UVoptical
UVoptical refers to the ultraviolet and visible portions of the electromagnetic spectrum, roughly from 10 nanometers to about 700 nanometers. This range is central to astronomy, spectroscopy, and materials science, enabling study of hot stars, nebulae, and many chemical processes. Observations in this domain are shaped by atmospheric transmission and instrument sensitivity across the band.
Ground-based work is feasible in the near-UV and visible bands but requires corrections for atmospheric extinction
Techniques include UV–visible spectroscopy and multi-band imaging. Detectors include CCDs optimized for optical light and UV-sensitive
Applications span astronomy—studying hot stars, galaxies, and the interstellar medium—and chemistry or biology, where UV–visible spectroscopy
Advances focus on detector efficiency, cross-calibration between UV and optical data, and space missions to access
