गोलाकार विचलन के लिए स्वतंत्र या सही

aplanatic's Usage Examples:

apochromatic objectives can come in plan forms. aplanatic - a better corrected condenser than the commonest Abbe design.

aplanatic point will then be at about 35 cm.

aplanatic condenser.

This system will always be aplanatic. These objectives permitted a much larger aperture than a simple achromatic system.

By experiment Abbe proved that old, good microscope objectives, which by mere testing had become so corrected that they produced usable images, were not only free from spherical aberrations, but also fulfilled the sine-condition, and were therefore really aplanatic systems.

By homogeneous immersion the object-point can readily be reduced to an aplanatic point.

substances separated from one another by a spherical surface, then there are two points on the axis where they can be reproduced free from error by monochromatic light, and these are called " aplanatic points."

30.-0' is the virtual image on the notion of aplanatic points.

According to Abbe, a system can only be regarded as aplanatic if it is spherically corrected for not only one axial point, but when it also fulfils the sine-condition and thus magnifies equally in all zones a surface-element situated vertically on the axis at this point.

Abbe succeeded in computing microscope objectives free from error of the axis point and satisfying the sine condition for several colours, which therefore, according to his definition, were " aplanatic for several colours "; such systems he termed " apochromatic."
