This development is characterized by an even distribution of light energy in focus, which makes it possible to compensate for equipment installation errors. This ensures stability and high accuracy even with minimal deviations in the optical system.
Miniaturization is a significant advantage of the development: the length of the “needle” does not exceed a few wavelengths of light, and the dimensions of the optical elements are only a few hundred nanometers. This sensitivity makes them an indispensable tool for nanotechnology.
Scientists continue to improve the technique of generating laser beams and develop new models to optimize the structure of microscopic optical elements.
