Reflecting Telescope Optics I: Basic Design Theory and Its ...
Paul (1935) invented its 3-mirror focal extension but, although the properties of
the afocal form were implicit in his own equations, he failed to recognize its
anastigmatic nature. With 3 colleagues, I have researched the question as to who
first ...

Observational Astrophysics
The aim of this optical configuration is to obtain, for a source located at infinity
and for a given aperture, an image that is as anastigmatic as possible, over as
wide a field as possible. The system is perfectly anastigmatic when all rays from a
...

A System of Applied Optics
Fifty years ago or more it was laid down by Joseph Petzval that the radius of
curvature of an anastigmatic image close to the optic axis, formed by two or more
collective or dispersive lenses, was given by the following formula— 1 l ._\' - g .

Anastigmatic Three-mirror Telescope
The shape of the large image area is helpful in space applications where several instruments may share the focal plane.

Astronomical Optics and Elasticity Theory: Active Optics Methods
If an optical system is free from Sphe 3, Coma 3, and Astm 3 aberration terms, the
three Seidel sums are ∑ SI = ∑ SII = ∑ SIII = 0, (1.72) and the design is said to
be an anastigmatic system in the third order. In this case, the tangential, mean ...

B. FLAT-FIELD ANASTIGMATIC SCHMIDT-CASSEGRAIN An anastigmatic
optical system is one with zero astigmatism, coma, and spherical aberration. The
condition for a flat field is zero Petzval curvature, hence p =1, and the surface of
best ...

These cameras are of the two-mirror or Cassegrain configuration, with two
mirrors, but a Schmidt correcting plate has been added to eliminate the spherical

these three aberrations are called aplanatic and anastigmatic to the third order.
To determine the Cartesian deviations for an aplanatic, anastigmatic system, we
set A, B, and C in Eqs. (9.32)—(9.34) simultaneously equal to zero and obtain ...
