Description
Atomfair-TEA-739 Thermal Expansion Experimental Apparatus
Product Overview
The Atomfair-TEA-739 is a specialized experimental instrument categorized under interference, diffraction, and polarization technology. Adopting an electric heating method, it leverages the linear expansion of metal samples to drive a plane mirror, which induces changes in the optical path difference of the Michelson interferometer optical path and consequently alters the interference fringes. Through this precise mechanism, the device measures the length variation of the sample and ultimately calculates the linear expansion coefficient of metals.
Compared with traditional methods such as steam heating-optical lever, this apparatus boasts distinct advantages: compact size, short required sample length, low power consumption, and high measurement accuracy. It has been awarded the Third Prize in the National University Physics Experiment Teaching Instrument Evaluation, a testament to its reliability and performance in academic settings.
Key Experimental Application
Core Function: Precisely measure the linear expansion coefficient of metals.
Target Scenarios: Ideal for college and university physics experimental teaching. It helps users deepen their understanding of thermal expansion principles and interference measurement technology, serving as a valuable tool for both theoretical verification and practical skill development in academic laboratories.
