Variable-Temperature Ellipsometer
Variable-Temperature Ellipsometer

Function Introduction:
This instrument is primarily used for analyzing the temperature-dependent optical properties and structural characteristics of various functional materials and bulk materials in fields such as nanofabrication, nanomaterials science, and nanobiology. It enables the analysis of optical constants for informational optoelectronic materials and devices. Measured objects include metals, semiconductors, superconductors, insulators, amorphous materials, magnetic materials, electro-optic materials, nonlinear materials, as well as isotropic and anisotropic materials.
