This is particularly critical in polaritonic heterostructures, where the near-field optical response is extremely sensitive to buried defects. Here, we present a high-resolution microreflectance mapping technique for assessing interfacial quality in vdW heterostructures and enabling the fabrication of twisted polaritonic stacks. By combining hyperspectral imaging with transfer-matrix-method (TMM) fitting, we determine flake thickness directly on PDMS stamps and quantify buried air gaps and other interfacial nonuniformities in assembled stacks. Using h-BN and \u03b1-MoO3 heterostructures as benchmark systems, we detect buried air gaps down to 7 nm with \u223c1 \u03bcm lateral resolution. Correlation with scattering-type scanning near-field optical microscopy (s-SNOM) confirms the quantitative accuracy of the method and shows that nanometric air gaps already produce measurable changes in phonon-polariton (PhP) propagation. Our results establish microreflectance mapping as an accessible far-field approach for quantitative interfacial control in polaritonic heterostructures, a key requirement for twistoptics applications. To facilitate implementation, we provide the analysis in an open-source graphical user interface that can be integrated into standard optical-microscope setups.<\/jats:p>","DOI":"10.1021\/acsanm.6c02110","type":"journal-article","created":{"date-parts":[[2026,8,18]],"date-time":"2026-08-18T16:13:14Z","timestamp":1787069594000},"page":"16286-16296","source":"Crossref","is-referenced-by-count":3,"title":["Unveiling
