Mangin mirror

Mangin searchlight on the Eiffel Tower, 1889

A mangin mirror is a meniscus-shaped lens , the back of which is mirrored. Mangin mirrors are used in telescopes , for example, in order to achieve very specific corrections of the wave front by double passage of the light through the lens . The lens, which is also a secondary mirror , is named after the French officer Alphonse François Eugène Mangin (1825–1885) who developed it in 1876.
