Achromatic gradient index singlet lens |
| abstract |
A method of making an achromatic gradient index singlet lens comprising utilizing a gradient index material with a curved front surface in which light does not follow a straight line as it travels through the material and wherein different color rays traverse different curved paths, utilizing the natural dispersion of the curved front surface as a strong positive lens, and developing a weakly diverging GRIN distribution within the lens to balance the chromatic aberrations of the curved front surface. |
