Old Problem Finally Solved

Great scientists like “Issak Newton” could find out temporary solutions for the phenomenonor the mystery of “Spherical aberration”(whichhas lastedfor centuries), but a Mexican student could solve it (while preparinghis breakfast).

Rafael Gonzalez, a student of the Institute of Technology in Monterrey, said to his university paper” I remember onemorning I was making myself a sandwich of bread with Nutella and suddenly I said’ Oh My God! I found it’.

I went to my room and started programming. I resolved the mystery and jumped out of joy and excitement”

The “Spherical aberration” is an optical effect in optical devices, lenses and mirrors  occurringbecause of more of refraction of light rays falling on a lens, or as a result of the reflection of light rays falling on the edge of a mirror compared to the rays falling nearing the center.

This optical phenomenon was discovered nearly 2,000 ago by the Greek mathematician “Diocles” .

Since then, scientists like Newton and Lebniz tried to solve the problem of maintaining clarity of images when the go through spherical lensesand they failed.

Newton could solve the problem chromatic aberration (the issue of focusing all the colors from the light source) but not the spherical aberration.

The problem was formalized in 1949 and became known in the scientific community as the (Wasserman-Wolf problem)which no one could solve until now… Industrial engineer, Gonzalez, who is currently working on his PhD in nanotechnology, collaborated with his friend and colleague Alejandro to solve what they called “mythical problem”.

Their work was published in Applied Optics journal. The previous (quick) solution was the use of tow aspheric lenses (rounded onlyon one side), but the calibration of such lenses depended on an inaccurate calculation.

However, thanks to Gonzalez and his solution, an accurate result can be derived regardless to the changes in the variables with a 99.99 percent success rate.

The resolution of spherical aberration could revolutionize the field of optics and improve the technology used in in telescopes and cameras all over the world.
