Scientists have solved an age old problem that will lead to the creation of more affordable quality lenses.
Optical technology has evolved greatly over the past 100 years. But this time there was one unsolved problem that has long haunted the industry of photography. Now, thanks to the sensational discovery of the Mexican physics, the producers of cameras has become much less of a problem. About the new invention in the field of optics reports segodnya.ua with reference to the journal Applied Optics.
Camera lenses and other optical systems made of spherical surfaces mainly because the lighter ones are formed. But this arises a problem that the light rays falling on the surface outside the center are refracted or reflected to a greater or lesser extent than rays entering in the dead center that leads to the problem called “spherical aberration” – the discrepancy between the focus of light rays passing at different distances from the optical axis.

Lens manufacturers have tried for years to eliminate this effect of using aspherical lenses. This is to some extent worked. But at the slightest structural change in production had to recreate corrective lenses, having a negative effect on the price and bulkiness of the design.
Rafael Gonzalez of the Mexican Technological Institute in Monterey, managed to create an incredibly complex formula that can be used to eliminate all spherical aberrations in the lens manufacturer. When testing 500 different light rays, the formula showed an average accuracy 99,99999999999%.

It is expected that the opening of the academic will reduce the production costs of lenses and may lead to the creation of less complex objective lenses, which are clearer and with fewer elements. It can also affect other areas of the image, as it will contribute to the creation of more precise microscopes, and advanced telescopes to observe deep space and a higher quality of cameras in smartphones.
