Kind: research · Impact: medium

## In brief

- Researchers led by Adelaide University developed a speckle-based optical spectrometer.
- The device measures light wavelengths at a resolution of six femtometres.
- The team used it to measure the hyperfine structure of rubidium, which the source describes as a first direct measurement.

## Why it matters

The work shows that a speckle-based optical spectrometer can resolve very fine wavelength differences, such as rubidium's hyperfine structure, which matters for precision spectroscopy.
