Its core business covers optical payloads and telescopes for Earth observation satellites, ground stations that track objects in orbit and receive laser communication links, and fully automated telescopes up to 1.6 metres for research institutes and defense test ranges. Two subsidiaries extend the offering: Dynamic Optics, acquired in 2020, builds deformable mirrors and lenses that correct atmospheric turbulence in real time, and ThinkQuantum, co-founded in 2021 with researchers from the University of Padua, develops quantum key distribution hardware under the QUKY brand and a quantum random number generator called THIKE.

Officina Stellare supplies optical payloads to Leonardo for programmes including PLATiNO and the HIREOS high-resolution optics project, and has built telescopes for Argotec's satellites on Italy's IRIDE Earth observation constellation and for Satellogic's imaging satellites. Its ground stations have gone to the German Aerospace Center, Cyprus University of Technology and Italy's ASI space agency, while ThinkQuantum won a EUR 4.8 million contract from Thales Alenia Space for ESA's SAGA quantum communication programme.

The company has been listed on Euronext Growth Milan since 2019. In October 2025 it signed an agreement for a business combination with Global Aerospace Technologies Group, backed by Investindustrial Growth III, to form a larger listed aerospace and defense technology group.
