摘要: By using two probe optical systems for measurement by disposing the probe optical systems with a test object sandwiched therebetween, an optical path length of light transmitted through the test object which is identified locally is calculated using an interference signal thereof. In addition, a geometrical thickness of the same part is calculated by measuring positions of the probe optical systems, whereby two calculated values are obtained. Based on the values and a calculated value for a reference object, a refractive index distribution of the test object is obtained.

摘要: On each of an optical axis of light entering a measurement object and an optical axis of light entering a reference mirror, compound lens whose achromatic condition, beam diameter condition, and color difference reduction condition are optimized using the focal length and/or the Abbe number of a collimator lens are placed. By correcting the wavefront by using the compound lens, the effect of the wavefront aberration is reduced, and the resolution in the shape measurement based on the optical interferometry is increased.

摘要: A light having a single wavelength which is emitted from a light emitting element comprising a light emitting diode, a semiconductor laser or the like is changed to a parallel light by a collimator lens. The parallel light emitted from the collimator lens which has been changed or is being changed to such a beam as to keep a small beam diameter for a long distance by a conical lens is irradiated on a surface of an object to be measured. The light diffused from the surface of the object to be measured is collected into a position detecting element by a condenser lens so that a distance on the surface of the object to be measured can be measured.
