Here, we propose a cross\u2010scale synergistic optimization framework for a metasurface\u2010liquid lens hybrid imager, in which electrowetting actuation, system\u2010level aberration correction, and meta\u2010atom phase, group\u2010delay (GD), and fabrication constraints are optimized in a unified design space. The resulting system uses two liquid lenses, two spherical refractive lenses, and one achromatic metalens to realize 1.5 continuous visible\u2010band zoom over a 4\u20136\u00a0mm focal\u2010length range, a 10 field of view, and a 15.5\u00a0mm total optical length. Rather than acting as an isolated focusing element, the metalens serves as a compact dispersion and high\u2010order aberration modulator embedded in the full objective. Full\u2010system wave\u2010optics simulations show that boundary\u2013phase optimization improves multi\u2010wavelength focal consistency while exposing the residual halo imposed by phase folding. Etch\u2010height and system\u2010level tolerance analyses further indicate practical manufacturability margins for the hybrid design.<\/jats:p>","DOI":"10.1002\/nap2.70185","type":"journal-article","created":{"date-parts":[[2026,7,1]],"date-time":"2026-07-01T15:55:18Z","timestamp":1782921318000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Cross\u2010Scale
