IdealPhotonics' birefringence imaging microscope is a professional optical system that utilizes the phase retardation effect of optically anisotropic materials on polarized light to achieve high-contrast microscopic imaging. Its core function is to reveal microscopic information such as crystal structure, stress distribution, or the order of biomolecules by quantitatively measuring the birefringence properties of samples (e.g., retardation amount, fast axis direction).Based on the principle of polarization interference, it transforms the anisotropy of the sample (Δn·d/fast axis direction) into a high-contrast image, combining nanoscale phase sensitivity with quantitative analysis capabilities.
