A thousand times the light at the same resolving power – with no moving parts.
Static Fourier-transform interferometers for measurements that cannot afford to lose light: single photons against a daylight sky, weak Doppler-shifted returns, faint Raman signatures at standoff range.
Every spectrometer buys resolving power with photons. Our interferometer plays a different game.
Light or resolution
Resolution from path difference rather than from an aperture: the throughput advantage every interferometer is born with.
Static by construction
Two fixed gratings record the whole interferogram at once. Nothing scans, drifts, or wears.
Field-widened
Prisms in each arm widen the accepted solid angle by two to three orders of magnitude.
Heritage
Gratings in a Michelson since Connes (1958); field widening since 1963; spatial heterodyne spectroscopy since 1992; flown on WINDII and on MIGHTI aboard NASA's ICON. Every element has flown or been demonstrated.
