The dielectric stack enhances photon conversion near 2 eV, and a spatially resolved CMOS focal plane records the emitted photons with few-photon sensitivity. We calibrate the stack-lens-CMOS response in situ and use the calibrated focal-plane pattern in a template-based inference. With 904 h of search data and 404 h of background-control data, we observe no excess and set a 90% confidence-level upper limit of $\\kappa < 4.0\\times10^{-13}$ for dark-photon dark matter with mass 1.9$\\,\\mathrm{e","authors_text":"Alexandros Spiliotis, Husheng Guan, Paschos Ioannis, Pavlos G.
