- Instrument Description
This instrument employs an electric heating method. It utilizes the linear expansion of a metal specimen to drive a plane mirror; changes in the optical path difference within the Michelson interferometer cause shifts in the interference fringes, allowing the instrument to measure the change in the specimen’s length and, consequently, determine its coefficient of linear expansion. Compared to methods such as steam heating and optical levers, this instrument offers the advantages of a compact size, short specimen length, low power consumption, and high accuracy.
