| The aplanatic condenser is not corrected for color, hence objectionable color fringes are produced around the field of view diaphragm. |
| The results indicates that the aplanatic hologram lenses are feasible for optical disk applications. |
| These locations for which spherical correction has been optimized are called the aplanatic points. |
| Adding an aplanatic meniscus lens to an achromatic lens can increase relative aperture without introducing additional spherical aberration. |
| These aplanatic components have the property of converging the light without adding spherical aberration to the image and provide an increase in the N. A. without introducing significant aberration. |
| We can apply the same reasoning to rods and transformation of cylindrical diverging wavefront using aplanatic points of the rods. |
