OPTICAL DESIGN, CALCULATION AND OPTIMIZATION OF OPTICAL SYSTEMS, ZEMAX. LENSES, FIBERS, LED, OPTICAL ELEMENTS DESIGN OF THE OPTICAL SYSTEMS EXPERIENCE: 1. Elaboration of an optical tube for the image output and transfer from the digital projector. 2. Elaboration of the optical resonator of the complex type for generating coherent optical radiation to produce a laser of metal vapor (copper, gold) with an extra high power. 3. Elaboration of the principle and optical scheme of an optical instrument – a diffraction spectral analyzer – to measure some physical and chemical properties of wheat grain . 4. Elaboration of a special lens for laser beam scanning, so-called "f-theta lens" (f-? lens) – for industrial lasers for processing (cutting) of materials. The specificity of the optical system of this objective lens is that the distance of the beam deflection from the center of coordinates in the focusing plane should be strictly proportional to the angle of beam deflection after the scanning element at the entrance to the f-?-lens. 5. Elaboration of the optical scheme of a diffraction monochromator. 6. Elaboration of an optical scheme of a spectral image analyzer based on backscattering, using fiber-optic conducting channels. 7. Elaboration of a specialized short-focus lens for the LED Bi-LED headlamp (lower and upper beam). Investigation of the methods for the formation of a wide beam with certain characteristics for roadway lighting in accordance with all necessary standards for the distribution of light flux and safety . 8. Elaboration (simulation) of the path of the rays in the optical system of a light microscope. Investigating of an optical and mechanical adapter for obtaining the necessary parameters of the image being formed by the lens in the focusing plane of microscope. 9. Investigation of the optical system of the eye. Methods for measuring, calculating and visualizing of the ray, wavefront and refractive aberrations of the eye. Participation in the investigation...etc.
