  • Physicists have solved the main problem of photo lenses

    One of the main problems of optics for cameras is uneven sharpness throughout the frame — at the edges, it is lower than in the center. For more than 2000 years, a variety of scientists, including Isaac Newton, struggled to solve this optical problem. The new discovery of researchers may soon produce a revolution in the photo industry.

    The spherical surface of the lens causes the rays to deviate from the optical axis. This difference in light refraction results in uneven focus. In 1949, scientists G. D. Wasserman and E. wolf proposed a special form of aplanatic lens, calculated on the basis of the integral. Their work contributed to the appearance of aspheric lenses in modern cameras but did not completely solve the problem.

    In 2018, after three years of work in this direction, Hector Chaparro-Romo from the National Autonomous University of Mexico and Rafael Gonzales-to Start from the Monterrey Institute of technology managed to solve the problem which more than 20 centuries.


    "In the morning I smeared on bread "Nutella" and it dawned on me. Eureka! This is the solution! I rushed to the computer and began to enter the program code", — shares the experiences of one of the discoverers, Rafael Gonzalez.

    After a series of software simulations with 500 beams, the researchers found that the sharpness of the frame across the plane is 99.999999999%. So the formula for calculating a singlet lens of arbitrary shape without spherical aberration and astigmatism was obtained, and the corresponding article with a detailed description was published by the journal "Applied Optics".

    The discovery of scientists in the near future will finally solve the problem of spherical aberration. In addition, in theory, the production of singlet lenses is cheaper than traditional ones.
