RAFAEL is a breakthrough snapshot spectroscopy method using reconfigurable lithium niobate photonics to achieve sub-ångström (0.5 Å) resolution with 73.2% transmittance and 2,048² spatial resolution at 88 Hz. It captured atomic absorption peaks from 5,600 stars in one shot—offering 100–10,000× better efficiency than leading astronomical spectrometers. RAFAEL sets a new standard for compact, ultra-sensitive spectroscopy from materials science to astrophysics.
