anastigmat's Usage Examples:

The first three mirrors are curved (non-spherical), and form a three mirror anastigmat design for excellent image quality over the 10 arcminute field of view (one third of the width of the full Moon).

Paul Rudolph"s Protar was the first successful anastigmat (highly corrected [for the era] for all aberrations, including properly.

Such systems are called anastigmats.

satellite has a mass of 148 kilograms (326 lb), and carries a three-mirror anastigmat to track artificial objects in medium Earth orbit to geosynchronous Earth.

Systems in which the two astigmatic surfaces coincide are termed anastigmatic or stigmatic.

1915) was an optical lens designer, known for inventing the first double anastigmatic camera lens called Dagor in 1892.

for Paul Rudolph, German mathematical optician who designed the first anastigmatic camera lens, introduced by Zeiss in 1889, and the "Tessar" lens, introduced.

Secondary mirrors complete the f/20 anastigmatic imaging optics.

(See, for example, Ritchey-Chrétien telescope, or three-mirror anastigmats such as LSST.

The lens is a Neokor anastigmat f45mm/3.

Rudolph in the first anastigmats (photographic objectives).

A three-mirror anastigmat is an anastigmat telescope built with three curved mirrors, enabling it to minimize all three main optical aberrations – spherical.

(1865–1915), a German mathematical optician who designed the first double anastigmatic camera lens in 1893.
