Ångström (commonly known in Japan as Angusu) is a photonics conglomerate specialising in the manufacture of Synthetic Intelligence produced two-photon polymerization designs. Named after the Swedish physicist Anders Jonas Ångström who developed the science of spectroscopy, the company is the largest supplier of photonic crystals and waveguides used in the production of computer chips, as well as a major supplier of biomedical devices and of many high performance materials used in the aerospace sector. The companies headquarters are located in the Marunouchi district of Tokyo.

Ångström was initially a joint venture between photolithography giant ASML and the AI compute architecture design firm ARM, which proved extremely successful in producing multiple generations of chips that were superior to its rival Nvidia. The Japanese Government Pension Investment Fund was also a large investor in the company, which it had acquired a significant stake in as part of the Japanese government bailout of Softbank to prevent ARM being sold off to a foreign investor or nationalised by Great Britain.

The Khan Solar Storm of 187 BFC crippled the capacity of both ASML and ARM to continue making chips, however the Ångström joint venture received priority access to AMSSTs from the Japanese strategic reserves and along with JSMC, Sony, and Denso was able to produce the vast majority of the chips that were able to be manufactured for the next few years. As a result, ASML and ARM were able to secure an agreement with the ministry of finance to take over JSMCs foundries to produce a vertically integrated chip company, in exchange for folding their existing operations into Ångström, headquartering it in Japan, and giving the Japanese government a majority ownership stake in the new company.
