Abstract: A step gauge and a reference gauge block are placed in a temperature-controlled chamber in parallel with each other. A temperature of the step gauge is changed to a first temperature and a second temperature using a measurement-target temperature adjuster and the temperature-controlled chamber. A distance between a first surface and a second surface of the step gauge is relatively measured at each of the first and second temperatures with reference to a distance between a first reference surface and a second reference surface of the reference gauge block. A coefficient of thermal expansion of the measurement target is calculated from the length of the measurement target at the first temperature and the length of the measurement target at the second temperature.

Abstract: In a spherical shape measurement method for measuring a surface shape, a sphere to be measured is made freely rotatable. The partial spherical shape of each measurement area, which is established so as to have an area overlapping with another measurement area adjacent to each other, is measured at each rotation position, and the surface shape is measured by joining the partial spherical shapes of the measurement areas by a stitching operation based on the shape of the overlapping area. In the state of detaching the sphere from the sphere hold mechanism to which the sphere is freely attachable and detachable, the sphere support table holds the sphere. The sphere is re-held at a different position, so that the shape of the entire sphere can be measured with high accuracy.

Abstract: A measurement target and a reference gauge are placed in parallel in an inside of a temperature-controlled chamber. After an interior temperature of the temperature-controlled chamber is set at a first temperature, a relative measurement of a length from a first surface to a second surface of the measurement target is performed with reference to a length from a first reference surface to a second reference surface of the reference gauge. Then, the interior temperature of the temperature-controlled chamber is set at a second temperature and a relative measurement of the length from the first surface to the second surface is similarly performed with reference to the length from the first reference surface to the second reference surface. A CTE of the measurement target is calculated based on the length of the measurement target at the first temperature and the length of the measurement target at the second temperature.
