LETI-30 Thermal Expansion Experiment Unit
Description
This device includes a Michelson interferometer and an oven, together
with a sensor and mirrors etc. Displacement of the specimen end is measured in
terms of the number of interference fringes counted. Therefore, the linear
expansion coefficient of the testing material can be calculated accurately.
