Unfortunately, the same characteristics that make these patterns sensitive to measurements also leave them vulnerable to undesired external influences, such as air turbulence, aberrated optics ...

The incisions biomechanically induce a hyperprolate, negatively aspheric corneal shape, and aberrated refractive profile with both negative spherical aberration and positive secondary spherical ...

Aspherical optics are, however, difficult and expensive to manufacture, and simpler designs are desirable. The Schwarzschild objective replaces the aspheres with spherical elements, as shown in Fig. 1 ...

But then we'll adjust the mirrors to bring all the spots together to make a single star that's not aberrated and good for normal operations. We know Webb works." Gillian Wright: "The technologies ...

"But we'll adjust the mirrors to bring all the spots together to make a single star that's not aberrated and good for normal operations. "It's a long process. It can take up to three months during ...
