▸ The reading
interpretive · artFrom 1960 to 1983 the metre itself was defined as a multiple of one orange wavelength of krypton-86 — for twenty-three years, all measured distance on Earth answered to this gas. It flashes in sports strobes and insulates double glazing. Mostly inert, occasionally definitive: the standard nobody sees.

▸ The lenses
▸ Discovery
William Ramsay + Morris Travers — found by spectral analysis of distilled air residues · England · 1898
▸ Stellar origin
s-process + supernova ejectaBuilt mostly by slow neutron capture, with isotope-specific contributions from r-process and supernova nucleosynthesis.
▸ Reactivity
Inert except in extreme conditions; KrF₂ forms only under cold UVHeavier noble gases break the inertness rule under enough provocation. KrF₂ exists at -78 °C and decomposes the moment you stop cooling it.
▸ Applications
- Krypton flash lamps (sports photography)
- Insulated double-glazed windows
- High-intensity airport runway lights
- Excimer KrF lasers (UV lithography)
▸ Curiosity
From 1960 to 1983 the meter was defined as a precise multiple of a wavelength of orange krypton-86 light.
