"Il microscopio di Galileo" , Instituto e Museo di Storia della Scienza (in Italian) Christiaan Huygens, another Dutchman, developed a simple 2-lens ocular system in the late 17th century that was achromatically corrected, and therefore a huge step forward in microscope development. The Huygens ocular is still being produced to this day, but suffers from a small field size, and other minor disadvantages.

Blue is focused closer to the lens than red causing rainbow-like color fringing (chromatic aberration).Horder, pp 111–113Kingslake, pp 71–72, 316, 317Kraszna-Krausz, pp 3, 192, 858, 1029Peres, pp 175, 712, 717Ray pp 26–27, 341Stroebel and Zakia, pp 424–425 Most photographic camera lenses are achromatically corrected to bring blue and red to a common focus – leaving large residual green and violet chromatic aberrationsPeres, p 174Ray, pp 54–55 that degrades image sharpness; especially severe in long focus or telephoto lenses.Lefkowitz, p 90 If red, green and blue are brought to a common focus (plus other aberration corrections) with very little residual aberration, the lens is called apochromatic.

The Michelson Interferometer has played an important role in studies of the upper atmosphere, revealing temperatures and winds, employing both space-borne, and ground-based instruments, by measuring the Doppler widths and shifts in the spectra of airglow and aurora. For example, the Wind Imaging Interferometer, WINDII, on the Upper Atmosphere Research Satellite, UARS, (launched on September 12, 1991) measured the global wind and temperature patterns from 80 to 300 km by using the visible airglow emission from these altitudes as a target and employing optical Doppler interferometry to measure the small wavelength shifts of the narrow atomic and molecular airglow emission lines induced by the bulk velocity of the atmosphere carrying the emitting species. The instrument was an all-glass field-widened achromatically and thermally compensated phase-stepping Michelson interferometer, along with a bare CCD detector that imaged the airglow limb through the interferometer. A sequence of phase-stepped images was processed to derive the wind velocity for two orthogonal view directions, yielding the horizontal wind vector.
