Abstract: An interferometer for measuring thermal expansion coefficient can calculate the amount of length change of a measurement object more accurately without an error due to the deformation of the glass plate according to temperature. An interferometer for measuring thermal expansion coefficient includes a measurement target system(250), an optical system(210), and a vacuum chamber(200). The measurement target system comprises a measurement object(254) and a reference plate(255) on which the measurement object is loaded. The optical system splits incident light, modulates the frequency of the split light, and projects the modulated light to the measurement object and the reference plate respectively. The optical system also couples the respective light reflected from the measurement object and the reference plate, and detects the beat signal generated due to the interference generated in the optical coupling. The vacuum chamber maintains the vacuum condition with the measurement target system and optical system installed inside.
