Figure | Dual network chalcogenide glass reconciling flexibility with IR transparency for programmable adaptive optics. (a) S60Se40‑based DN chalcogenide glass, which integrates physically cross‑linked S8-ySey rings with polymeric [Se, S]ₙ chains. Representative transmission spectra and stress-strain curves illustrate how the DN architecture achieves both a broad IR transmission window and a compliant, hyperelastic mechanical response. (b) Visible-light and thermal IR images of IR-DLs under relaxed, compressive, and tensile states, showing deformation-dependent imaging evolution. Real-time focal switching and depth selectivity demonstrated with IR-DLs: the distant “NBU” object is sharply imaged in the relaxed state; focus shifts to the nearer “Duck” object under stretching; and original focus recovers upon strain release.
