Maksutovn.

Brit.

/makˈsuːtɒf/,

/ˈmaksᵿtɒf/, U.S.

/ˈmæksutɔv/

Origin: From a proper name. Etymon: proper name Maksutov.

Etymology: < the name of Dmitri D. Maksutov (1896–1964) who described the telescope in 1944 ( Jrnl. Optical Soc. Amer. 34 270).

Astronomy.

I. Compounds.

1. attributive. Designating or relating to a type of catadioptric telescope or camera which incorporates a deeply curved meniscus lens as a correcting plate; esp. in Maksutov telescope.

1958 Chambers's Techn. Dict. (ed. 3) 992/1 Maksutov telescope, see meniscus telescope.

1971 Monthly Notices Royal Astron. Soc. 153 262 There are two forms of Maksutov camera, with the meniscus concave or convex to the mirror.

1987 P. Moore Astron. Encycl. 242/2 Modern optical manufacturing processes enable the production of small meniscus corrector lenses at relatively low cost, with the result that Maksutov telescopes in the 4–10in (10–25cm) diameter range are relatively inexpensive.

1992 S. P. Maran Astron. & Astrophysics Encycl. 927/2 In the Maksutov design..the spherical surfaces are no longer concentric,..allowing corrections of axial chromatic aberration as well as third-order spherical aberration and coma.

II. Simple uses.

2. A Maksutov telescope or camera.
