.SOLUTION: A refractive index distribution-measuring reference element for use in a measurement of the refractive index distribution in an optical element subject to a measurement includes a pair of first and second reference elements for clamping the optical element subject to the measurement. At least one of the first and second reference elements has one principal surface, the shape of which is inverse to a surface shape of the optical element subject to the measurement.</p> |
