41. Furthermore, chromatic aberrations can be corrected by using two or more refracting materials over the full visible range. 42. However, recent work attributes most of the stereoptic effect to transverse chromatic aberrations in combination with cortical factors. 43. Numerical modeling shows that chromatic aberration can yield useful chromatic information through the dependence of image acuity on accommodation. 44. Chromatic aberration is compensated by using a lens made out of materials carefully designed to cancel out chromatic aberrations.45. Chromatic aberration is compensated by using a lens made out of materials carefully designed to cancel out chromatic aberrations . 46. Their resolution is however limited by electron source geometry and brightness and chromatic aberrations in the objective lens system. 47. This reduces the amount of chromatic aberration over a certain range of wavelengths, though it does not produce perfect correction. 48. An apochromat is a lens or lens system with even better chromatic aberration correction, combined with improved spherical aberration correction. 49. Such illusions have been reported for over a century and have generally been attributed to some form of chromatic aberration . 50. Lenses in general exhibit axial chromatic aberration in which different colors of light do not focus in the same plane.
