We present here the current state of a collection of promising ultraviolet technologies in preparation for the Habitable Worlds Observatory. Working with experts representing a significant number of groups working in the ultraviolet, we summarize some of the leading science drivers, present an argument for a 100 nm blue wavelength cutoff, and gather current state of the art of UV technologies. We present the state of the art of contamination control, a crucial piece of the UV instrument plan. We explore next steps with individual technologies, as well as present paths forward with systems level testing and development.

Pollux: high-resolution precision spectroscopy and polarimetry for the Habitable Worlds Observatory
astro-ph.IM 2026-08 conditional novelty 4.0 of 10

Pollux is a proposed five-channel spectropolarimeter that would give HWO high-resolution UV-to-NIR spectroscopy and polarization, if the remaining technology risks are retired.
