31. It features UD glass for suppression of chromatic aberration and a subwavelength coating for reduced ghosting. 32. Older convertible lenses may not be corrected for chromatic aberration , making them unsatisfactory with color film. 33. Am I correct in assuming it was some sort of chromatic aberration of the atmosphere or something? 34. In 1817 Carl Friedrich Gauss improved the doublets as the central lenses to correct for chromatic aberration . 35. This is a type of chromatic aberration , which often needs to be corrected for in imaging systems. 36. One advantage that mirror optics have over lens optics is that mirrors do not introduce chromatic aberration . 37. Chromatic aberration also affects black-and-white photography.38. The new flat lens does not suffer from the chromatic aberrations , or color fringing, that plague refractive lenses. 39. The refracting lenses used in the imaging spectrometer limit performance by the axial chromatic aberrations of the lens. 40. The engine still uses virtual textures ( dubbed particles which are correctly lit and shadowed, and chromatic aberration .
