Title: Leonid Y Ignatov: Innovator in Dichroic Polarizers
Introduction
Leonid Y Ignatov is a prominent inventor based in Moscow, Russia. He has made significant contributions to the field of optics, particularly in the development of dichroic polarizers. With a total of seven patents to his name, Ignatov's work showcases his innovative approach to material science and optical engineering.
Latest Patents
Among his latest patents is a dichroic polarizer and material that pertains to thermo-resistant and light-resistant dichroic polarizers based on thin films of dichroic materials, specifically organic dyestuffs. This invention features molecules that are ordered in a crystalline structure and applied to the surface of a substrate. The dichroic polarizer is characterized by containing at least one anisotropically absorbing film comprised of oriented molecules. This film is defined by the relationship of the main values of the semiaxes of the ellipsoid representing the imaginary and real parts of the anisotropic refraction coefficient. Another notable patent is a decorative material and method of its fabrication, which includes two polarizers and at least one phase-shifting plate placed between them. Each polarizer has a controlled direction of the polarization axis, enhancing the optical properties of the material.
