Astrophysics demands higher precision in measurements across photometry, spectroscopy, and astrometry. Certain scientific cases necessitate not only precision but also a high level of accuracy. I will highlight the challenges involved, particularly in achieving spectral fidelity, which refers to our ability to accurately replicate the input spectrum of an astrophysical source. Beyond...
Astro2020 Decadal Survey study for Astrophysics articulated a number of exciting science ranging from exoplanet characterization to general astrophysics including galactic and stellar science that require high-efficiency, high throughput instrumentation ranging from ultraviolet through visible and near infrared. A major contributing factor to the throughput is determined by the efficiency and...
