San’an Optoelectronics (China)

The fields where it stands highest, 2022–2025, ranked among every institution above the floor in each field.

Each strip is that field’s whole ranked pool, with the notch where San’an Optoelectronics (China) sits in it, in the colour of the band that rank falls in. The track under the rate is the rate itself: it carries no world mark, because the world rate differs by field (from about 6% to 21% in this record).

A dot further right is a better standing. Fields it was not ranked in over the whole record are left out.

Where its research is concentrated relative to its size: Atomic and Molecular Physics, and Optics takes 12.9× the share of its output that it takes of world research.

Location quotient, a volume reading rather than an impact one. It surfaces small, lopsided specialities.

Location quotient across every field it publishes in: outside the ring is more than an institution of this size would be expected to publish, inside it is less.

Against the world’s own shares — the tick on each track. Both are shares of its output, so they sit on one scale and can be read against each other as well as against the world.

Output in 2018–2022 was 228% higher than in 2013–2017.
